I am currently using NinjaTrader to send my trading signals from TradeStation to IB. This implementation works flawlessly so far. However I need to increase the amount of charts I trade on and as you all know there is a limit in Windows 32 bit systems. Unfortunatelly NinjaTrader DLL does not work on Vista 64bit. I open this issue with them almost a year and they promissed to fix it in relase 7.0. I am still waiting for that release now. I would like to know if somebody here is using the TS->IB setup in Vista 64bit with a programmable interface like: 1) HyperOrder 2) TWSLink Since my system needs close control I can't use the Email interface products like TradeBullet. I apprecitate anybody that share their experiences. Moscu.
