1. APAs and CTPs shall set up and maintain appropriate arrangements to ensure that they accurately publish the trade reports received from investment firms and, in the case of CTPs, from trading venues and APAs, without themselves introducing any errors or omitting information and shall correct information where they have themselves caused the error or omission.

2. APAs and CTPs shall continuously monitor in real-time the performance of their IT systems ensuring that the trade reports they have received have been successfully published.

3. APAs and CTPs shall perform periodic reconciliations between the trade reports they receive and the trade reports that they publish, verifying the correct publication of the information.

4. An APA shall confirm the receipt of a trade report to the reporting investment firm, including the transaction identification code assigned by the APA. An APA shall refer to the transaction identification code in any subsequent communication with the reporting firm in relation to a specific trade report.
