Most traders who pay for a prop firm evaluation don't pass it, and many keep retrying with a strategy that never had an edge. Prop Firm Lab is a Windows program that works with what NinjaTrader exports and answers three questions before you pay.
Windows 10 or 11 · NinjaTrader 8 to export your data · Python 3.10+ (the installer guides you)
1. Does your strategy hold up on data you didn't use to build it?
Upload the trades CSV from NinjaTrader's Strategy Analyzer, the date you stopped looking at the data and how many variants you tried. You get the out-of-sample test, the bar chance sets for that many variants and the results year by year.

2. How often would you pass each firm's evaluation?
Monte Carlo with the 50K account rules of APEX, Lucid, Tradeify, MyFundedFutures and Topstep (trailing, daily loss, consistency, time limit), and the position size that passes most often.

3. And if you pass, how much would you get paid?
A year of funded account with the payout rules of APEX, Lucid Flex and Topstep: buffer, minimum days between payouts, consistency, caps and profit split. It gives you the expected payout per evaluation you buy, to compare with what it costs.

Also included
- Strategy mining: 526 combinations of six textbook families with a test fixed before you look and a walk-forward. See what it found on the Nasdaq: mining 526 strategies.
- Export to NinjaScript (.cs) of any combination, with optional daily loss and trade limits, and a parity check against the Strategy Analyzer.
- A browser panel in English and Spanish. Your trades never leave your PC.

What it isn't
We don't give you strategies, signals or recommendations. It doesn't promise you'll pass. Often the answer will be "this has no edge", and that answer saves you money.
