• The Order Audit Trail System (OATS) is a computerized regulatory mechanism that maintains detailed records of securities transactions.

  • OATS requires FINRA member firms to automatically register and report orders to FINRA.
  • OATS was created to facilitate the tracking and verification of orders if necessary; for example, in the event of a trading error or suspected market manipulation.
  • Individual traders and investors are not required to provide OATS data to FINRA. This is the job of a broker or member firm that processes client orders.
