propability

Know the odds before you buy the challenge.

Most prop-challenge attempts fail. Propability puts your own trading stats against your firm's actual rules and shows you the full distribution of outcomes — before the evaluation fee leaves your pocket.

Free account. The math is fully disclosed — descriptive probabilities, never advice.

The fee buys one draw. We show you the deck.

If your pass probability under a firm's rules is 10%, the expected cost of getting funded isn't one fee — it's ten. That arithmetic is invisible on every pricing page in the industry. Making it visible, for your exact statistics, is what Propability is for.

Three steps, no black box

  1. Your statistics. Win rate, average win and loss, risk per trade, trades per day — five numbers you already know.
  2. The firm's exact rules. Dated presets encoding targets, drawdown mechanics, daily limits, consistency, and time rules.
  3. 10,000 simulated attempts. The full distribution: pass probability, which rule ends attempts and when, and how it all shifts with sizing.

Read the complete methodology — it fits on one page.

See the whole distribution

Not one guess — 10,000 simulated attempts of your stats against the firm's exact rules, with pass, fail, and timing laid out honestly.

The firm's real rules, dated

Daily loss, static and trailing drawdowns, consistency, minimum days — encoded per program, stamped with an as-of date, never changed silently.

Results worth sharing

Every simulation exports a clean card with server-verified numbers — the screenshot you'd post anyway, unfurling beautifully on Discord and X.

Built for the decision, not the dopamine

Whether it's your first evaluation or your fifth, the useful moment is the ten minutes before you pay: compare the rulebooks, look at worked examples, run your own numbers, and buy — or don't — knowing the distribution you're stepping into.

Propability is an educational analytics tool. Educational simulation of user-entered parameters — not investment advice. Outcomes are descriptive probabilities of the scenario you defined, not predictions. Firm rule presets are dated and may lag firm changes — always confirm rules with your firm.
