I recommend not to use CHFJPY, USDJPY, AUDUSD, AUDCAD. risky couples. but it's up to you.

As shown in the attached... modify request for AUDUSD 0.63018 at 22.11.04 00:29:28, failed with error(Invalid Request).

So, it eventually entered 0.62868 and there was a loss.

I wonder if anyone has lost money with this kind of message.

I want to know how to solve it..

You've set everything up correctly. Today was a losing night, unfortunately. I suffered just like you. Do not be upset, there have been such days before and the adviser was easily restored. Let's recover this time.

It's not a new problem.

Actually, I already uploaded comment here for other user's advice. ( comment num #142)

"Invalid request"... This problem happens over and over again.

If that message can be solved, all of my other problem will be solved.

Hello, is it possible to add option for trade direction for MT5? , e.g. I only want to trade Long.

Thanks

ignore -- Found it 

This error is still in default settings...

Hello,

1. The multisymbol backtest is horrific anyway - but it gets way worse when the "security settings" are used. Why is that? Those shouldn't have an impact at all (maybe "close on loss of balance" could have a tiny impact, but even the others have).
2. Which of the three security settings takes only into account what is done by that exact magic number, and which uses the overall account values?
   

Thanks for the fast answer!

I will try with better quality data then. But I noticed that the security settings also slow my backtest down significantly when in single mode. For six years of backtest in single mode, it takes more than two hours instead of a few minutes. Something seems very much off there.

Thanks for the hint, but I just want to set it as a safety net. I use conservative settings (0.01 lot per 800 USD), so the security settings (something like 10% or 20%) should never apply.

send me a private message with the set you are using. I will check what is the drop in speed
