Great Automated Trading App

There are a variety of resources that allow nontechnical individuals to build playbooks such as AI assistant. If building is not your thing, you can always use others’ playbook if they are public. I would recommend understanding the playbooks however prior to investing and not just looking at backtests.

MacOS support

Love the app, and it was fantastic when it had macOS support. It would be wonderful to see it return, along with macOS widgets support in the future. The app is great, but having these features would make it perfect!
