Quote from asa:
The CME offers traders who create a firm solely devoted to trading the ability to apply for an Electronic Corporate Membership (ECM). How do you know if your firm qualifies? All profits and losses are produced and taxed at the firm level, all funds and trading activity come from and benefit only the firm. The ECM is a class of Chicago Mercantile Exchange membership that allows proprietary trading firms the ability to benefit from reduced clearing fees.
There are two kinds of ECMs available, those that hold membership (ECM-H) and those that simply meet the volume requirements (ECM-W). ECM-Hs are not subject to any minimum trading volume, but ECM-Ws are. ECM-Ws must average 25 round turns per day to be eligible for the membership waiver. If the firm does not meet the minimum trades, there is a period of two weeks to obtain membership, and if it does not do so the membership will expire. To get the membership again, you must reapply. ECMs do not have to pay NFA fees.
there is a one time non-refundable $1750 application fee
