Prop firm challenge simulator

What are your real odds of passing a prop firm challenge?

Most challenges are lost to daily loss limits and trailing drawdown, not bad trade ideas. Enter how you trade and we replay the challenge 1,000 times under the firm's rules.

1. Challenge

Phase 1 then Phase 2. Static max loss from the starting balance.

Phase 1

Target $10,000 · max loss $10,000 · daily loss $5,000

Phase 2

Target $5,000 · max loss $10,000 · daily loss $5,000

Preset rules were checked against the firms' sites in November 2026. Firms change rules often — always confirm with your firm and use Adjust rules if anything differs.

2. How you trade

Risk $500 per trade on a $100,000 account.

How the simulation works

Each simulated challenge draws trades at random from your win rate and win/loss size (or from your real trades). It checks the daily loss limit after every trade, moves the trailing drawdown the way the firm does (at the close, or during trades for intraday trailing), and stops trailing once it reaches the starting balance. For intraday trailing we assume a losing trade first shows 0.5R of open profit before stopping out. You pass only after hitting the target, the minimum trading days and any consistency rule. Results are repeatable: the same inputs always give the same numbers.

Research tool, not investment advice. Past patterns do not guarantee future results.

Why most traders fail prop challenges

Daily loss limits

One bad morning can end a challenge even when your overall edge is positive. Bigger risk per trade makes a losing streak hit the daily cap sooner.

Trailing drawdown

On trailing accounts the loss line moves up with your profits, so the room you have shrinks just as you start winning.

Order of results

The same win rate can pass or fail depending on when losses land. Only replaying thousands of sequences shows your real odds.
