I'd like to share my thought with you on some strange incident during backtesting. I noticed that when you backtest exactly the SAME Expert Advisor with THE SAME parameters, you can get completely different results between two MT4 platforms for two different brokers.
Well, I can understand that brokers quote differently, but hey. It should not create that huge disproportions as you can see on below screens.
Below is the comparison of account balance - it's exactly the same EA (same code, same parameters, same currency, same period) backtested on two different brokers. The accounts vary on account balance and leverage, but as far as I know this should not have such impact.
Have you ever had similar experience to this?
data feed is different hence the difference
opening time of monday candle can be different also
