Why did this happen?
This error happens because more than one script/Expert Advisor is trying to perform operations on your account.
How to solve this error?
- Restart the terminal.
- Install multiple MT4 terminals for the same account and set up fewer charts for each. When fewer EAs exist, their chance of operating simultaneously will be reduced. When installing multiple terminals, please remember to change the file name to enable download.
Download MT4 and MT5 from the Exness website.
