I'm satisfied with StrategyDesk... I can make it do just about everything I want it to.
Plus I'm just not that sold on automated trading in general, so seeking another platform just because I don't like the way the live strategy engine works is not worth it.
it the Ticks are too noisy for your formula, then you can always AND your formula with an indicator that has some type of smoothing mechanism as a double-check. That works well for me.
