I had a project I wanted to do that analyzes the books of public companies and finds the stocks with the best debt to equity ratio to find good ones to invest in. The problem is that data is hard to access, and sometimes you have to pay a company to get access to it. There is this Edgar system but it is mostly XML files and I don't know how to navigate it to find the right one. I'd need an API that lets me pick each stock and return the values I want to store in a database so I can do analysis on them to find the best debt to equity ratios. When a company has a lot of debt it is usually a sign that it will struggle in the future. But yeah Robo-Advisers are very popular right now, and banks should be scared as it takes away chunks of their business. There used to be Excel spreadsheets that did Candle Stick charts and other stuff to find stocks to pick. Stuff like that got automated into AI routines.
