The Consolidated Audit Trail

The Consolidated Audit Trail will track orders throughout their life cycle and identify the broker-dealers handling them, thus allowing regulators to more efficiently track activity in Eligible Securities throughout the U.S. markets.

The primary goal of Securities and Exchange Commission (SEC) Rule 613 is to improve the ability of the SEC and the Self-Regulatory Organizations (SROs) to oversee trading in the US securities markets.
