And to answer all your questions: It is stable, but you should be careful with the options you use to run the container: if you use --rm , every time you exit the container, the state will be reverted to its origin, so if we assume that Zorro stores the state of current opened orders in files, these files will be deleted, and next time you start the container, Zorro will not know anything about them.

Stability is as good as your Linux server. I don't recommend mixing development environments with real trading environments though.

I have also tried the oanda api in this Docker container and works fine.

I am really happy I've succeded in "dockerizing" Zorro+MT4, it runs incredibly well and it does not consume too much resources.
