Order Audit Trail System (OATS)
OATS Retirement
On June 17, 2021, FINRA filed its proposed rule change for immediate effectiveness to retire OATS based on its determination that the accuracy and reliability of the CAT meets the standards previously approved by the Commission. As a result of this filing, the OATS Rules will be deleted from the FINRA rulebook effective September 1, 2021.
August 31, 2021 will be the last “OATS Business Day,” as defined under Rule 7450(b)(3), for which OATS will accept order events and perform routine processing, including incorporation of corrections and repairs of rejections. Firms must continue to report to OATS all order events that occur on or prior to August 31, 2021. Reports submitted to OATS for order events that occur after August 31, 2021 will be rejected.
OATS will continue to accept reports for order events that occur on or prior to August 31, 2021, (including, but not limited to, late and corrected reports for such order events) through September 16, 2021. Firms must continue to ensure their OATS reporting is accurate and complete for all order events occurring on or prior to August 31, 2021. To assist firms in meeting their reporting obligations, existing OATS guidance will remain posted and available on FINRA’s website for a period of time following OATS retirement.
If you have any questions, please contact the OATS Help Desk at (800) 321-6273 or via email.
FINRA has established the Order Audit Trail System (OATS), as an integrated audit trail of order, quote, and trade information for all NMS stocks and OTC equity securities. FINRA uses this audit trail system to recreate events in the life cycle of orders and more completely monitor the trading practices of member firms. Under FINRA Rules 7410 - 7470, FINRA member firms are required to develop a means for electronically capturing and reporting to OATS specific data elements related to the handling or execution of orders, including recording all times of these events in hours, minutes, and seconds, and to synchronize their business clocks. These Rules were approved by the SEC on March 6, 1998.
