I'm working on a project on which user-submitted content can be invested in, with real money, by other users, obviously with the hope that there will be a ROI via royalties. But I have only a basic understanding of how the stock market and trading exchanges work. I'm wondering what books/resources I can read in order to have a thorough enough understanding to be able to create a custom one. I'm a mid-level software developer so I'm confident about my ability to be able to build this system once I know the scope. Thanks in advance
