I've been with IB for years, but over the past few months their stock SMART order routing fails to execute my orders on occasion. I send out the order, always three cents ABOVE the offer, if I am buying, it goes out on Island(why I do not know), and does not route to the exchange that has the best offer, sometimes it gets filled sometimes not. It mostly happens on the SKF,TLT,IAI etc. I seems you are no longer able to eliminate a specific exchange from SMART routing. Since these stocks move so fast its impossible to direct route. Anyone has this trouble? Any solutions?
