Spread backrest mt4

 
When doing backtest in mt4 I change the spread from 10 to 100 and it doesn’t make any difference on profit and loss of individual trade it only change the amount of trade taken. Why is that?
 
That's because you take the spread into account and adjust the SL and TP accodingly. If the lot size varies it's because of the way you handle your risk management when spreads are higher.
