In November 2016, the Securities and Exchange Commission approved a national market system (NMS) plan that required national securities exchanges and national securities associations ("SROs") to create a single, comprehensive database known as the Consolidated Audit Trail (CAT) that it stated will enable regulators to more efficiently and thoroughly track all trading activity in U.S. equity and options markets. FINRA has been selected as the processor for CAT.
An IBKR client falls under the rule and is obligated to report to CAT if they are a member of a U.S. national securities exchange or a U.S. national securities association that handles orders or quotes in NMS equity securities, OTC equity securities or listed options. Unlike the current OATS reporting obligation, the CAT reporting obligations extend the scope of covered instruments to options too.
IBKR will offer CAT reporting services for its clients that are obligated to CAT report. To configure this, please refer to the steps outlined below.
