There should be a law against firms using the phrase "smart" router. It has become so cliche. Everyone touts having smart order routing but many are just... 1) piggybacking someone else's smart software E.g. alll orders go to an ECN that re-routes 2) going through a step by step process E.g. 1. routes to SNET or SuperSoes, 2. if unfilled, sends to ISLD where it never moves again. I hear it is too hard for programmers to have the market analayzed prior to order routing, becuase it takes too long. So most firms cheat. Where did all the good firms go...??
