stock ahead


A security trade execution order situation in which two orders are received at the same time, and the order of execution is then determined by the rules of the particular exchange. The NYSE, for instance, stipulates that when two orders are received simultaneously that the order with the larger volume is to be executed first. The broker placing the smaller trade is informed that it was not executed because there was another "stock ahead".
