The rule is visible before the fee.
PropSurvival exists so a trailing drawdown or a consistency clause is a number against your own trades before you pay the evaluation fee. Each of the 60 firm rule sets in the live corpus has a dated source record; 41 retain unresolved historical citation findings and await re-verification. Gaps print "not recorded", never a guess. Every correction is dated and public on the changelog.

An evaluation fee is charged while the rule is still prose on a firm's site. Trailing drawdown, a consistency clause, a daily-loss reset — published, but not yet a number against your trades. The shape of the constraint arrives after the money has moved. PropSurvival reverses that order: run your own inputs against the written rule, locally, before the fee.
How the numbers are made
The simulation engine and the rule corpus are built by the same operation — not a scraped leaderboard, not a forum table, not a marketing summary of someone else's list. How a field is sourced, labelled, and rechecked is on research-methodology.
Source verification is dated and scoped. A firm's own page is read and stored with the date. A recheck records which account and fields were compared with the primary source; confirmation applies to that scope. Disagreement is the record. When a fact cannot be sourced, the field prints "not recorded" rather than a plausible fill-in. The browser engine keeps trade history, imported CSVs and locally generated reports on your device. Separately, the site records anonymous page/event requests, and explicitly invoked AI/plugin or decision-API features send selected rule/scenario fields for that request; see our Privacy Policy. That method covers the live corpus of 60 firm rule sets across 247 account-size configurations, with the newest corpus-wide last-checked date 2026-10-15. Per-field dated receipts stay on the changelog — the same receipt the rest of the site uses.
The method governs what the numbers may say. PropSurvival is an independent simulator of published evaluation rules — not a prop firm, not a broker, not signals, not investment advice. No rankings. No affiliation. No outcome, pass, or payout promises.
How fresh the data actually is
As of 2026-10-15, PropSurvival's freshness ledger retains unresolved historical citation findings for 41 of its 60 tracked firm rule sets. Those earlier reads recorded that the cited passage could not be found at that time; this count does not assert that every passage is absent today. A completed scoped field check does not clear these findings or establish whole-plan currency. The stored values remain recorded, with unresolved terms held for re-verification rather than silently treated as current. Re-verification remains pending until a complete review confirms or corrects the unresolved terms.
Published and maintained by PropSurvival
PropSurvival is responsible for the rule data, simulation software and correction record. Source readings and automated checks are recorded separately, with the account, date and scope they cover.
See the sources and calculation scope for the Personal examples and user-defined limits. Corrections are dated in the changelog.
Product principles
Published sources, explicit assumptions and dated corrections make the work checkable. When an account term cannot be established, the result shows what is missing. The model does not promise a pass or payout.
What's next
Want to see it work rather than read about it: run your own trade history against limits you set, or against a firm's published rules, free. Start at the personal rules simulator or the prop firm simulator; the browser simulation runs locally (see Privacy for separate anonymous site events and optional AI/API requests). Prefer the mechanism first: provenance, confidence labels, and dated verification records are at research-methodology.
