(19)Iceberg orders are orders which have a displayed volume (peak) available for execution relating to a portion of a quantity and a hidden volume relating to the remainder of the quantity, kept in the order management facility which is capable of execution only after execution of the disclosed order. To cater for the possibility of execution of the hidden part of iceberg orders in narrowly defined circumstances, Article 8 of Delegated Regulation (EU) 2017/587 on the order management facility waiver should be amended.
