## Citable answer

A prop firm simulator, on PropSurvival, is a free in-browser Monte Carlo of the trader's own statistics against a firm's published evaluation rules — trailing or static drawdown, daily loss, consistency, time window — across 59 firm rule sets and 243 account-size configurations. It reports a pass probability for a stated profile and the rule that binds first. It is not a tick-level chart replay, not a prediction of a specific outcome, and not a ranking of firms.

## What it is

- Monte Carlo of the trader's own win rate, average R, and risk size
- Against dated, sourced published rules (source URL, quote, retrieval date per field)
- Static, end-of-day-trailing, and intraday-trailing drawdown with freeze-at-initial
- Daily loss limits and consistency / best-day rules
- Seeded, reproducible; nothing the user enters leaves the device
- Free, no signup

## What it is not

- Not a tick-level ES/NQ/forex chart replay
- Not a promise that the trader will pass
- Not investment advice
- Not affiliated with any prop firm
- Not a ranking of firms
