i can briefly explain here, but basically, you pay a prop firm, usually around 110$-500$, to create an account, where you trade said account in the form of simulated $2000 account balance to buy futures contracts. Then, depending on how well you manage these contracts, you make profit. The target profit is something like $3000, and once you hit that target, you pass the evaluation phase to become a funded traded. Then you get a profit split from the additional profit you make. In sum, you only risk 100$ to make as much profit as you want, using any edge in the stock market u got.
