Regulation Automated Trading

On December 17, 2015, the Commodity Futures Trading Commission (``CFTC'' or ``Commission'') published in the Federal Register a notice of proposed rulemaking (``NPRM'') proposing a series of risk controls, transparency measures, and other safeguards to enhance the safety and soundness of automated trading on all designated contract markets (``DCMs'') (collectively, ``Regulation Automated Trading'' or ``Regulation AT''). Through this supplemental notice of proposed rulemaking for Regulation AT (``Supplemental NPRM''), the Commission is proposing to modify certain rules set forth in the NPRM. Any new or amended rules proposed in this Supplemental NPRM reflect only those areas where the Commission believes that additional notice and comment may be appropriate before enacting final rules. Procedurally, this Supplemental NPRM is not a replacement or withdrawal of rules proposed in the NPRM. Unless specifically amended herein, all regulatory text proposed in the NPRM remains under active consideration for adoption as final rules. The Commission welcomes public comment on all aspects of the Supplemental NPRM.
