You know a feature I think might be nice since all the exchanges work in tandem basically. Yesterday my BTC-e went to a buy signal but Bitstamp never did. And then BTC-E went back to sell today..So basically it was a loser trade. I would like a feature that my bot doesn't make a buy or sell without the other exchanges I'm trading on having the same signal. Does that make sense or do you think it could be helpful or not?
I certainly know where you are going with that, but unfortunately it is not that simple. While the exchanges normally take cues from GOX (for now), exactly when and to what extent is dynamic. Go back in the chart data and see how that would have worked out for you, and I think you will find a lot of loss.
A better solution is to be able to test/tune for each exchange, not have to blindly use settings tuned for GOX on all three.
