Quote from jimrockford:
I apologize, IBSoft. This resulted from a gap in my knowledge. I was trying to answer what I thought was the question, as to why one would not use a plain vanilla SMART order when one wants to participate in the opening print, and would instead direct route the order to the exchange. The misuse of a plain vanilla SMART order, when one wants to participate in the opening print, is a common mistake. I was not aware of the newer improvement you mentioned, allowing SMART orders to be flagged for re-direction to the exchange, just prior to the open, for participation in the opening print. If I had known about the improvement, my answer would have been more complete and not misleading. Sounds like a good new feature. Sorry!
