Plaintiffs appeal from the district court’s order granting partial summary judgment in favor of the defendant Merrill Lynch, Pierce, Fenner & Smith (hereinafter Merrill Lynch), and further granting Merrill Lynch’s motion for stay of the remaining claims pending arbitration.1
*219In their complaint, plaintiffs John J. Cur-ran and Jacquelyn L. Curran sought damages from Merrill Lynch for false representations made by its agents which induced plaintiffs to open discretionary commodity trading accounts with Merrill Lynch and for the broker’s subsequent mismanagement of those accounts.
Specifically, plaintiffs allege that the accounts constitute investment contracts under federal law, and that Merrill Lynch violated Section 5 and Section 12(2) of the Securities Act by failing to file a registration statement before making an offer and sale of a security. Plaintiffs also assert that defendant made untrue statements of material fact, omitted to state material facts necessary to make the statements not misleading, and employed a device, scheme, or artifice which operated as a fraud upon plaintiffs, all in violation of Rule 10b- 5, § 17(a) of the Securities Act, § 6(a) of the Commodities Exchange Act, § 410(a)(2) of the Michigan Uniform Securities Act, and principles of common law. Plaintiffs further allege that defendant breached the commodity account agreement by: (1) failure to manage the accounts in a skillful and prudent manner; (2) failure to observe certain safeguards and stop-loss limits; and (3) failure to employ a scientific and comprehensive investment plan and instead, engaging in reckless and haphazard trading with the sole intention of generating large commissions.
The district court ruling presents several issues of first impression in this circuit. Initially, we must determine whether a discretionary trading account in commodity futures constitutes a “security” subject to the registration requirements and enforcement provisions of the federal securities laws. The court below determined the account was not a security and entered partial summary judgment against plaintiffs’ securities claims, relying primarily on Milnarik v. M-S Commodities, Inc., 457 F.2d 274 (7th Cir.), cert. denied, 409 U.S. 887, 93 S.Ct. 113, 34 L.Ed.2d 144 (1972). In Milinarik the Seventh Circuit, speaking through Mr. Justice Stevens (then Judge Stevens), held that a discretionary trading account in commodity futures is not a security because such accounts lack the “common enterprise” element required for an investment contract under Securities Exchange Commission v. Howey, 328 U.S. 293, 66 S.Ct. 1100, 90 L.Ed. 1244 (1946). We agree.
Further, we reject plaintiffs’ contention that the account involved here, though not a security, should be treated as such because it was fraudulently misrepresented to include the essential elements of a common enterprise.
This appeal also presents substantial questions whether the district court should have stayed plaintiffs’ other claims pending arbitration, and whether in all events the lawsuit is barred by a one-year limitation period provided for in the contract in question. Finally, for reasons set forth later, we have been obliged to consider, sua sponte, and have determined that an implied private right of action exists under the Commodity Exchange Act.2
I. FACTS
Plaintiffs, as customers of the broker-dealer defendant, Merrill Lynch, lost a substantial sum of money in the highly volatile and speculative futures market. These losses were allegedly sustained due to Merrill Lynch’s mismanagement of plaintiffs’ discretionary commodity accounts in a manner contrary to representations made when the contracts were made.
In 1973, plaintiffs opened several accounts for trading commodity futures in defendant’s “Guided Commodities Account Program.” In the written Customer *220Account Agreement, the parties agreed to submit any dispute under the contract to arbitration within one year after the accrual of such claim. As Merrill Lynch interprets the program, a customer deposits an amount he is prepared to risk in his own commodity trading account. Merrill Lynch further claims that although specific recommendations for purchase and sale are made by commodities specialists, the ultimate decision to act or not is made only upon the customer’s direct order. However, plaintiffs have raised a question of fact with respect to that issue in the pleadings and Merrill Lynch has acknowledged that, for purposes of this appeal only, the plaintiffs’ commodity trading accounts must be deemed discretionary, with trading control in the hands of Merrill Lynch.
Plaintiffs allege that Merrill Lynch fraudulently misrepresented how the account would be handled with respect to other accounts in the same program. They insist that the discretionary account was represented to involve several unique elements in that: (1) the program involved a specified number of investors who could not withdraw their capital for a minimum of 18 months; (2) the accounts were to be controlled by an individual trader who could direct buy/sell decisions on a broad basis and thereby control fluctuations in the market; (3) the capital availability and buying power generated by control over the group of accounts would create a multibuyer effect allowing the trader to buy as though he were buying five times greater the amount than if dealing with a separate account.
To support these contentions, plaintiffs state that after they opened the first account of $100,000 Merrill Lynch made all trading decisions and exercised complete control over plaintiffs’ accounts. Initially, plaintiffs realized profits on the trading activity and at one point withdrew $101,-007.80. Later, the accounts declined in value and plaintiffs suffered excessive trading losses which they blame upon improper and excessive trading activities and a failure to observe the “stop loss” procedures represented to exist as part of the program. On several occasions, plaintiff John J. Curran requested that the accounts be closed and that plaintiffs be “cashed-out.” On each occasion, except the final one (at which time plaintiffs’ capital had been reduced to approximately $6,000), defendant either refused to follow his advice or convinced Cur-ran that he was required to stay in the program for 18 months. In April, 1974, the defendants assented to plaintiffs’ demands to “cash-out” the accounts. At that time plaintiffs assert that the accounts had declined in value approximately $175,000. Significantly, Merrill Lynch had in the meanwhile been paid $44,500 in commissions.
II.
A commodity future is a standardized contract for the purchase and sale of a fixed quantity of a commodity to be delivered in a specified future month at a price agreed upon when the contract is entered into. See generally Bromberg, Securities Laws § 4.6, at 82.181 (1975). Futures contracts are traded by futures commission merchants and floor brokers on national exchanges, or “contract markets,” which are regulated by the Commodity Futures Trading Commission (CFTC).
Generally, a futures contract seller is characterized as being in a “short” position since he must deliver the commodity in accordance with the contract in order to receive the purchase price. The purchaser of a futures contract is labeled as holding a “long” position in that he must pay the contract price before receiving the commodity. Ordinarily, the number of trades far exceeds the number of actual deliveries since futures contracts are the subject of speculation by traders seeking to profit from their trading acumen, rather than from actually delivering or receiving the commodity involved. As Judge Kinneary stated in Berman v. Bache, Halsey, Stuart, Shields, Inc., 467 F.Supp. 311, 315-16 (S.D. Ohio 1979), “a commodities future contract is little more than a wager that the market price of a given commodity will change in a *221given direction by a specified future date.” Normally, the trader’s expectation of profit arises solely from speculative hope based upon his expertise in the market.
Although bare commodities are generally not considered securities, some courts have determined that an investment contract is formed when commodity accounts are managed by the seller or affiliate.3 Typically, a customer trading in a discretionary commodity account gives the broker authority to buy and sell at the broker’s discretion, without prior consultation with the customer. Discretionary accounts are more common for commodities where fast trading is required due to sharp movement in prices, a factor further magnified by the high leverage that results from generally low margin requirements.
While the underlying commodities themselves do not constitute securities, whether a discretionary commodity account constitutes an investment contract, and thus a security under the federal securities laws, is a current topic of dispute in the federal courts. The question is particularly difficult where there is no actual pooling of the customer’s funds with those of other investors.
Whether a particular financial arrangement is considered an “investment contract,” 4 and therefore subject to the filing requirements of Section 5, Securities Act of 1933, and the antifraud provisions of Section 10 and Rule 10b.....5 of the Securities Exchange Act of 1934, is usually determined by measuring the arrangement against the requirements set forth in Securities & Exchange Commission v. Howey, supra. In Howey, the Supreme Court defined an investment contract as “. a contract, transaction or scheme whereby a person invests his money in a common enterprise and is led to expect profits solely from the efforts of the promoter or third party . . . .” Id., 328 U.S. at 298-99, 66 S.Ct. at 1103. It is universally recognized that the Howey test is comprised of three basic elements: (1) an investment of money, (2) in a common enterprise, with (3) profits to come solely from the efforts of others. Further, although the Supreme Court offered little guidance in defining these elements, it did note that the definition of a security,
[Ejmbodies a flexible rather than static principle, one that is capable of adaptation to meet the countless and variable schemes devised by those who seek the use of money by others on the promise of profits.
Id. at 299, 66 S.Ct. at 1103. See also United Housing Foundation, Inc. v. Forman, 412 U.S. 837, 852, 95 S.Ct. 2051, 2060, 44 L.Ed.2d 621 (1975).
The current debate usually focuses on whether a horizontal or a vertical relationship satisfies the “common enterprise” language of Howey. Plaintiffs assert that the common enterprise requirement is met by a vertical relationship, which essentially is a one-on-one arrangement between the customer and broker. Horizontal relationships are those between an individual investor and the pool of other investors. In rendering summary judgment against plaintiffs’ *222securities claims the district court applied the horizontal approach adopted in Milnarik v. M-S Commodities, Inc., supra5
In Milnarik, Justice Stevens began his inquiry by observing that, in searching for the meaning and scope of the word “security,” courts should disregard form in favor of substance and place the emphasis on economic reality. Tcherepnin v. Knight, 389 U.S. 332, 88 S.Ct. 548, 19 L.Ed.2d 564 (1967). He observed that not “every conceivable arrangement that would fit a dictionary definition of an investment contract was intended to be included within the statutory definition of a security.” Id. at 275-76. Justice Stevens interpreted Securities & Exchange Commission v. Howey, supra, as stressing the significance of the common enterprise element in determining whether particular investment contracts are securities. The original complaint in Milnarik alleged a discretionary arrangement remarkably similar to the relationship here. The court noted, however, that “the success or failure of those other [customer’s] contracts had no direct impact on the profitability of plaintiffs’ contract. [The broker’s] various customers were represented by a common agent, but they were not joint participants in the same investment enterprise.” Id. at 276. The significance of this finding is found in Milnarik’s adoption of the district court’s further determination that:
In essence, this contract creates an agency-for-hire rather than constituting the sale of a unit of a larger enterprise. No matter how many different persons Nelson became an agent for under similar or even identical discretionary contracts, his relationship with each would remain as that of agent and principal. Each contract creating this relationship is unitary in nature and each will be a success or failure without regard to the others. Some may show a profit, some a loss, but they are independent of each other. No matter how many discretionary trading accounts Nelson may have had with other principals, the “security” “issued” to the plaintiffs, their discretionary trading account, could not be offered to anyone else. Although this Court recognizes that the registration requirements of Section 5 are for the protection of the public and that any exemption therefrom must be strictly construed against one claiming it, Securities and Exchange Commission v. Ralston Purina Co., [346 U.S. 119, 73 S.Ct. 981, 97 L.Ed. 1494]; Securities and Exchange Commission v. Culpepper, 270 F.2d 241 (2d Cir. 1959), the unitary nature of the contract here involved is not overcome even when the transaction is viewed most strongly against the defendants.
Id. at 277.
We reject plaintiffs’ assertion that a pooling of investors’ interests is not essential to a finding of common enterprise and hold that Justice Stevens’ reasoning in Milnarik best comports with the language of Howey since the agreement entered into here was solely between plaintiffs as investors, and Merrill Lynch as broker, and it did not include a “common enterprise” element. Therefore, we' conclude the district court had no jurisdiction under the federal securities laws and properly dismissed those claims for failure to state a cause of action.
By adopting Milnarik, we necessarily reject the vertical commonality approach primarily championed by the Fifth Circuit’s decision in Securities & Exchange Commission v. Continental Commodities Corp., 497 F.2d 516 (5th Cir. 1974).
In Continental Commodities, the district court followed the Seventh Circuit’s reasoning in Milnarik, supra, primarily because each individual invested in different accounts and the investors had no expectation that they would share in a common *223fund comprised of the return on their investments.6 The Fifth Circuit, however, refused to adopt the Milnarik approach and emphasized its view that a pro rata sharing of profits is not critical to a finding of commonality. Rather, the court preferred a resilient standard which would comport with the remedial purposes of the Securities Act of 1933 and the Securities Exchange Act of 1934. The court applied a test which the Ninth Circuit formulated to deal with the various pyramid-type investment schemes challenged in the courts as securities: a “common enterprise is one in which the fortunes of the investor are interwoven with and dependent upon the efforts and success of those seeking the investment or of third parties.” Securities & Exchange Commission v. Koscot Interplanetary, Inc., 497 F.2d 473 (5th Cir. 1974), quoting Securities & Exchange Commission v. Glen W. Turner Enterprises, 474 F.2d 476, 482 n. 7 (9th Cir.), cert. denied, 414 U.S. 821, 94 S.Ct. 117, 38 L.Ed.2d 53 (1973).7 Further, the court expressed the notion that “the critical factor is not the similitude or coincidence of investor input, but rather the uniformity of impact of the promoter’s efforts.” 497 F.2d at 478.
In Continental Commodities the Fifth Circuit vigorously criticized Milnarik’s elevation of the pooling ingredient to exalted status and held that “the critical inquiry is confined to whether the fortuity of the investments collectively is essentially dependent upon promoter expertise. . That it may bear more productive fruits in the case of some options than it does in others should not vitiate the essential fact that the success of the trading enterprise as a whole and customer investments individually is contingent upon the sagacious investment counselling of Continental Commodities.” Id. at 522.8 Although this approach has attracted some support,9 we believe *224that no horizontal common enterprise can exist unless there also exists between discretionary account customers themselves some relationship which ties the fortunes of each investor to the success of the overall venture. Thus in our view the finding of a vertical common enterprise based solely on the relationship between promoter and investor is inconsistent with Howey.
Further support for Milnarik’s rationale is found in Berman v. Bache, Halsey, Stuart, Shields, Inc., 467 F.Supp. 311, 315-16 (S.D.Ohio 1979), where Judge Kinneary observed that:
a finding of a common enterprise based solely upon the fact of entrustment by a single principal of money to an agent effectively excises the common enterprise requirement of Howey. The test would simply require (1) the investment of capital (2) with the expectation of profit through the efforts of others, for nothing more is involved in a single discretionary trading account. Although the precise meaning of the phrase “common enterprise” is far from clear, nowhere in Howey or later Supreme Court decisions is it intimated that that phrase is somehow redundant of other elements of the definition of a security.
Id. at 319.
III.
Even though we conclude that a discretionary commodity account is not a security, plaintiffs still claim the district court erred in dismissing the securities claims because while a “common enterprise” was not shown to exist, it was nonetheless fraudulently promised. In short, plaintiffs make the interesting argument that the unfulfilled and fraudulent promise of a “common enterprise” with other Merrill Lynch customers itself brings the actual agreement made within the definition of a “security” and hence confers jurisdiction under the federal securities laws. Under such a circumstance, they urge it was improper for the district court to have entered summary judgment under Rule 56 because the deposition and affidavits submitted by the parties in connection with the motion for summary judgment raise a fact question of whether a “common enterprise” existed.10
We have earlier noted that the facts here are virtually identical to those in Milnarik, supra. One significant exception, however, is that the Milnarik court did not deal with the situation where the account is claimed to involve a pooling of funds, whereas in this case the plaintiffs allege that such misrepresentation occurred. The Milnarik court stated:
This characteristic of common enterprise is completely lacking in the present case. Even assuming that Nelson in fact solicited and collected money from numerous parties, no allegations are made that a common enterprise existed comprised of all people possessing discretionary account contracts with him. No claim is made that Nelson traded in a uniform manner for each of these accounts. Even if he had so uniformly traded, no pooling of funds for a common purpose is alleged. Nelson was apparently simply an agent for a number of separate and distinct principals, the plaintiffs being one such principal. The plaintiffs in no way can be viewed as having invested in a eom*225mon enterprise with other suppliers of venture capital.
Id. at 278. (emphasis added).
The evidentiary matter before the district court included a deposition of Lawrence McMann, a Merrill Lynch customer account executive, and a counter affidavit of James Olin, Manager of a Detroit-area Merrill Lynch office. Olin stated that regardless of what plaintiffs may have been told, their account was handled independently of others involved in the program, and was never used in a manner that would suggest a common enterprise with the companion accounts. McMann testified, however, that although the account may have been handled as suggested by Olin, the Currans were given a different description of the account. Essentially, McMann stated that the account offered to the Currans was unique: the trader acted as controller of a group of accounts thus allowing him to make buy/sell decisions on a broader basis and thereby control fluctuations in the market. This control was represented as a trading capability five times greater than for a separate account.
We do not view this tempting expectancy as elevating the trading account to the full dignity of a security. Essentially it remained an agency for hire. It is true that plaintiffs may have hoped that defendant’s control over a number of accounts would increase the agent’s clout in the market. The fact remains, however, that the plaintiffs always understood that their return would be based on a one-to-one vertical relationship with the trader. They knew there was no contractual tie to other accounts.
IV.
Merrill Lynch asserted in the district court that plaintiffs’ action was time-barred because the one year limitation period agreed upon in writing by the parties expired before the complaint was filed. The “Commodity Account Agreement” provided for submission of all disputes to arbitration within one year after the cause of action accrued.11
The accounts were opened April 5, 1973, and August 20, 1973. Plaintiffs claimed that they could not reasonably have known that defendant’s representations were false until April, 1974. Judge Thornton, however, declined to rule on Merrill Lynch’s claim that the action accrued more than one year prior to the April 5, 1976 filing of the complaint.
Merrill Lynch argues that absent a controlling statute to the contrary, a provision in a contract may validly limit the time for bringing an action for breach of contract to a period less than that prescribed in the general statute of limitations, at least if the shorter period is reasonable. See, e. g., Order of United Commercial Travelers of America v. Wolfe, 331 U.S. 586, 608, 67 S.Ct. 1355, 1365, 91 L.Ed. 1687 (1947).
Plaintiffs, however, assert that the one year limitation provision is tied to the arbitration clause in their discretionary trading account agreement, and that if arbitration is impermissible, the one year limitation also diés with it.12 We agree.
V.
Plaintiffs assert that arbitration is not a favored remedy with respect to commodity futures brokerage transactions, citing statutory and administrative limitations upon the enforcement of an agreement to arbitrate. Specifically, Section 5a(ll) of the *226Commodity Exchange Act, 7 U.S.C. § 7a(ll), as amended by the Commodity Futures Trading Commission Act of 1974, P.L. 93-463, 88 Stat. 1389, effective April 21,1975, provides that each contract market is required to:
(11) provide a fair and equitable procedure through arbitration or otherwise (such as by delegation to a registered futures association having rules providing for such procedures) for the settlement of customers’ claims and grievances against any member or employee thereof; Provided, That (i) the use of such procedure by a customer shall be voluntary, (ii) the procedure shall not be applicable to any claim in excess of $15,000, (iii) the procedure shall not result in any compulsory payment except as agreed upon between the parties.
(Emphasis added).
In 1976, the CFTC adopted regulations under Section 7a(ll) providing that no predispute arbitration agreement may be enforced unless the agreement is contained in a separate document executed by the customer and contains adequate warnings in large print.13 17 C.F.R. § 180.1 et seq. *227(1976). Although the cause of action here arose before the effective date of the CFTC Act, plaintiffs argue that the Act’s limitation upon arbitration should be retroactively applied. Plaintiffs urge that retroactive application is justified because the agreement here is an adhesion contract, forced upon plaintiffs and other like customers through unequal bargaining power and does not comply with the requirements of Section 180.3.
For its part, Merrill Lynch argues that the clause including the agreed limitation period is enforceable and that therefore the entire case should have been dismissed in the district court. Merrill Lynch contends that neither in their briefs nor in their argument to the district court did plaintiffs argue that CFTC Regulation § 180.3, 17 C.F.R. § 180.3, could or should be applied retroactively. That regulation did not become effective until November 29, 1976, months after the case had been briefed and argued to the district court. Therefore, we are urged to disregard this argument because it is raised for the first time on appeal. See Bannert v. American Can Co., 525 F.2d 104 (6th Cir.), cert. denied, 426 U.S. 942, 96 S.Ct. 2662, 49 L.Ed.2d 394 (1975); Schneider v. Electric Auto-Lite Co., 456 F.2d 366, 375 (6th Cir. 1972); Cashner v. United States Steel Corp., 327 F.2d 533 (6th Cir. 1964) (court refused to consider issue not raised until a supplemental appellate brief was filed). The Supreme Court, however, in Hormel v. Helvering, 312 U.S. 552, 556, 61 S.Ct. 719, 721, 85 L.Ed. 1037 (1941), stated:
There may always be exceptional cases or particular circumstances which will prompt a reviewing or appellate court, where injustice might otherwise result, to consider questions of law which were neither pressed nor passed upon by the court or administrative agency below.
In their supplemental brief, plaintiffs assert that Ames v. Merrill Lynch, Pierce, Fenner & Smith, 567 F.2d 1174 (2d Cir. 1977), supports the retroactive application of CFTC Reg. § 180.3 to bar arbitration here, and in so doing, also negates the one year limitation period written into it. In Ames, plaintiff signed the same standard form Merrill Lynch agreement as involved in this case. The plaintiff opposed a stay of arbitration on the ground that 17 C.F.R. § 180.3, which became effective on November 29, 1976, after the agreement was entered into, should be applied retroactively to render the arbitration agreement null and void. The Second Circuit agreed that the CFTC intended section 180.3 to be given retroactive effect and further observed that:
A court must apply the law as it exists at the time of its decision, even where the law has changed during the pendency of the action, unless the statute or legislative history reveals an intention of prospective application only, or retroactive application would lead to “manifest injustice.” Bradley v. Richmond School Board, 416 U.S. 696, 711, 94 S.Ct. 2006, 2016, 40 L.Ed.2d 476 (1974). In applying this principle to the instant case, we are called upon to determine: (1) whether the Commission had the authority to apply the provisions of § 180.3 to all arbitration agreements; (2) whether the Commission intended the application of the regulation *228to arbitration agreements antedating the regulation; and (3) whether, given the authority and intention to make the regulation effective as to antedated agreements, the particular circumstance that the dispute arose before the effective date of the regulation nevertheless precludes its application.
Id. at 1177.
Before making its determination, the Ames court traced the evolution of Section 180.3. The Commodity Exchange Act, 7 U.S.C. § 7a(ll), required only that each contract market provide a “fair and equitable procedure through arbitration or otherwise” for settlement of claims up to $15,000, and that the use of such procedure be voluntary on the part of the customer. Neither arbitration of claims over $15,000 nor arbitration outside the contract market were mentioned in the Act. The Commission, however, determined that arbitration outside the literal scope of the Act should be regulated, and under provisions in the Act giving the Commission authority “to make and promulgate such rules and regulations as are necessary to effectuate any of •the provisions or to accomplish any of the purposes of the act,” 7 U.S.C. § 12a(5), the Commission promulgated section 180.3.
Initial proposals submitted by the Commission sought to bar any agreement to arbitrate future disputes, but provided that grievances arising out of agreements actually entered into prior to the adoption of the regulations should be exempted. Later, the Commission decided that pre-dispute agreements would be tolerated, but only under conditions designed to insure that arbitration was truly voluntary. Also, the exemption for agreements antedating the regulation was withdrawn. As stated by the Ames court, “[ijnstead, the thrust was to include even pre-existing arbitration agreements in the new order of things.” Id. at 1178. Therefore, in making the final regulation effective on November 29, 1976, the Commission announced that “on the effective date of proposed § 180.3(b), all pre-dispute arbitration agreements that do not satisfy the conditions set forth in the proposed rule will be null and void, including those heretofore signed by customers.” 41 Fed.Reg. 42,944 (Sept. 29, 1976). The announcement made no mention of the treatment to be accorded disputes already in existence. On this basis, the Ames court held that “§ 180.3 fairly read should apply to all arbitration agreements existing at the effective date of the regulation.” Id. at 1179.14 See also Tamari v. Bache & Co. (Lebanon) S.A.L., 565 F.2d 1194 (7th Cir. 1977), cert. denied, (Swygert, J. dissenting); 435 U.S. 905, 98 S.Ct. 1450, 55 L.Ed.2d 495 (1978); Rothberg v. Loeb, Rhoades & Co., 445 F.Supp. 1336 (S.D.N.Y.1978); Milani v. Conticommodity Services, Inc., 462 F.Supp. 405, 406-07 (N.D.Cal.1976).
The retroactive effect of an alteration in a regulatory scheme generally depends upon whether it affects litigation at a point which causes a result so unfair and inequitable that it is unconstitutional. Plaintiffs here sought equitable relief from the arbitration clause in their customer commodity account agreement at an early stage of the litigation, and no surprise or other unfairness is apparent upon the record. Under these circumstances we do not find that retroactive application of Regulation § 180.3 would result in manifest injustice.
Further, we note that the plaintiff in Ames appealed from a district court order compelling arbitration and staying trial of his action, and therefore, sought equitable relief from the effect of a similar arbitration agreement at the same stage of the *229proceedings as the plaintiffs in the instant case.15 In support of its result, the Ames court stated:
Shortly after its creation, in 1975, the Commission undertook an examination of the use of arbitration in the futures industry. It learned that arbitration was frequently conducted not under the auspices of the contract markets regulated by the Commission but through arbitration sponsored by the New York Stock Exchange or other securities-oriented organizations. It also became apparent that in many cases arbitration was not undertaken voluntarily by customers, but that customers were compelled to agree to pre-dispute arbitration clauses as a precondition to doing business. Indeed, this practice was found to be so prevalent that a customer might effectively be frozen out of the futures market if he refused to execute a predispute agreement. 41 Fed.Reg. 27,526 (July 2, 1976); 41 Fed. Reg. 42,945 (Sept. 29, 1976).
The Commission received written comments and took oral testimony on March 5, 1976. At this hearing conducted by the Commission, representatives both of Merrill Lynch and Shearson Hayden Stone conceded that a customer could not do futures business with the firm if he refused to sign a predispute arbitration agreement. Commodity Futures Trading Comm’n, Oral Hearing on Arbitration and Other Dispute Settlement Procedures 32-34, 37, 82-98. (March 5, 1976); see generally 41 Fed.Reg. 42,945 (Sept. 29, 1976).
Id. at 1178. In response to its fact-finding, the Commission, in announcing the effective date of the regulation, reiterated the nullity of all pre-dispute arbitration agreements not complying with the conditions of Section 180.3 but did not mention any exemption for existing disputes. 41 Fed.Reg. 42,942 — 44 (Sept. 29, 1976). As further noted in Ames, “any such exemption would hardly conform to the notion, stated by the Commission itself, that customers who had entered into agreements before adoption of the regulation needed and were entitled to the protections of the rule no less than those customers who signed agreements after November 29, 1976.” Id. at 1177.
Our determination that Section 180.3 should be retroactively applied to invalidate the arbitration agreement in this case compels the further conclusion that the one year limitation period provided for therein is also inapplicable. The one year limitation was expressly contingent upon the institution of arbitration proceedings and the language of the agreement nowhere extends to any residual and underlying court action which may otherwise exist.
Accordingly, the order compelling arbitration and staying this action with respect to plaintiffs’ commodity claims must be reversed and remanded to the district court.
VI.
Merrill Lynch has acknowledged that it did not consider the partial summary judgment in its favor, from which this appeal is *230taken,'to have extended to or to have affected in any way the plaintiffs’ claims under the Commodity Exchange Act (CEA).16 Nevertheless, affirmance of the partial summary judgment and consequent remand to the district court for proceedings on the balance of the case necessarily raises the further question whether the federal district court has jurisdiction to entertain the remaining claims arising under the Commodity Exchange Act.17
Although the CEA does not expressly provide for a private right of action to recover damages, an implied right of action was generally thought to exist prior to the 1974 amendment of the Act.18 Consistent with this view, no issue concerning the continuing validity of the implied right of action was raised in the court below, nor in this appeal.19 Nevertheless, to provide direction to the district court upon remand and to avoid further delay in this already protracted litigation, we review this issue and specifically agree that an implied private right of action survived the 1974 amendments to the Act.20
*231The original Commodity Exchange Act of 1936 established a scheme for regulating trading in agricultural commodities futures based primarily on the concept of self-regulation. The chief means of enforcement of the Act emanated from the Commission’s regulations and the rules of each Exchange, to which the courts added an implied private right of action. The increasing effect of commodities trading on the nation’s economy, and significant escalations in annual trading volume, also gave rise to increased instances of fraud and manipulation. By 1974, Congress became aware that the system of self-regulation had decreased in effectiveness and sought to buttress the enforcement of the CEA safeguards.21
In 1974 Congress amended the Commodity Exchange Act to create the Commodity Futures Trading Commission and established an administrative procedure under which violations of any rule, provision, or regulation of the Act could be redressed by the commencement of an administrative proceeding before the CFTC to recover reparations.22 7 U.S.C. § 18(e). Reparations procedures may be initiated against futures commission merchants, floor brokers, commodity trading advisers and commodity pool operators, but not against the contract markets (exchanges). A judgment rendered in a reparations proceeding remains subject to appeal in the courts of appeal and is enforceable in the district courts. Additionally, the 1974 amendments grant the CFTC plenary power over futures commission merchants and contract markets.23 The creation of the CFTC was to provide a “strong Federal regulatory umbrella” to support the regulatory efforts of the exchanges in curbing unfair trading practices by providing public enforcement measures at both the exchange and individual level. H.R.Rep.No. 975, 93d Cong., 2d Sess. 48 (1974).
Although the 1974 amendments represented a thorough revision of congressional regulation over the commodities futures trading industry, the Act did not speak to *232the continuing validity of the pre-existing private right of action. We believe the legislative history of the CFTC Act, however, indicates that Congress intended to extend further protection to the exchange customer, rather than to extinguish existing forms of protection. This observation is bolstered by the fact that Congress recognized self-regulation as a “commendable and noble concept and useful in such a complex atmosphere as that which surrounds futures trading.” H.R.Rep.No. 975, 93d Cong., 2d Sess. 48 (1974).
In addition to providing a more comprehensive regulatory scheme, it appears that Congress was motivated by a desire to clarify the jurisdictional dispute developing between the Commodity Exchange Commission and the Securities Exchange Commission with regard to commodities regulation under section 2 of the 1974 Act. Congress, therefore, vested exclusive jurisdiction over commodities futures trading with the CFTC. 7 U.S.C. § 4a. See Smith v. Groover, 468 F.Supp. 105 (N.D.Ill.1979); R. J. Hereley & Son Co. v. Stotler & Co., 466 F.Supp. 345 (N.D.Ill.1979); Hofmayer v. Dean Witter & Co., 459 F.Supp. 733 (N.D.Cal.1978). The exclusive jurisdiction provision, however, should not be construed as extinguishing the pre-existing private right of action by implication since the thrust of the provision was to ensure that regulatory bodies other than the CFTC would not interfere with the orderly development and enforcement of commodities regulation. H.R.Rep.No. 93-975, 93 Cong., 2d Sess. 28 (1974). This result is further shown by additional language in the Act in which Congress provided that “nothing in this section shall supersede or limit the jurisdiction conferred on the courts of the United States or any State”. 7 U.S.C. § 2. Further, it is apparent from the following statement that Congress intended to supplement existing remedies, rather than create a substitute for them:
The vesting in the Commission of the authority to have administrative law judges and apply a broad spectrum of civil and criminal penalties is likewise not intended to interfere with the courts in any way. It is hoped that giving the Commission this authority will somewhat lighten the burden upon the courts, but the entire appeal process and the right of final determination by the courts are expressly preserved, (emphasis added).
Remarks of Senator Talmadge, 120 Cong. Rec. 30459 (1974).24
The CFTC has interpreted the Act as implicitly authorizing private actions, and asserts that the right must be presumed to have survived the 1974 amendments unless Congress explicitly abolished the private remedy in enacting the amendments. Statement of CFTC Concerning Referral of Private Litigation Under the Doctrine of Primary Jurisdiction. 41 Fed.Reg. 18471 (May 5, 1976). See also Smith v. Groover, 468 F.Supp. 105 (N.D.Ill.1979) (amicus brief submitted by CFTC).
The judicial canon of construction which allows the court to grant considerable deference to the interpretation of a statute by an agency charged with its administration also supports the conclusion that the 1974 act did not preclude a private right of action. See United States v. Consumer Life Ins. Co., 430 U.S. 725, 752, 97 S.Ct. 1440, 1454, 52 L.Ed.2d 4 (1977); NLRB v. Boeing Co., 412 U.S. 67, 75, 93 S.Ct. 1952, 1957, 36 L.Ed.2d 771 (1973). However, the Supreme Court indicated in Piper v. Chris-Craft Industries, Inc., 430 U.S. 1, 41, n. 27, 97 S.Ct. 926, 949 n. 27, 51 L.Ed.2d 124 (1976), that the administrative deference rule is not applicable where the narrow legal issue is whether a cause of action should be implied in favor of a particular class of litigants by judicial interpretation. See also National Super Spuds, Inc. v. New York Mercantile Exchange, 470 F.Supp. 1256 (S.D.N.Y.1979).
*233We admit that a recognized private right of action need not be re-examined every time the statutory scheme from which it is implied is altered. Nevertheless case law since the 1974 amendments has raised at least some uncertainty as to the continued vitality of the implied right, especially when analyzed in light of Cort v. Ash, 422 U.S. 66, 95 S.Ct. 2080, 45 L.Ed.2d 26 (1975).25 See also Smith v. Groover, 468 F.Supp. 105, 112 (N.D.Ill.1979).
The Supreme Court established a four-part test in Cort to determine whether Congress intended a private remedy to be implied from legislation which created enforceable rights but remained silent as to the form of remedy. Since the 1974 amendments, the implied right of action inquiry has centered primarily on the issues of Congress’ legislative intent in enacting the 1974 amendments and the consistency of the statutory scheme with the Commodity Exchange Act.
In Cort v. Ash, supra, the Court delineated four relevant factors to determine whether a private right of action may be implied under a federal statute:
First, is the plaintiff “one of the class for whose especial benefit the statute was enacted,” . . . that is, does the statute create a federal right in favor of the plaintiff? Second, is there any indication of legislative intent, explicit or implicit, either to create such a remedy or to deny one? . . Third, is it consistent with the underlying purposes of the legislative scheme to imply such a remedy for the plaintiff? . . . And finally, is the cause of action one traditionally relegated to state law, in an area basically the concern of the States, so that it would be inappropriate to infer a cause of action based solely on federal law?
Id. 422 U.S. at 78, 95 S.Ct. at 2088. See also Transamerica Mortgage Advisors, Inc. v. Lewis, 444 U.S. 11, 16, 100 S.Ct. 242, 245, 62 L.Ed.2d 146 (1979); Touche Ross & Co. v. Redington, 442 U.S. 560, 99 S.Ct. 2479, 61 L.Ed.2d 82 (1979); Cannon v. University of Chicago, 441 U.S. 677, 99 S.Ct. 1946, 60 L.Ed.2d 560 (1979); Piper v. Chris-Craft Industries, 430 U.S. 1, 37, 97 S.Ct. 926, 947, 51 L.Ed.2d 124 (1976).
The first element is easily satisfied. Clearly investors in the commodities markets are within the class “for whose especial benefit the statute was enacted.” The legislative history of the 1974 amendments shows that the primary purpose was to protect against manipulation of markets and to protect individuals who desire to participate in futures market trading.26 7 U.S.C. § 6b. See, e. g., Smith v. Groover, 468 F.Supp. 105 *234(N.D.Ill.1979); Berman v. Bache, Halsey, Stuart, Shields, Inc., 467 F.Supp. 311, 322 (S.D.Ohio 1979); National Super Spuds, Inc. v. New York Mercantile Exchange, 470 F.Supp. 1256 (S.D.N.Y.1979). But see Liang v. Hunt, 477 F.Supp. 891 (N.D.Ill.1979) (distinguished claims involving excessive speculation and price manipulation in violation of statutory limits from fraud actions).
The second factor, whether there is any explicit or implicit indication of legislative intent to grant or deny a private right of action, also supports the implication of a private action under the CEA. The legislative history of the 1974 amendments indicates that Congress was aware, of the fact that the federal courts had implied the existence of a private right of action under the CEA.27 Further, the “exclusive jurisdiction” provision of the CFTC, 7 U.S.C. § 2 (amended),28 does not indicate an intention to abolish the pre-1974 implied right of action, as previously noted, particularly since Congress included in Section 2(a)(1) that “nothing in this section shall supersede or limit the jurisdiction conferred on the courts of the United States or any State.” The Conference Committee which adopted the language offered by the Senate explained in its report that the purpose of the amendment was “to make clear that nothing in the Act would supersede or limit the jurisdiction presently conferred on courts of the United States or any State.” 120 Cong. Rec. 34997 (October 10, 1974); 120 Cong. Rec. 34737 (October 9,1974). Therefore, we believe that the reparations procedure established in the 1974 amendments, as construed by the relevant legislative history, shows that Congress intended the administrative remedy to serve “as a supplement to, rather than a substitute for, the existing private right of action.” Smith v. Groover, supra, 468 F.Supp. at 113-14. But see National Super Spuds, supra, 470 F.Supp. at 1260; Berman, supra, 467 F.Supp. at 322.29
The third element of Cort, whether the implication of a private right of action would be consistent with the underlying purposes of the Act is also met in this case. As stated in Smith v. Groover:
[T]he continued existence of a private right of action for aggrieved investors is perfectly compatible with the language and purpose of the CFTCA. Affording
*235injured commodities futures buyers a multiplicity of remedies against futures traders will deter the sort of manipulative pricing practices alleged to have been committed by defendants. As shown above, Congress intended the reparations proceedings in the CFTC to constitute an alternative to the more time-consuming, cumbersome, expensive and formal adjudication of private claims in federal or state courts. The availability of a variety of remedies thus harmonizes well with the Congressional intent to protect the public from fraud and price manipulation.
Recent administrative interpretations of the CFTCA also demonstrate the compatibility of a private right of action with the purposes of the Act. The CFTC has consistently interpreted the reparations section as permitting commodity customers an election of forums in which to pursue their claims. See 41 Fed.Reg. 3994 (1976); 41 Fed.Reg. 18472 at n. 5 (1976) ; Stucki v. American Options Corp., CCH Comm.Fut.L.Rep. ¶ 20,559 at 22,283 (CFTC 1978). The CFTC will not even entertain a reparation claim if civil court litigation involving the same facts and parties has been instituted. 17 C.F.R. § 12.21(a)(7) (1977). We recognize that “. . . the consistent construction of a statute ‘by the agency charged with its enforcement is entitled to great deference by the courts.’ ” United States v. Consumer Life Insurance Co., 430 U.S. 725, 752, 97 S.Ct. 1440, 1454, 52 L.Ed.2d 4 (1977) , quoting from NLRB v. Boeing Co., 412 U.S. 67, 75, 93 S.Ct. 1952 [1957], 36 L.Ed.2d 752 (1973); see also, Chemehuevi Tribe of Indians v. Federal Power Commission, 420 U.S. 395, 409-10, 95 S.Ct. 1066 [1075], 43 L.Ed.2d 279 (1975). 468 F.Supp. at 115. But see National Super Spuds, supra, 470 F.Supp. at 1260; Berman, supra, 467 F.Supp. at 322-23.
The fourth factor, whether the implication of a private right would infringe on an area of state concern is not crucial here since Cort v. Ash, supra, 422 U.S. at 84-85, 95 S.Ct. at 2091, indicates that a court should imply a private remedy when relegation to state law would frustrate the purpose of the federal statute. This factor favors the implication of a private right of action since the regulation of commodity futures trading is essentially a matter of federal concern.
Our analysis of the effect of the 1974 amendments to the Commodity Exchange Act, within the framework of Cort v. Ash, persuades us that the amendments did not impair the validity of the pre-existing implied private right of action. Rather, Congress appears to have armed aggrieved investors with a supplementary remedy in creating the reparations procedures to be followed under CFTC authority.
Finally our research persuades us that the primary jurisdiction doctrine should not be invoked here to compel exhaustion of the administrative reparations procedures before instituting a private action.30
The primary jurisdiction doctrine is intended to ensure that private suits will not interfere with the orderly development of precedent or exercise of discretion by an agency. The principal reason for invoking the doctrine in an action arising under the CEA would be to avoid interfering with the CFTC’s administration of the regulatory scheme. The preservation of an implied right of action does not, of course, interfere *236with the rulemaking power conferred upon the CFTC by Congress or with the opportunity of the Commission to apply its expertise through that power to complement the orderly development of precedent and procedure.
In determining whether to invoke the primary jurisdiction doctrine the courts must balance the need for special expertise and the extent to which administrative relief is available. Eluska v. Andrus, 587 F.2d 996, 999 (9th Cir. 1978). In a case where the primary issues involve allegations of fraud rather than a complex manipulative scheme, the special expertise of the CFTC is not a prerequisite to a just resolution. The facts here are far different from those which prompted reversal and remand in Chicago Mercantile Exchange v. Deaktor, 414 U.S. 113, 94 S.Ct. 466, 38 L.Ed.2d 344 (1973). There the district court had refused a stay of an action against the Chicago Mercantile Exchange charging antitrust and Commodity Exchange Act violations through manipulation of the futures market in fresh eggs. The stay was requested to afford the Commodity Exchange Commission an opportunity to determine whether the conduct under scrutiny violated the CEA or its own rules. The Supreme Court in Deaktor observed, as it had in Ricci v. Chicago Mercantile Exchange, 409 U.S. 289, 93 S.Ct. 573, 34 L.Ed.2d 525 (1973), that the trial court “should avail itself of the abilities of the Commission to unravel the intricate and technical facts of the commodity industry and to arrive at some judgment as to whether the Exchange had conducted itself in compliance with the law.” Id. 414 U.S. at 115, 94 S.Ct. at 467. It therefore observed that claims “should be routed in the first instance to the agency whose administrative functions appear to encompass adjudication of the kind of substantive claims made against the [defendant].” Id. at 115, 94 S.Ct. at 467. See also Jones v. B. C. Christopher & Co., 466 F.Supp. 213 (D.Kan.1979). No such intricate and technical facts are involved here. On the contrary, the CFTC has itself noted that the application of primary jurisdiction is “rarely, if ever” appropriate for claims within “private litigation seeking damages for alleged violations of provisions of the Act,” and that “[t]he issues raised by a particular fraudulent scheme, however complicated, are entirely within the conventional ability of the courts.” Fed.Reg.Doc. 76-12906 (May 3, 1976). See also Jones, supra, at 222-23; Shearson Hayden Stone, Inc. v. Lumber Merchants, Inc., 423 F.Supp. 559 (S.D.Fla.1976).
CONCLUSION
Judge Phillips’ dissent accurately calls attention to a number of Supreme Court decisions which, we agree, indicate a tendency to be more restrictive in implying a private right of action. While we recognize potential merit in this view, especially in light of the comprehensive administrative scheme embodied in the 1974 amendments, we are not persuaded that Congress intended to extinguish the pre-existing private right of action which had been generally acknowledged to exist under the Act. See note 18, supra. What we have done here, in our view, is to preserve the general concept of a private right of action and to provide for its continuing development, not under the securities laws generally, but under those laws of Congress which are more particularly related to the commodities market. This approach provides greater sensitivity to the specialized concerns of that area of commercial life, appears consistent with congressional intent and also allows for the development of a private right of action similar to the valuable body of law that has grown under Section 10 of the Securities Exchange Act and Rule 10b — 5. It is arguable, of course, that some particular actions or claims may require initial submission to the Commodities Futures Trading Commission under the primary jurisdiction doctrine. Suffice it to say, however, that such problems do not exist here and can be properly addressed as they arise, on a case-by-case basis.
Accordingly, the partial summary judgment entered by the district court denying plaintiffs’ relief on their claims under fed*237eral securities law is affirmed. However, that part of the order which stays plaintiffs’ fraud claims under the Commodity Exchange Act is reversed and remanded to the district court for proceedings consistent with this opinion.
. An order staying a pending action until the case is submitted to arbitration is appealable under 28 U.S.C. § 1292(a)(1) if the underlying action, as here, is legal in nature. See Mansbach v. Prescott, Ball & Turben, 598 F.2d 1017, *2191022 (6th Cir. 1979); 9 Moore’s Federal Practice fl 110.20[3].
. In Kelley v. Carr (6th Cir. 1980) (decided March —, 1980 File No. 78-1091/2), our court noted that the federal courts are in conflict over the continuing validity of a private implied right of action under the Commodity Exchange Act, following the 1974 amendments to the Act. The Kelley court, however, found it unnecessary to resolve the issue under the circumstances presented in that case. Id. at

The term “security” means any note, stock, treasury stock, bond, debenture, evidence of indebtedness, certificate of interest or participation in any profit-sharing agreement, collateral-trust certificate, preorganization certificate or subscription, transferable share, investment contract, voting-trust certificate, certificate of deposit for a security, fractional undivided interest in oil, gas, or other mineral rights, or, in general, any interest or instrument commonly known as a “security,” or any certificate of interest or participation in, temporary or interim certificates for, receipt for, guarantee of, or warrant or right to subscribe to or purchase, any of the foregoing.

Bache, Halsey, Stuart, Shields Co., 467 F.Supp. 311 (S.D.Ohio 1979); Arnold v. Bache & Co., 377 F.Supp. 61 (M.D.Pa. 1973); Stuckey v. duPont Glore Forgan, Inc., 59 F.R.D. 129, 131 (N.D.Cal.1973).
. It is interesting to note that the SEC had argued unsuccessfully before the district court in Continental Commodities, supra, that “trading in discretionary commodities accounts engaged in by Continental Commodities fell within the ambit of the term security, as defined by the Securities Act of 1933 and the Securities Exchange Act of 1934.” 497 F.2d at 520.
. In Brodt v. Bache & Co., Inc., 595 F.2d 459 (9th Cir. 1979), the Ninth Circuit recognized its prevailing definition of “common enterprise” as one in which the fortunes of the investor are interwoven with and dependent upon the efforts and success of those seeking the investment or of third persons. However, the court noted its inconsistency with Milnarik’s strict pooling requirement for discretionary commodity accounts. The Brodt court then distinguished a discretionary commodity account from its general test by stating:
[I]n the instant case, the investor’s return, while specifically determined by the commodities market, is also clearly affected by the expertise of the person doing the trading. . the success or failure of Bache as a brokerage house does not correlate with individual investor profit or loss. On the contrary, Bache could reap large commissions for itself and be characterized as successful, while the individual accounts could be wiped out. Here, strong efforts by Bache will not guarantee a return nor will Bache’s success necessarily mean a corresponding success for Brodt. Weak efforts or failure by Bache will deprive Brodt of potential gains but will not necessarily mean that he will suffer serious
losses. Thus, since there is no direct correlation on either the success or failure side, we hold that there is no common enterprise between Bache and Brodt.
Id. at 461. Specifically, Brodt concluded that “merely furnishing investment counsel to another for a commission, even when done by way of a discretionary commodities account, does not amount to a common enterprise.” Id. at 462.

See also Consolo v. Hornblower & *224Weeks-Hemphill, Noyes, Inc., 436 F.Supp. 447 (N.D.Ohio 1976), where the court determined that a non -discretionary trading account in a commodities future was not an investment contract under the securities laws. However, in defining what is required to find an investment contract the Consolo court stated that a contract situation involving only two persons, i. e., the investor and his stock broker, does not admit of the common enterprise which is essential to the existence of an investment contract. Id. at 452.
. Upon summary judgment the inferences to be drawn from the underlying facts contained in supplemental materials must be viewed in a light most favorable to the party opposing the motion, United States v. Diebold, 369 U.S. 654, 655, 82 S.Ct. 993, 994, 8 L.Ed.2d 176 (1962), and facts which are asserted, if supported by evidentiary material, must be accepted as true. Day v. United Auto Aerospace Agric. Workers, 466 F.2d 83 (6th Cir. 1972).
. “Arbitration must be commenced within one year after the cause of action accrued by service upon the other of a written demand for arbitration or a written notice of intention to arbitrate, naming therein the arbitration tribunal.”
. Plaintiffs’ also assert that the Supreme Court in Wilko v. Swan, 346 U.S. 427, 74 S.Ct. 182, 98 L.Ed. 168 (1953), determined that an agreement to arbitrate cannot preclude an aggrieved purchaser of a “security” from seeking a judicial remedy under section 14 of the Securities Act of 1933. Further, the Wilko principle has been held equally applicable to claims under the Securities Exchange Act of 1934. However, due to our finding that the discretionary commodity account involved in this case is not a security, this argument is inapplicable.
. 17 C.F.R. § 180.3 states:
Voluntary procedure and compulsory payments.
(a) The use by customers of the dispute settlement procedures established by contract markets pursuant to the Act or this Part or of the arbitration or other dispute settlement procedures specified in an agreement under paragraph (b)(3) of this section shall be voluntary. The procedures so established shall prohibit any agreement or understanding pursuant to which customers of members of the contract market agree to submit claims or grievances for settlement under said procedures prior to the time when the claim or grievance arose, except in accordance with paragraph (b) of this section.
(b) No futures commission merchant, floor broker or associated person shall enter into any agreement or understanding with a customer in which the customer agrees, prior to the time the claim or grievance arises, to submit such claim or grievance to any settlement procedure except as follows: ,
(1) Signing the agreement must not be made a condition for the customer'to utilize the services offered by the future commission merchant, floor broker or associated person;
(2) If the agreement is contained as a clause or clauses of a broader agreement, the customer must separately endorse the clause or clauses containing the cautionary language and other provisions specified in this section;
(3) The agreement may not require the customer to waive the right to seek reparations under section 14 of the Act and Part 12 of these regulations. Accordingly, the customer must be advised in writing that he or she may seek reparations under section 14 of the Act by an election made within 45 days after the futures commission merchant, floor broker or associated person notifies the customer that arbitration will be demanded under the agreement. This notice must be given at the time when the futures commission merchant, floor broker or associated person notifies the customer of an intention to arbitrate. The customer must also be advised that if he or she seeks reparations under section 14 of the Act and the Commission declines to institute reparation proceedings, the claim or grievance will be subject to the preexisting arbitration agreement and must also be advised that aspects of the claims or grievances that are not subject to the reparations procedure (i. e. do not constitute a violation of the Act or rules thereunder) may be required to be submitted to the arbitration or other dispute settlement procedure set forth in the preexisting arbitration agreement.
(4) The customer agreement must contain cautionary language, printed in large boldface type, to the following effect:
WHILE THE COMMODITY FUTURES TRADING COMMISSION (CFTC) RECOGNIZES THE BENEFITS OF SETTLING DISPUTES BY ARBITRATION, IT REQUIRES THAT YOUR CONSENT TO SUCH AN AGREEMENT BE VOLUNTARY. YOU NEED NOT SIGN THIS AGREEMENT TO OPEN AN ACCOUNT WITH [name]. See 17 CFR 180.1-180.6.
BY SIGNING THIS AGREEMENT, YOU MAY BE WAIVING YOUR RIGHT TO SUE IN A COURT OF LAW, BUT YOU ARE NOT WAIVING YOUR RIGHT TO ELECT AT A LATER DATE TO PROCEED PURSUANT TO SECTION 14 OF THE COMMODITY EXCHANGE ACT TO SEEK DAMAGES SUSTAINED AS A RESULT OF A VIOLATION OF THE ACT, IN THE EVENT A DISPUTÉ ARISES, YOU WILL BE NOTIFIED IF [name] INTENDS TO SUBMIT THE DISPUTE TO ARBITRATION, IF YOU BELIEVE A VIOLATION OF THE COMMODITY EXCHANGE ACT IS INVOLVED AND IF YOU PREFER TO REQUEST A SECTION 14 “REPARATIONS” PROCEEDING BEFORE THE CFTC, YOU WILL STILL HAVE 45 DAYS IN WHICH TO MAKE THAT ELECTION.
(5) If the agreement specifies a forum for settlement other than a procedure estab*227lished pursuant to section 5a(ll) of the Act or this Part, the procedures of such forum must comply with the requirements of § 180.-5.
(c) The procedure established by a contract market pursuant to section 5a(ll) of the Act or this Part may require parties utilizing such procedure to agree, under applicable state law, submission agreement or otherwise, to be bound by an award rendered in the procedure, provided that the agreement to submit the claim or grievance to the procedure was made in accordance with paragraph (b) of this section or that the agreement to submit the claim or grievance was made after the claim or grievance arose. Any award so rendered shall be enforceable in accordance with applicable law.
(d) The procedure established by a contract market pursuant to the Act or this Part shall not establish any reasonably short limitation period foreclosing submission of customers’ claim or grievances or counterclaims (permitted by § 180.4 or this Part) by contract market members or employees thereof. (7 U.S.C. 7a(ll), 12a (Supp. V, 1975)) [41 FR 42946, Sept. 29, 1976, as amended at 42 FR 3433, Jan. 18, 1977]

Apparently Judge Meskill agreed with the basic portent of the regulation but thought that application to disputes already in existence was extremely unfair. He perceived no problems in allowing retroactive effect “to the extent necessary to bring about an immediate change in existing contracts without unnecessarily cutting off accrued rights.” Id. at 1182-83.
. We note that in Arkoosh v. Dean Witter & Co., 571 F.2d 437 (8th Cir. 1978), plaintiff contended that section 180.3 rendered invalid the arbitration clause in his customer agreement. The claim, however, was not made until after the district court had issued a stay of arbitration, and an arbitration award in defendant’s favor had been granted. The Arkoosh court recognized the holding in Ames v. Merrill Lynch, Pierce, Fenner & Smith, Inc., 567 F.2d 1174, 1179 (2d Cir. 1977), and in fact concurred by stating: “[t]he regulation voided all existing pre-dispute arbitration agreements in contracts for the purchase of commodities unless certain conditions are met.” Id. at 438. Further, the Arkoosh court recognized that generally “a court is to apply the law in effect at the time it renders its decision, unless doing so would result in manifest injustice . . .” 571 F.2d at 438. (citations deleted). Within this context, the Eighth Circuit noted the district court’s ruling that the chronological sequence demonstrated that plaintiff had ample time after the effective date of Section 180.3, and before the submission to arbitration, to urge the Court to reconsider its interpretation of the Customer Agreement. The defendant, having obtained the arbitration award, would suffer substantial injustice if the case was reopened, since plaintiff’s assertion of his rights under the new regulation was untimely. Otherwise, the plaintiff could play it both ways, and seek relief to have arbitration set aside only if an unfavorable award is ordered.
. We construe the order of dismissal entered by the district court to grant only the relief requested by defendant’s motion to dismiss, which related only to those allegations of the complaint purporting to state claims under the Securities Act of 1933 and the Securities Exchange Act of 1934. However, we view the pleadings and allegations in plaintiffs’ complaint purporting to state a claim under the Commodities Exchange Act, 7 U.S.C. § 1, et seq., as unimpaired by the district court’s order of dismissal as, indeed, are the pendent state claims.
. In Alexander v. Aero Lodge No. 735, 565 F.2d 1364 (6th Cir. 1977), cert. denied, 436 U.S. 946, 98 S.Ct. 2849, 56 L.Ed.2d 787 (1978), we recognized that a court of appeals should ordinarily limit its review of an interlocutory order to the narrow question of whether the district court abused its discretion and refrain from intruding into the merits of the case only to the extent necessary to decide that issue. We determined, however, that the rule is one of orderly judicial administration and not a limit on jurisdictional power. Therefore, it is generally recognized that a court possesses the jurisdictional power on the appeal of an interlocutory order under 28 U.S.C. § 1292(a)(1) to reach and decide other aspects of the order which would not be independently reviewable by interlocutory appeal. Id. at 1370. See also Mansbach v. Prescott, Ball & Turben, 598 F.2d 1017, 1022 (6th Cir. 1979) (interlocutory order staying a pending action submitted to arbitration is appealable under section 1292(a)(1) if the underlying action is legal in nature).
. See, e. g., Deaktor v. L. D. Schreiber & Co., 479 F.2d 529 (7th Cir.), rev’d on other grounds sub nom. Chicago Mercantile Exchange v. Deaktor, 414 U.S. 113, 94 S.Ct. 466, 38 L.Ed.2d 344 (1973) (antimanipulation provision of 7 U.S.C. § 13b); Booth v. Peavey Co. Commodity Services, 430 F.2d 132 (8th Cir. 1970) (7 U.S.C. § 6b anti-fraud provision); Goodman v. H. Hentz & Co., 265 F.Supp. 440 (N.D.Ill.1967) (§ 6b); United Egg Producers v. Bauer International Corp., 311 F.Supp. 1375 (S.D.N.Y.1970) (§ 13b); McCurnin v. Kohlmeyer & Co., 340 F.Supp. 1338 (E.D.La.1972) (§ 6b); Johnson v. Arthur Espey, Shearson, Hammill & Co., 341 F.Supp. 764 (S.D.N.Y.1972) (§ 6b); Arnold v. Bache & Co., Inc., 377 F.Supp. 61 (M.D.Pa.1973) (§ 6b).
. Plaintiffs allege that this cause of action arose in 1974, prior to the amendment of the Commodity Exchange Act. At that time it was generally held that a private cause of action existed under the Act. See note 18, supra. In 1974 Congress amended the Commodity Exchange Act, 7 U.S.C. § 1, et seq., effective in 1975, to create a comprehensive regulatory procedure for the processing of complaints within the newly-established Commodity Futures Trading Commission (CFTC). This action was filed on April 5, 1976. Since the amendment of the CEA the courts have adopted contrary views with regard to the continuing validity of the pre-1974 implied right of action. Although the parties have not raised this issue on appeal, it is well established that “a court is to apply the law in effect at the time it renders its decision, unless doing so would result in manifest injustice or there is statutory direction or legislative history to the contrary.” Bradley v. Richmond School Board, 416 U.S. 696, 711, 94 S.Ct. 2006, 2016, 40 L.Ed.2d 476 (1974). See also Cort v. Ash, 422 U.S. 66, 74, 95 S.Ct. 2080, 2086, 45 L.Ed.2d 26 (1975); Thorpe v. Housing Authority of the City of Durham, 393 U.S. 268, 89 S.Ct. 518, 21 L.Ed.2d 474 (1969); Bush v. State Industries Co., 599 F.2d 780 (6th Cir. 1979); Weisenberger v. Huecker, 593 F.2d 49 (6th Cir.), cert. denied, 444 U.S. 880, 100 S.Ct. 170, 62 L.Ed.2d 110 (1979).
. In determining to proceed to the merits of this issue we recognize that in Burks v. Lasker, 441 U.S. 471, 99 S.Ct. 1831, 1836 n. 5, 60 L.Ed.2d 404 (1979), the Supreme Court stated that “the question of whether a cause of action exists is not a question of jurisdiction, and therefore may be assumed without being decided.” Under circumstances where petitioners *231never disputed the existence of a private right of action and the question had not been put to a test the decision in Burks offers a tempting invitation to bypass the issue. That course, in fact, was taken by the court in Chipser v. Kohlmeyer & Co., 600 F.2d 1061, 1067 & n. 14 (5th Cir. 1979) when faced with the precise issue in this case. In Chipser, however, plaintiff had filed his complaint prior to the amendment of the Act and the court determined that the implied right of action issue should be addressed in the first instance by the district court. For purposes of this appeal, however, we find the more expedient route is to apply the law in effect at the time of our decision and to reach the implied right of action issue.
. In Smith v. Groover, 468 F.Supp. 105 (N.D. Ill.1979), the court noted that Congress traced the inadequacies of the self-regulatory scheme to a number of factors:
First, the enforcement staffs of commodities exchanges were unable to handle the vastly increased trading volume. H.R. Rep.No. 975, 93d Cong., 2d Sess. 46 (1974). Also, exchanges faced “growing difficulties . as a result of private plaintiffs seeking damages against self-regulatory activities of the markets.” Id. at 48. Because an implied right of action could be brought against an exchange for failure to enforce its own rules, “attorneys to several boards of trade had been advising the boards to reduce — not expand exchange regulations designed to insure fair dealing.” Id. at 46. Finally, an exchange simply lacked the necessary motivation and vigilance to effectively police its own members.
Id. at 109-10.
. Commodity Futures Trading Commission Act of 1974, Pub.L.No. 93 463, 88 Stat. 1389 (codified at 7 U.S.C. § 1 eí seq.). The Act was further amended in 1978. Futures trading Act of 1978, Pub.L.No. 95-405, 92 Stat. 865 (codified at 7 U.S.C. § 1 et seq.).
. The CFTC may suspend or revoke the registration of a futures commission merchant or the designation of a contract market. 7 U.S.C. §§ 7b, 9. The CFTC is authorized to issue cease and desist orders against contract markets, 7 U.S.C. § 13a, and may assess civil penalties of up to $100,000 against futures commission merchants and contract markets. 7 U.S.C. §§ 9, 13a. Perhaps most significantly, the CFTC or the Attorney General at the CFTC’s request, may bring an action in federal district court against futures commission merchants and contract markets for a restraining order, an injunction or a writ of mandamus to compel compliance with the Act or its regulations devised by the CFTC. 7 U.S.C. § 13a-l. Further, the 1978 amendments to the CEA added a provision whereby a state may bring an action under the CEA on behalf of its citizens. 7 U.S.C. § 13a-2.
. In 1978, Congress further amended the CEA, P.L. 95-405 (Oct. 1, 1978), 7 U.S.C. § 1 et seq., to expressly allow the states, through Attorneys General or security regulations, to initiate actions in federal district court for CEA violations. This section does not indicate that Congress intended to extinguish private rights of action but rather, was meant to buttress the regulatory power of the CFTC, which is unable to regulate all aspects of commodities trading effectively. See also Jones v. B. C. Christopher & Co., 466 F.Supp. 213 (D.Kan.1979).
. In response to these developments the courts have either: (1) presumed the continuing validity of the private remedy without taking into account Cort v. Ash, 422 U.S. 66, 95 S.Ct. 2080, 45 L.Ed.2d 26 (1975), or the 1974 amendments. See Ames v. Merrill Lynch, Pierce, Fenner & Smith, 567 F.2d 1174, 1176 (2d Cir. 1977); Case & Co. v. Board of Trade of City of Chicago, 523 F.2d 355 (7th Cir. 1975); Kelley v. Carr, 442 F.Supp. 346 (W.D.Mich. 1977) rev’d on other grounds (6th Cir. 1980); E. F. Hutton & Co. v. Lewis, 410 F.Supp. 416 (E.D.Mich.1976); (2) determined that the 1974 amendments were intended to serve as a supplemental rather than a substitutionary remedy, and therefore permit plaintiffs to bring a direct cause of action in federal court without attempting to exhaust the administrative reparations remedy provided by Congress. See, e. g., Smith v. Groover, 468 F. Supp. 105 (N.D.Ill.1979); Jones v. B. C. Christopher & Co., 466 F.Supp. 213 (D.Kan. 1979); R. J. Hereley & Son Co. v. Stotler & Co., 466 F.Supp. 345 (N.D.Illf.1979); (3) held that while the 1974 amendments did not extinguish the implied right of action previously recognized, a plaintiff must first exhaust his administrative remedies. See Bartels v. International Commodities Corp., 435 F.Supp. 865 (D.Conn. 1977); Consolo v. Hornblower & Weeks-Hemphill, Noyes, Inc., 436 F.Supp. 447 (N.D.Ohio 1976), or; (4) determined that the combination of the 1974 amendments and the decision in Cort v. Ash, supra, extinguished the private cause of action since the CEA as amended did not meet the four-part test of Cort. See Berman v. Bache, Halsey, Stuart, Shields, Inc., 467 F.Supp. 311 (S.D.Ohio 1979); National Super Spuds, Inc. v. New York Mercantile Exchange, 470 F.Supp. 1256 (S.D.N.Y.1979); Fischer v. Rosenthal & Co., 481 F.Supp. 53 (N.D.Tex. 1979).
. See 120 Cong.Rec. Senate 30466 (1974) (remarks of Sen. Dole); 120 Cong.Rec. Senate 34998 -99 (1974) (remarks of Sen. Clark). See also Ames v. Merrill Lynch, Pierce, Fenner & Smith, Inc., 567 F.2d 1174, 1179 (2d Cir. 1977).
. Congress recognized that the “courts [had] implied a private remedy for individual litigants in the Commodity Exchange Act.” Remarks of Rep. Poage, 119 Cong.Rec. 41333 (1973). In fact, the Senate Committee on Agriculture and Forestry inserted a proviso into the exclusive jurisdiction section, 2(a)(1), that, “[n]othing in this section shall supersede or limit the jurisdiction conferred on courts of the United States or any State.” The proviso resulted from testimony warning that the cumulative effect of the reparation provision and the exclusive jurisdiction section might be interpreted as repealing the jurisdiction of the courts to hear private damage actions. Hearings on S. 2485, S. 2578, S. 2938 and H.R. 13113. Before the Senate Committee on Agriculture and Forestry, 93d Cong., 2d Sess., pt. 1 at 205, pt. 3 at 737 (1974). See also Smith v. Groover, 468 F.Supp. 105, 114 (N.D.Ill.1979).
Further, it is a rule of statutory construction that Congress is presumed to have been aware of existing constructions of statutes and does not intend to overrule them if the provision is re-enacted in substantially the same form. Alabama Ass’n. of Ins. Agents v. Board of Governors of the Federal Reserve System, 533 F.2d 224 (5th Cir. 1976); Hofmayer v. Dean Witter & Co., 459 F.Supp. 733 (N.D.Cal.1976).
. 7 U.S.C. § 2 states, in part:
That except as hereinabove provided, nothing contained in this section shall (i) supersede or limit the jurisdiction at any time conferred on the Securities and Exchange Commission or other regulatory authorities under the laws of the United States or of any State, or (ii) restrict the Securities and Exchange Commission and such other authorities from carrying out their duties and responsibilities in accordance with such laws. Nothing in this section shall supersede or limit the jurisdiction conferred on courts of the United States or any State.
. National Super Spuds, Inc. v. New York Mercantile Exchange, 470 F.Supp. 1256 (S.D.N.Y.1979), and Berman v. Bache, Halsey, Stuart, Shields, Inc., 467 F.Supp. 311, 322 (S.D.Ohio 1979), also held that the establishment of an extensive administrative reparations process and the plenary grant of disciplinary and regulatory power to the Commodity Futures Trading Commission evidenced a congressional intent to deny a private right of action under the Act, through application of the maxim “expressio unius est exclusio alterius”; the expression of one thing is the exclusion of another.
. The primary jurisdiction doctrine is a rule of judicial construction which permits a court, in exercise of its sound discretion, to defer to an administrative agency for the initial resolution of certain disputes. This doctrine is usually invoked when resolution of a dispute will require special skill or knowledge peculiar to a certain agency. See United States v. Western Pac. R. Co., 352 U.S. 59, 77 S.Ct. 161, 1 L.Ed.2d 126 (1956); Jones, supra, at 222; Hofmayer, supra, at 738; Shearson Hayden Stone, Inc. v. Lumber Merchants, Inc., 423 F.Supp. 559 (S.D. Fla.1976). The courts have generally refused to apply the doctrine to fraud claims under the Commodity Exchange Act. See, e. g., Smith v. Groover, 468 F.Supp. 105 (N.D.Ill.1979); Hofmayer v. Dean Witter & Co., 459 F.Supp. 733 (N.D.Cal.1978). But See Bartels v. International Commodities Corp., 435 F.Supp. 865 (D.Conn.1977); Consolo v. Hornblower & Weeks-Hemphill, Noyes, Inc., 436 F.Supp. 447 (N.D.Ohio 1976).
