Idea is good and something I would like to make myself some time but right now this has too many issues (even download version). Setting up a trade route is not very intuitive. And once I did that it quickly sold all supplies I didn't see any easy way to stop it. Seeing more than 2 decimal numbers on proces also cluters UI.
Since it is made in Unity maybe you could add me to your team? I could help you improve a few things if you want.
