Machine

• macOS Catalina, 10.15.3
• crypto-signal branch
• Docker version 4.1.1

Additional context Only modifications have been done to the config.yml folder, I copied it directly into the "app" folder. Within Dockers image itself, logs states "python: can't open file 'app.py': [Errno 2] No such file or directory".

Used xcode to edit properly, seems to have done the trick. Problem was on the indicators section, used the example provided and edited accordingly into the code. Works well!
