Be extremely careful with your server's security. I would never want to be responsible for someone else's exchange access keys. It's a honeypot if there ever was one. (Even with limited access rights) Focus on the "local Open Source client" even though that will probably be much harder to monetize. Anyway, building trading bots is a lot of fun and there are plenty of strategies that can make a decent return.

The security aspect is something I'm concerned about for sure. I have even considered making the Open Source client mandatory, but that could be overkill.
