Order Audit Trail System (OATS)

An order audit trail system (OATS) is a software application that records and tracks all orders executed on a trading platform. It is used to monitor trading activity and to comply with regulatory requirements.

OATS systems typically record the following information about each order:

* The time and date the order was placed
* The type of order (e.g., market order, limit order, stop order)
* The price of the order
* The quantity of the order
* The identity of the person who placed the order

OATS systems can also be used to track the execution of orders. This information can be used to identify potential trading violations, such as front-running or market manipulation.

OATS systems are an important tool for regulators and market participants. They help to ensure that trading is fair and transparent, and that market participants are held accountable for their actions.

Here are some additional details about OATS systems:

* OATS systems are typically used by broker-dealers, exchanges, and other financial institutions.
