MetaTrader 5 and % based commission issue

I just tested the commissions on MT5 netted engine and it works fine.

Can you record a video for me to see the problem?

Also your project config and retested SQX strategy would be helpful.

When I replicate such strategy in backtrader engine all profit is eaten by commissions.

For 200-400 trades strategies, profit is real.

I tried to improve the attached strategy using your config and the results seem fine to me.

It makes sense to me that the commissions eat up a big portion of profits when there is a large amount of trades.

Can you attach some of the problematic strategies?

Just looked at this issue with more experience.

In the beginning I tried replicating MetaTrader5 in Backtrader.

Engines are very different and replication leads to very different results.

So this bug might be invalid.

I am closing this task. If you experience any other problems, let me know.

Best regards,

Tomas
