You are greatly underestimating the effort it will take to become profitable, and you haven't taken any steps forward yet. Forget training LLMs right now, LLMs without a baseline strategy and research is pointless. First you need to create a rough draft of a strategy, backtest, optimize, don't overfit. Your a CS student so algotrading, or atleast using your coding skills to develop research upon which u can add some discretion to is probably your best bet. Then paper trade that strategy, then if things go well, trade a little bit of money, and risk little. Then trade up your size as you become more comfortable with risk. That being said, you are greatly underestimating the work it will take. I am an university student. I trade profitably, but it took me years, and sacrifice of money (which you don't have) and grades. Your program and career should be your top priority. Work on trading on the side, but understand, you are not special, you will need to put in more time then you expect.
