Normally, I don't make a habit of defending vendors. But we should all note that losses occurred on all accounts Demo and Live alike on Friday. It could be assumed that wins would also be shared among all accounts when they happen. Using the data provided here on myfxbook, it shows that this EA only has about a 50% win rate AND yesterday was a EU bank holiday. Even in back test reports provided by the vendor show periods of loss followed by large gains.
I'm going to let it run for another week. If the winning trend starts to falter, then I will stop using it also. But, based on all the factors I think it may (I repeat) MAY, be worth it.
