Know where you stand before you risk the account
The simulator is free and complete — your book against your own rules or a firm’s published ones, the full verdict. The paid files are for when you want that reading stamped, kept, and reproducible. First, read what a prop firm challenge really costs.
On your own capital
Your rules, your book.
The free run models the limits you set and names which one breaks first. The $49 Personal Case File — one-time, yours to keep — is where that strategy's decision system starts: eight sections, your Risk Constitution among them, and the full reading stamped and reproducible from the seed.
Run your book — free →Inside a prop evaluation
A firm’s published rules.
The free run models your book against any of 60 firm rule sets · 247 account sizes. The $29–$249 files go deeper on an account already in progress.
Run a firm’s book — free →We shipped the product before the payment button — and the free tier stays free and complete.
Your trades, balances and results never leave this device — a buy button is a link, not a transmission. Every sellable tier below links its own full sample — real engine output on a disclosed illustrative account. Read the real document before you decide.
What an evaluation costs is not its fee.
| Evaluation fee | F · your firm's price |
|---|---|
| Probability of passing | P · your own run |
| Expected attempts | 1 ÷ P |
| Expected total outlay | F ÷ P |
No pass probability here, ever — that belongs to your history against one firm's rules, not a price list. The free tier computes P from your own trades; the two divisions above are yours to do. The $99 file does them for you across four reset-or-continue branches, fee schedule and seed on the page.
The files
$29 — Where you stand TODAY — a snapshot of the account in your hand; snapshots go stale, so it grants one month.
$49 — Your full case file — 8 sections, the sweep study, stamped; yours to keep.
One bad day, mid-evaluation
Something went wrong — where do I actually stand?
A one-time diagnosis of the account you are holding right now, stamped and exportable. One payment, one month of access, and nothing to cancel.
Trading your own capital, not a firm’s? The $49 Personal Case File is yours to keep — no month, no renewal.

Trading to your own rules, not a firm's
Can I actually hold to my own rules — and where would they break first?
Where your strategy's decision system starts: eight sections — your Risk Constitution (the rules you chose, attested) among them — and the full sweep study, stamped and reproducible from the seed. The free run models a strategy from zero; this file records where yours stands today, so any later run can be compared against it.

Why these two renew: corpus re-verified — regenerate your document against the refreshed corpus anytime in your year. (60 firms / 247 rule sets.)
Inside a live evaluation
Can I still pass — and should I reset or continue?
The full eight-section case file on a live evaluation, rebuilt as often as you like. When your firm's reset fee is on file, the report opens with the modelled cost of continuing versus resetting, in dollars, computed from your disclosed account state.

Five or more accounts, or a desk
Evaluating this for more than one account?
Tell us the shape of it — how many accounts, which firms — and we reply. This row prints no number: it is an inquiry, never an offer.
How many of the twelve questions does each tier answer?
Read from the firm's own document
Every firm preset is transcribed from that firm's own published rulebook and carries the date it was read. Where a firm's wording does not settle a field — for some firms, whether a drawdown floor tracks the intraday peak or the end-of-day balance — it is recorded as unresolved and the run names that field for that firm, rather than choosing quietly. The firm's documentation is always the final authority: we model it, we do not rank it.
Your trade data never leaves your device
The engine runs entirely in your browser. Your trades, your balances and your results are never uploaded, because there is no server to upload them to. Turn on airplane mode and run a full analysis — that is the audit, and it takes about four seconds.
A stamped run, not a screenshot
Every run records the firm, the date its rules were read, the number of paths and the seed. Feed the same inputs to the same rules and the same numbers come back — which is what makes an exported file worth sending to anyone. That is the difference between an instrument and a dashboard.

The Personal Case File is scored against rules you set yourself, not a firm's — it is deliberately not a column here; see its card above.
Contents
What is actually in the file
Not a feature list — the sections a finished document contains. Each one is a computation with its inputs stated, so you can disagree with it on the arithmetic rather than on the vibe.
Six sections, read from the state you enter — one honest reading of the account in your hand.
- Coverage first. How many payout conditions we've verified for your firm, named and dated, before anything is ruled on. Zero means zero — silence is never read as "you're clear."
- Where you stand against each condition, with the two numbers behind it, and the one binding right now named.
- Your consistency ratio — largest day over total — against the published limit, or the one you enter where there isn't one.
- What clearing it takes: the profit still required, solved exactly, and the simulated days to reach it — median and 90th percentile.
- The payout window and the days to it — a date is not a payout unless you qualify by then.
- Full disclosure: the formulae, the firm's own words with retrieval dates, the seed and path count. Stamped, exportable PDF.
Eight sections on a live evaluation, rebuilt as often as you like.
- The verdict, and the one rule that killed the most paths — with its share of all deaths.
- Full failure breakdown, dominant cause first, summing to 100% — nothing quietly left out.
- The risk level where the modelled funded-probability peaks — a number, not an adjective.
- Attempts & cost: how many this implies and their expected reset-fee cost. What you've already paid isn't counted twice.
- Reset or continue, priced both ways across four branches — both figures shown, no verb telling you which.
- Provenance: corpus version, seed, paths and standard error — run it again, get the same answer.
Everything in the Case File — plus the questions that only start after you pass.
- Payout-eligible? If not, the exact gate holding it up — named, not implied.
- Consistency cap: the profit still required and the simulated median days to clear it.
- The next payout window and the days until it.
- Every funded account read together, not one at a time.
Terms
What you keep
- The free tier is permanent and complete — not a trial; nothing free today ever moves behind a paywall.
- $29 Situation Report — a one-time payment, one month of access. It does not renew; nothing to cancel.
- $49 Personal Case File — a one-time payment, yours to keep. No renewal, ever.
- $99 Case File and $249 Funded File are annual and renew. Terms are published, not pending (Terms §5); stop a renewal any time before its date, from your purchase email.
- A licence covers 2 devices; 14-day refunds on any paid purchase.
- A licence has a term; your files do not. When it ends, only new-document generation stops — the files you already made stay on your device, readable. Measured, not assumed: an ended licence drops to read-only.
Payments are processed by Gumroad, our merchant of record — your trade data is never part of that transaction.
Privacy
Where your data lives
Everything you enter — trades, balances, results — stays in your browser's storage and is never transmitted. Clear your browser data and it's gone; we can't recover what we never had. The in-app export is your backup, not our server.
Only two things ever leave your device: a licence key when you activate one, and the email you use at checkout. Neither carries any trade data.
