A Trading Member or a Trading Representative must ensure that a daily record of orders received from customers is maintained. The record must show the identity of the Trading Representative, account identification of each customer, the specific order, date and the time the order was received, transmitted, amended, and executed or cancelled. For avoidance of doubt, the record may be kept in the order management system.

A Trading Member must have a robust system to prevent tampering of the audit trail of orders entered into the Trading System.
