For those traders with automated system experience, what Platform would you suggest to use in conjunction with Interactive Brokers: a) For speculatively long and short trading of just one Index futures symbol. eg SPY. b) The trading system method has already been determined, ie doesn't require testing. c) Charts, Back testing and Indicators not required. d) Web based preferably so it can be monitored remotely. e) Speed or latency not important as this is not HFT. and the last one might be asking a bit much but thought to ask anyhow... f) The ability to trade the same instrument if possible but at different time periods, eg simultaneously, 5, 10, 15, 60 minute bars and perhaps EOD bars.
