How prop firm risk works
Passing a futures evaluation is less about big wins and more about not breaking three numbers: the trailing drawdown, the daily loss limit, and the consistency rule. Pick your firm above and the calculator loads its current rules, then sizes your trade and shows the contract cap and pass plan.
Trailing drawdown
The trailing drawdown is the most you can fall from your account's peak before it fails. End-of-day (EOD) trailing only moves on your closing balance; intraday trailing follows your unrealized highs, which is stricter. Apex lets you pick EOD or intraday; Topstep, MyFundedFutures, TakeProfitTrader and Lucid use EOD trailing.
Daily loss limit
Some firms also cap how much you can lose in one day. Topstep and Lucid apply a daily loss limit on top of the trailing drawdown; Apex, MyFundedFutures and TakeProfitTrader evaluations do not.
The consistency rule
The consistency rule caps how much of your total profit can come from one day. At a 50 percent rule no single day can exceed half of your total profit, so you need at least two strong green days to pass. The calculator shows the largest day you're allowed and the minimum number of green days to clear the target.
Contracts and position size
Position size is your dollar risk divided by your stop in dollars, stop in points × the point value (NQ is 20 dollars a point, ES is 50, MES is 5). Every firm caps the maximum contracts per account, so the calculator flags when your math would put you over the limit.

Rules change. Prop firms update their evaluations regularly. These presets are kept current and verified against the firms' published rules, but always confirm the live numbers with your firm before you trade.
