How can I completely remove or disable an Expert Advisor?

 

I already turned off Algo Trading and ensured the EA is disabled on every timeframe, but it continued opening trades and significantly affected my deposit.

Could you explain the correct way to fully stop or uninstall an EA so it cannot place any further trades?

 

You've probably migrated your EA to your MQL5 VPS and that is why it keeps opening trades.

You need to migrate an empty chart to your MQL5 VPS in order to remove your previous setup.
