Education only. This calculator shows arithmetic from the numbers you enter. It is not advice and not a recommendation to trade any contract or any size. Firms define drawdown, lock levels, daily limits, contract caps and copy-trading rules differently, and your firm's current rulebook decides. Tick values are standard CME Group contract specifications; verify them on your platform. Futures trading involves substantial risk of loss. Prop firm evaluations are paid tests that most people do not pass.
