The robot performance depends on robot settings and also on broker properties certainly. WallStreetForex robot is not an exception. So i choosed ECN broker with lowest spreads possible.
My Wall Street Forex Robot are following:

DEFAULT settings, except:


Magic: i replaced by another random 7digits number
EA_Comment: I added trade commnet "WSF3.9"
FixedLots: I decreased lot size from 0.1 to 0.05 because i started with 500USD account.

That are all changes i made. Later i may think about enabling AutoMM value, but not now when starting.
