How do I get my Codex better building math related projects. Specifically Finance/Trading related stuff.

As the 15 year old founder of Atom design with my brother, JJ, I've led my friends and I to learn more about the AI coding world. However, I'm not really content with a web design business (it might not be up right now because of the PHP hack.) I wanted to make passive income which is why I started a personal project to build a Trading algorithm that could do that. If you have any tips from that field I'd be grateful!
