It should not affect your results in the tester… maybe because there is difference between your broker and metaquotes 
 
One reason why back testing doesn't work is because market conditions constantly change. Factors that have affected the market in the past may have no relevance in present day activity. Furthermore, new conditions such as volume, interest rate, and volatility may create new inputs for a market's behavior.
