Most evaluations don't die to bad strategies — they die to trailing drawdowns, daily limits, and oversized risk. PropSurvival runs your real trades against each firm's real rules and returns a probability-backed verdict: your funded odds, the exact cause of failure, and the risk band that keeps you alive — before the fee leaves your card.
No signup. No upload. Your trade data never leaves this browser tab — disconnect your internet and it still runs.
Drop a CSV export from your platform — or type your win rate, average R, and trade frequency. No sample-size theatre: the engine labels the statistical confidence of your inputs.
One click loads the firm's actual rule set: intraday vs. end-of-day trailing drawdown, freeze-at-initial floors, consistency percentages, daily loss limits, time windows. Every preset carries a "last verified" date.
Thousands of Monte Carlo paths return your pass probability, the exact cause of failure, your Survival Score, and the risk band that keeps you alive. GO, REDUCE, or NO-GO — before you pay.
A 6% trailing drawdown computed on intraday equity peaks is a different game from a static 10% floor — and most traders discover the difference after the account is gone. Every preset below is modeled the way the firm actually measures it.
Static drawdown: the same dip survives, because the floor stays where it started.
Trailing drawdown: the identical dip is fatal — the floor climbed with your unrealized peak.

Rules change without notice — every preset shows its verification date inside the engine, every update is logged publicly on the rule changelog, and Pro licenses receive rule updates for the life of the product. Always confirm final rules on the firm's own documentation before purchasing. Deep dives: Apex trailing drawdown, explained · Topstep's 50% consistency rule · prop trading glossary.
PropSurvival is a single self-contained page. There is no backend, no database, no account system. Your CSVs are parsed in this tab, simulations run in this tab, results are stored in this browser's local storage — full stop.
Trading journals charge $348–588 every year. The nearest tool with a comparable simulator gates it at $349. PropSurvival is $39, one time — because its job is to protect the $300 you're about to spend, not to become a second subscription.
Checkout and license keys are handled by Lemon Squeezy, our merchant of record — they collect VAT/sales tax and hold card data; we never see either. Refunds are 14 days, no questions asked, from your purchase email. The launch price is $39 for the first 50 licenses, then it moves to $49 — a public commitment, not a countdown timer. Early buyers keep their price through every future update.
The free calculators take your typed averages and shuffle them against a static drawdown. This engine imports your actual trade history, applies the 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. Run both on the same stats and watch the numbers disagree — that disagreement is the product.
No — and anyone who says otherwise is selling something. Monte Carlo gives you the probability distribution your statistics imply under the firm's rules, assuming your future resembles your sample. It cannot know regime changes or your psychology. What it does brutally well: showing when the fee is mathematically premature, and which single lever (usually risk size) moves your odds most.

Every preset displays the date it was last verified against the firm's own documentation, and the modeling notes state every simplification openly. Rules change without notice — that's exactly why they're versioned, dated, and kept updated for the life of the product on the Pro license. Final authority is always the firm's own docs.
It's parsed and stored inside this browser only. There is no server that could receive it. Verify: open the engine, disconnect from the internet, and everything still works. The only network call the product ever makes is license activation — which sends the license key, nothing else, to the payment provider.
Because you're trying to stop paying recurring fees to this industry, not add another one. $39 is a single up-front payment — not a subscription, nothing to cancel — and it includes the rule updates we release for the product. If it saves you one bad $300 challenge purchase, it paid for itself eight times.
Your edge stays on your machine. The engine runs entirely in your browser with no dependency on our servers, so the version you have keeps working even if updates ever stop — and your Pro license is built the same way: once activated it isn't downgraded because a server is unreachable, so an outage or shutdown can't lock you out of what you bought. If we ever permanently close the product, our intention is to release a final build with the license check removed. You're buying software that runs on your machine, not renting access to a server someone can switch off.
Takes about three minutes. Costs nothing. Might save you $600.
