What the numbers mean

  • Chance to pass: the share of simulated attempts that hit the profit target before failing.
  • Fail on max drawdown / daily limit: attempts that touched the overall floor, or lost the daily limit within one day.
  • Not finished: attempts still running after your trade cap, neither passed nor failed.
  • Expectancy: win rate × reward:risk − loss rate, in R (multiples of your risk). Above zero means the strategy makes money on average.
  • Break-even win rate: 1 ÷ (1 + reward:risk), the win rate at which expectancy is exactly zero.

Worked example

On a $100,000 account with a 10% target, 10% static drawdown and 5% daily limit, a trader risks 1% ($1,000) per trade, wins 45% of the time and makes 2R on winners. Expectancy is 0.45 × 2 − 0.55 = +0.35R, about $350 per trade, so the edge is real. The calculator shows how often that edge reaches $10,000 of profit before a losing streak costs $10,000.

How to raise your pass rate

  • Know your real win rate. Guesses are usually too high. Track every trade in the free trading journal first.
  • Risk less than you think. With a positive edge, smaller risk per trade almost always survives longer; the table shows where your sweet spot is.
  • Respect the daily limit. Several trades a day at high risk is the fastest way to fail on the daily rule.
  • Watch a trailing drawdown. It tightens as you make money; see exactly where it sits with the trailing drawdown calculator.

Frequently asked questions

How does the challenge calculator work?

It plays out 10,000 challenge attempts trade by trade. Each trade wins with your win rate and pays your reward:risk, or loses your risk per trade. An attempt passes when profit reaches the target, and fails when the balance touches the drawdown floor or a day's losses reach the daily limit.

What win rate do I need to pass a prop firm challenge?

It depends on your reward:risk. At 1:1 the break-even win rate is 50%, so you need more than that to make money; at 2:1 it is 33.3%; at 3:1 it is 25%. Passing reliably needs a clear margin above break-even plus risk per trade small enough to survive losing streaks.

Is a higher risk per trade better for passing faster?

Higher risk reaches the target in fewer trades but fails far more often on losing streaks. With a positive edge, moderate risk usually gives the best pass rate. The comparison table runs your exact strategy at several risk sizes so you can see the trade-off.

Why are my results different from real trading?

The simulation assumes every trade is independent, and every win and loss is the same size. Real results vary: slippage, partial exits, news and emotions change the numbers. Treat the odds as a guide to how sensitive your plan is, not a promise.

Does the calculator include consistency rules or minimum trading days?

No. It models the profit target, the maximum drawdown (static or trailing), the daily loss limit and a cap on the number of trades. Check your firm's other rules, such as minimum days or consistency, separately.
