I recognize the GUI, that is from MBtrading. ECNMarket has the same funding requirements and the same fee structure as MBtrading. MBtrading has an IB program I found out from another trader. My goal is to get EA converted over and run against ECN like this one. I just need to know the FIX Protocol version used. I have a few emails out now, and some ECN list their protocol versions. (4.2 seems common).
