On or around January 13th 2025, The Nasdaq Stock Market (Nasdaq), Nasdaq BX, and Nasdaq PSX will stop supporting the ability to add a MaxFloor (Reserves) value when replacing a non-displayed order via the INET FIX protocol.
Currently, when replacing a non-displayed order without reserves via INET FIX, customers can specify a MaxFloor value on the Order Replace message. This order behavior will no longer be permitted and requests to add reserves to the replacement of non-displayed order will be rejected. Customers should instead be cancelling the non-display order and sending a new reserve order.
For any questions, please contact Nasdaq Trading Services at +1 212 231 5180.
