I backtested an EA on two different brokers, with everything the same, and they gave different results

[Julio Cesar Vieira Alves Junior]

I had never paid attention to this before, but recently I backtested an EA on two different brokers, with everything the same, and they gave different results, it wasn't an extreme change, but now I don't know which one I should trust more.

Different trading conditions, spread and other factors can give different results between brokers, this is not a surprise.

For example an ECN commission based broker would give better results in a scalping strategy, than a standard broker with a large spread.

Consider your results and available options and decide.

Discussion or recommendations about broker are not allowed in this forum.

It must not be same - because two different brokers and two different data/quotes and so on.
read summary post #20 for details (and read this short thread too - Backtesting results in different results on different brokers ).

By the way, the backtesting results may be different in case of one broker - the thread about it:
Same broker, different results
