As part of a countervailing member trading agreement (CMTA), several brokers also enter into an agreement for only one of them to trade for a single client, whether or not the client enters derivatives transactions with all brokers. With this agreement, an individual investor may have commercial relationships with many brokers at once, but all the trades of different brokers are settled by a single brokerage company. 8. The OCC does not propose the inclusion of an action identifier for marketmakers, as the OCC understands that these trades already contain information allowing a countervailing member to assign trades to individual market makers accounts. See notifications, 84 EN to 13076, 6. Often, investors or traders ask questions about the importance of a counterparty trade agreement (CMTA), the significant benefits of the agreement are listed below; www.interactivebrokers.com/en/…/clearing_member_trade_agreement.htm Section 17A(b) (3) (F) of the Securities Act provides that the rules of a clearing house are intended, among other things, to promote (i) the prompt and precise settlement and settlement of securities transactions and (ii) to promote cooperation and coordination with those involved in the settlement and settlement of securities transactions, and (iii) in general, in order to protect investors and the public interest.  On the basis of its review of the protocol, the Commission considers that the proposed regulatory changes with regard to the action identifier are intended to promote the rapid and precise settlement and settlement of securities transactions and to promote cooperation and coordination with those involved in the settlement and settlement of securities transactions for the reasons outlined below. For options transactions, CMTA must conduct transactions through the Options Clearing Company (OCC). The OCC supports the clearing process for different types of options traded on many exchanges. The Securities and Exchange Commission (SEC) regulates the OCC.
A CMTA is an agreement between different brokers to allow and settle the trades of all brokers involved through a single broker. As an investor can have relationships with several brokers, they can launch trades with several of them at the same time. But when it comes time to remove these trades, they can stand out with only one broker. Without the countervailing member trading agreement, the investor would make transactions with different brokers and the trades would be clear to several brokers. This can be complicated and time-consuming when it comes to closing positions. With a CMTA on site, one of the brokers will present all trades to the clearing house for settlement. 10 www.nasdaq.com/investing/glossary/c/clearing-member-trade-agreement. However, the CCO does not propose to make the inclusion of an identifier capable of acting a precondition for the acceptance of exchanges. First, the CCO`s member transfer process (“CMTA”) allows a compensator member who completes a securities options contract (i.e. the performance countervailing member) to send the trade directly through oCC to another countervailing member for customs clearance and settlement (i.e., the carrying trimer member).  As part of the CMTA process, a countervailing-exporting member may send options transactions directly to the omnibus accounts of a pallor member with OCC for settlement and settlement, without providing information on the specific accounts to which trading should be allocated. Second, a broker may, as part of the “give-up” process, make a transaction on a stock market and assign that transaction to the omnibus account of a countervailing member.
In particular, a broker who is not a countervailing member of the OCC may trade a client in client transactions and then “abandon” trading with the client`s countervailing broker who must be a countervailing member of the CCO, without identifying the client for whom the transaction was made.
