I'm not sure what you're planning to discover by that. What makes modern finance (particularly stocks) so hard to manage is that it's very emotional. People invest based on what they believe in, and when they get scared they sell. Is the goal to anticipate this and see if the AI can replicate it exactly, or are you expecting it to do it better somehow? If it's the latter, it would be very hard to measure success, because you can't measure how the market would react without involving the market.
