It might just be me being a new customer of theirs, still getting a feel for the whole thing (I'm using QuoteTracker API to connect), maybe that has something to do with my fills but anyway.... I keep placing limit orders through QT and they keep getting filled 1 or 2 cents higher than the limit, using SMART order routing. Anyway to avoid this? I.E. Today: Buy WMT Limit 50.41 Smart But IB filled me at 50.43, it's kind of annoying when you know your in a stock then you check and figure out you got filled at something else, screws me up and my calculations. Anyone have these problems or know how to potentially fix it?
