The Securities and Exchange Commission adopted Rule 11Ac1-5 (now known as Rule 605 of Regulation NMS) to improve public disclosure of order execution practices. Under Rule 605, market centers that trade national market system securities are required to make available to the public monthly electronic reports that include uniform statistical measures of execution quality.
