Getting Started

The Audit Trail test suite provides an interface for customers to verify that they can successfully upload a comma separated value (CSV) file, containing audit trail data from CME Group.

CME, CBOT, NYMEX and COMEX Rule 536.B.2. (“Globex Order Entry – Electronic Audit Trail Requirements for Electronic Order Routing/Front-End Systems”) requires that the electronic audit trail associated with any system that accesses the CME Globex platform through the CME iLink® gateway contain a complete and accurate record of all activity through that connection, and account for every electronic communication by the order routing or front-end system from the time such order routing or front-end system receives or generates an electronic communication until it is communicated to CME Globex. Further, the Rule requires that CMFs guaranteeing a connection to CME Globex are connecting for maintaining, or causing to be maintained, the electronic audit trail for a minimum of 5 years.

Firms connecting for the order routing / front-end audit trail of a trading system that accesses CME Globex through the CME iLink® gateway must have the ability to display data in the required format. Exchange Drop Copy messages or files do not meet the requirements of Rule 536.B.2., as Drop Copy only reflects an Exchange-level audit trail and will not include information internal to the firm’s system. Further, the connected entity must ensure that all trading functionality supported by the system is appropriately reflected in the audit trail.

For the convenience of those connecting for such order routing or front-end systems, the Exchanges have updated the Client Systems Wiki with the new data definitions, required format, and validation rules applied through the certification process of the minimum acceptable audit trail elements that such systems must capture.

The files must be in CSV format. The CSV files must also be continuous; the files must contain all audit trail data on one tab of the spreadsheet. If the data is not continuous, the test will fail and all previous tests will need to be retested.
