Article 28 Client order handling rules

1.  Member States shall require that investment firms authorised to execute orders on behalf of clients implement procedures and arrangements which provide for the prompt, fair and expeditious execution of client orders, relative to other client orders or the trading interests of the investment firm.

Those procedures or arrangements shall allow for the execution of otherwise comparable client orders in accordance with the time of their reception by the investment firm.

2.  Member States shall require that, in the case of a client limit order in respect of shares admitted to trading on a regulated market or traded on a trading venue which are not immediately executed under prevailing market conditions, investment firms are, unless the client expressly instructs otherwise, to take measures to facilitate the earliest possible execution of that order by making public immediately that client limit order in a manner which is easily accessible to other market participants. Member States may decide that investment firms comply with that obligation by transmitting the client limit order to a trading venue. Member States shall provide that the competent authorities may waive the obligation to make public a limit order that is large in scale compared with normal market size as determined under Article 4 of Regulation (EU) No 600/2014.
