If I remember right, the EA gets reloaded on symbol change. This will reset your global variable _sym.
You will need to use global terminal variables for persistent storage across reloads.

Nothing is changing while your code is running. You will break out of the while because of IsStopped and go through a deinit/chart change/init cycle.
- Indicators are reloaded, EAs are not.
