70% Win EA but with huge amount of charts errors. How to fix it ?

New comment
 

Hello everyone. I'm new here :)

I tested every solution that i found online but nothing worked and the errors are still persisting. I contacted the seller and he assured me that the EA's performance won't be affected by this but I'm still worried about this and need a professional opinion.

902 Mismatched charts errors is creeping me out! How do I fix this ?

Here is the overall performance of the EA.

EURUSD Backtest


Edit: I use Alpari broker.

There's no way to fix the mismatched errors. Backtests are only an approximation. If the EA will perform like this in the real market or not depend on several factors. 

If any of these is true, the EA won't make money and will lose it instead. Or make little money and then big loss.
1. If the EA is a night scalper.
2. If the EA has breakout strategy.
3. If the E is a news trader.

This is a super great EA you have there ! Performing so with a spread @ 30 ain't easy ! 

Anyway, you could redownload data (I see you're using MT4) from another source.

Thank you for your response.

Why can't they be fixed ? I understand that these mismatched errors won't affect the performance of the EA in the future ?

The EA doesn't use any of the factors you mentioned as far as I know. It also doesn't make a big loss because it has a stop loss based on account percentage  (1% in the backtest).

Yeah it's great in the backtest. I did redownload the data from the History center in MT4 (alpari broker) but it always makes the same amount of errors 902 mismatched errors which is frustrating because I don't know why and can't risk putting it on real account.

Try tickstory or tick data suite or any of those third party data manager. 

 
You should send your ea mq4 file here if you need help other way no one can help you without observing your source code.

He's kidding you, just use fresh datas - you won't need to share your code

Thanks. That is exactly what I'll do :)

lol yeah I guess so. Thanks :D


I don't have the code to share. I have only the ex4 file!

 
Note: I didn't say that if the EA doesn't use those factors it will perform as in backtest, just that if it had them, it won't. 

If it doesn't have them, often the backtest with low quality is good enough. In that case I would attach it to demo account and let it trade for 1 month, then backtest and compare results only of that month. If you're ok with the comparison then I would attach to live account.
