Consolidated Audit Trail (CAT)

SEC Rule 613 requires FINRA and the national securities exchanges to jointly submit a National Market System (NMS) plan detailing how they would develop, implement and maintain a consolidated audit trail that collects and accurately identifies every order, cancellation, modification and trade execution for all exchange-listed equities and options across all U.S. markets. FINRA is working with the exchanges to develop an NMS plan that meets the requirements of Rule 613.

For more information, see the CAT NMS Plan website.


FINRA submitted its proposal in response to the Consolidated Audit Trail (CAT) RFP on March 21, 2014.

On November 16, 2015, FINRA was notified that it was selected as one of the final three bidders for the role of the CAT Processor.

FINRA looks forward to continuing to work with the self-regulatory organizations as they move toward completion of their CAT selection process.
