5,000 futures
A Monte Carlo fan of 5,000 futures against one rulebook — not your CSV. Paths stop at a rule or the profit target; the wine line is the trailing floor, which only rises.

Inconvenient, and true to the data: firm-count 60 is not ruleset-count 247 — conflating them invents a third figure. Ranges stay ranges; unresolved stays unresolved.

Citable answer
Quick answer: A trading account ends on a written rule — drawdown, daily loss, consistency, horizon — not on strategy. PropSurvival compiles the book you wrote, or a firm’s published clauses (60 firm rule sets / 247 account-size configurations), into arithmetic, runs your own trade history against it in the browser, and names the constraint that binds first. The dated public receipt for every firm last-read is the Rule Changelog. The free verdict stays free; paid documents ($29 / $49 / $99 / $249, see pricing) deepen an account already in progress without changing free accuracy. Run your book — free. Three studies open that path: funded account rules (14.2%–75.2% funded death among profiles one evaluation grades within 2%), two-step challenge probability (64.9%→70.5% conditioned), and broker export to expectancy (51.5% vs 65.2% win rate on the same $605.50).

Is this just another prop calculator?
Free calculators take typed averages and shuffle them against a static drawdown. This engine imports your actual trade history, applies the written rulebook — your limits, or a firm’s real drawdown mechanics (intraday trailing vs. EOD vs. static, freeze-at-initial, consistency rules) — decomposes failure by cause, and computes the risk band that changes the outcome. It is a Monte Carlo rule-survival engine, not a tick-level chart replay. Run the free analysis — nothing is uploaded.
Can a simulation really predict whether I'll pass?
No. Monte Carlo gives you the probability distribution your statistics imply under the firm's rules, assuming your future resembles your sample. What it does well: showing when the fee is mathematically premature, and which lever moves your odds most.
What happens to my trade data?
It is parsed and stored inside your browser only. There is no server that could receive it. Two things can leave the device, and only these two: a licence key if you activate one, and an email address if you type one into a form.
Is PropSurvival free?
The verdict engine is free and always will be — every firm in the corpus, a 2,000-path Monte Carlo with no accuracy gate, the Firm Fit comparison, CSV trade-history import, and your run history, with no signup and no card, entirely in your browser. Four paid tiers ($29 / $49 / $99 / $249, see pricing.html) add deeper documents for an account already in progress; none of them change the free verdict's accuracy.
Can I reproduce a result later?
Yes. Every run records the firm, the date that firm's rules were read from its own documentation, the number of paths and the seed. Given the same inputs and the same firm rules, the model returns the same numbers. That is a property of the engine, not a claim about the market.
What happens when a clause is ambiguous?
It is recorded as unresolved rather than guessed. Where a firm's own worked example does not settle a field — for instance whether a drawdown floor tracks the intraday equity peak or the end-of-day balance — the run says so next to the verdict and points you back to the firm.
There are thousands of possible futures.
The rules narrow them.
One constraint usually matters more than the others.
