I am currently working with NinjaTrader, but I find that it has no real good story when trying to work with tick data. NinjaTrader, like most platforms, is concerned more with chart based systems, where the end of each bar the system is executed. I am looking to backtest and trade off of tick data. I have looked at OpenQuant and RightEdge, but not found them to be very easy to work with. Has anyone else done any high frequency tick analysis and if so what software are you using?
