I've been using ThinkOrSwim as my sole broker for trading everything. This question is similar to the one about trading forex on IB. Could those of you who use TOS to trade futures and forex , especially lower time frames such as 15min, 5min or 1min have some suggestions or comments of what they think about trading this way on TOS? Is it worth it in the long run to daytrade and scalp on TOS? Or would you recommend not using TOS at all for this? Has the speed improved do you think since when TS Ameritrade took over? How about Prodigio? How does ThinkOrSwim compare to IB coupled with Ninjatrader? Thanks.
