something important from me here:
Min count of trades:50 is too small number. Specially in Forex you should go with min 300-400 count of trades.
Basically when the generator/reactor works it looks for combinations between different entry and exit conditions, indicators with different parameters etc., so when you have strategy with only 50 count of trades this might be not a stable strategy. We want to see bigger count of trades so we know that this combination of indicators, parameters, SL, TP and so on, works on more trades(longer period of time).
