(8)The DCMs operate under the supervision of the CFTC. The primary objective of the CFTC's compliance programme is to evaluate DCM compliance with applicable provisions of the CEA, including the 23 core principles with which DCMs must comply, and CFTC regulations implementing those core principles. To this end, the CFTC conducts examinations of a DCM's compliance with core principles and regulations relating to trade surveillance, market surveillance, audit trail, and DCM disciplinary programmes. Under the market surveillance programme, the CFTC monitors traders to ensure that they comply with provisions in the CEA and CFTC regulations. To this end, the surveillance programme monitors trading activity on DCMs, futures positions, swap transactions and swap positions in order to detect and prevent market abusive practices and to ensure compliance with the CEA and CFTC regulations. In addition, the market review programme reviews all DCM rule filings and the product review programme reviews DCM product terms and conditions filings; both programmes review the filings to ensure consistency with the CEA and the CFTC's regulations.
