On July 8, FINRA released a targeted examination letter it sent to 10 firms to assess their compliance with requirements related to order routing and execution quality of customer orders in exchange listed stocks during the period of January 1, 2014 to present. The letters include numerous requests for information, including requests that each firm explain: (i) how it uses reasonable diligence to ascertain the best market for orders that the firm routes for execution to an exchange, or broker-dealer, so that the resultant price is as favorable as possible for its customer under prevailing market conditions; (ii) how the firm’s exchange order-routing decisions are made for customer non-marketable, customer market, and marketable limit orders; and (iii) how the firm reviews the execution quality of such orders. The letters also include requests related to each firm’s use of the “Smart Order Router.”
