Is there any way to mofidy the broker spread in backtesting?

 

My broker that uses MT4 widen the spreads after market (Ask-Bid) of my local currency . I mean, after the interbank market closes, the broker continues placing quotes in the plataform but with a bigger spread. (duplicate it).

So If I try to backtest any EA after market in MT4, the test will include all trades with this unreal "after market" spread.

Given this broker feature, I must test all my EA during the trading session to get backtesting figures with the real market spread.

Is there any way to change or fix the spread in my backtestings after market ? (Using MQL code perhaps)

Best regards

Hernan
