What VPS do you use and what kind of ping do you get from icmarkets from where you are?
I am trying the ea at the moment but my results were not the same as yours but still profitable so far.
I am running 3 instances of mt4 on it, which I may have to re-think. I set the scalper to the highest cpu priority, but may need a dedicated vps. I will test with the other EA's turned off at that time to confirm.
