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.
