(13)It follows from Article 27(1) of Directive 2014/65/EU that the order execution policy should also enable investment firms to obtain the best possible result for their clients when executing client orders while dealing on own account, including when engaging in matched principal trading (back-to-back trading) or dealing against the investment firm’s proprietary capital. The order execution policy of an investment firm should therefore specify how it aims to obtain the best possible result for its clients when executing client orders by dealing on own account and explain the procedures in place to assess and avoid detrimental risks for clients in those cases. For the same reason, the order execution policy of an investment firm should (i) contain measures that are appropriate to identify, manage and prevent conflicts of interest between the investment firm and its clients, as required by Article 23 of Directive 2014/65/EU and Articles 33 and 34 of Delegated Regulation (EU) 2017/565, (ii) explain the procedures in place to ensure a prompt, fair and expeditious execution of client orders where the client limit orders cannot not be immediately executed under prevailing market conditions, and (iii) specify, when clients’ orders are executed over-the-counter, how the firm ensures the fairness of the price in compliance with applicable Union law.
