The U.S. Securities and Exchange Commission announced that it has extended three of the compliance dates for Regulation NMS.

The commission is extending the three compliance dates for rule 610 and Rule 611 of Regulation NMS to give automated trading centers additional time to complete the rollout of their new or modified trading systems.

The SEC has extended the Trading Phase Date until March 5, (previously Feb. 5), the Pilot Stocks Phase Date until July 9 (previously May 21), and the All Stocks Phase Date until Aug. 20 (previously July 9). The Completion Date of Oct. 8, remains unchanged.

Automated trading centers must operate trading systems that comply with the automated response and other requirements of Regulation NMS, the SEC notes. The trading systems can be operated by a self-regulatory organization or operated by a broker-dealer that displays its quotes on the NASD’s Alternative Display Facility.
