AutoTrading turns OFF immediately after enabling (Not EA / Not broker issue)

 

I am experiencing a critical issue where AutoTrading turns OFF immediately after enabling it.


Environment:

- MetaTrader 5 on Windows 10

- Also reproduced on Mac (Wine environment)

- Broker: XM (TradeFin Limited)


Issue:

- When I click "Algo Trading", it turns ON briefly and then immediately turns OFF

- The option "Allow Algo Trading" in settings also gets unchecked automatically


What I have confirmed:

- Happens even with default EA (ExpertMACD)

- EA compiled with no errors

- Manual trading works normally

- Using master password (not investor password)

- Broker confirmed that EA trading is allowed

- No VPS, no Python API, no external integrations

- Occurs on multiple machines


Logs:

Only shows:

"automated trading is enabled"

"automated trading is disabled"


No server-side restriction messages.


Conclusion:

This does not seem related to EA or broker.

It appears that MT5 client forcibly disables AutoTrading.


Has anyone experienced this issue or knows what could cause MT5 to disable AutoTrading automatically?
