CPTrader,
I just purchased OQ last week and I'm in the process of moving over my ATS from TradeStation. I'd be interested in comparing notes with you. I'll get back with you in a few weeks after I'm up the curve a little further.
I'm leaning toward OpenTick for data since I need access to historical tick data. I'd appreciate any comments on your experience with data providers for OQ thus far.
