Embeddable Widgets

The one-sentence version: two of PropSurvival's calculators run as free, iframe-embeddable widgets on your own page — the exact same Monte Carlo engine as the full site, not a simplified stand-in, so a number shown here is the same number the full tool would show for the same inputs.

1. Why the number doesn't drift

Most free prop-firm calculators model a static drawdown floor because it is simpler to build — and on identical trading statistics that can report a materially higher pass probability than a rule-faithful trailing-drawdown model, because a static floor can't be hit by a retracement from an unrealized equity peak. This site's simulator runs the real trailing mechanic against the actual per-firm rule corpus, not a static-floor approximation; see the static-vs-trailing drawdown study for how large that gap can get. The two widgets below are pulled directly from the same source the main app builds from — propSimCore, runPropAtRisk, propVerdictOf, the per-size rule lookups, the full firm rule corpus — never reimplemented by hand. A number shown here will not quietly drift from the number the full tool would have shown for the same inputs.

2. Static vs Trailing Drawdown

Five inputs — win rate, average win, average loss, risk per trade, account size — run through one trader profile twice: once under a static drawdown floor, once under an end-of-day trailing floor locked at the starting balance. Both runs share a single seeded random stream, so the comparison isolates the floor mechanic itself rather than sampling noise. Target, drawdown percentage and day window are fixed to typical single-step challenge terms, stated on the widget itself.

Measured content height after a run: about 675px at desktop widths, up to roughly 1030px at 320px wide — size the iframe for the narrowest width it will actually render at, or a little tall.

3. Prop Challenge Verdict

Pick one of the corpus firms or programs, enter six trading stats — account size, risk per trade, trades per day, win rate, average win, average loss — and get the same GO / WATCH / REDUCE RISK FIRST / NO-GO verdict, pass probability, binding failure cause and modeled safe-risk band the full tool's own Challenge Verdict panel computes for that firm's published rules. No firm selected, no number shown: a pass probability is a property of one firm's rule set, not a generic template standing in for it.

4. Using either widget

Both are static HTML with one inlined script each — no external requests, no cookies, nothing fetched from the host page. No account, no API key, no paid tier, no gating: this is a free distribution surface, not a lead-gated one. Every result already carries a small "via PropSurvival" link back to the source page (target="_blank" rel="noopener" — it never navigates the host page), which is the only attribution either widget asks for.
