Effective June 12, 2017, The Nasdaq Stock Market (“Nasdaq”) will be introducing two new optional port/MPID settings for Post Only orders, allowing Post Only orders to be cancelled if the order, upon entry, would be price slid due to locking or crossing a protected quote of another market center or a resting displayed order on the Nasdaq book.

Nasdaq has added two new cancel order reasons for Post Only orders that are cancelled due to these new settings:

Reason Explanation
F Post Only Cancel. This Post Only order was cancelled because it would have been price slid for NMS.
