Built to find real edge
Every feature points at one outcome: strategies that hold up out of sample.
Genetic strategy evolution
A genetic engine breeds and mutates thousands of NinjaTrader 8 strategy variants to search for genuine, durable edge — not luck.
Rigorous validation
Walk-forward, out-of-sample and robustness checks separate real edge from curve-fit noise before anything reaches your charts.
A clear verdict
Every finalist earns an evidence-backed verdict and a ranked leaderboard, so you know what survived and why.
Built for NinjaTrader 8

Questions, answered
Does it work offline?
Yes. The hot path is fully local and your license verifies offline for about 21 days. Reconnect occasionally and it renews silently in the background.
How many devices can I use?
Your subscription includes 2 platform-agnostic seats — any mix of Windows and macOS. You can deactivate a device from your account at any time to free a seat.
Is my strategy data private?
Your builds and runs back up privately to your own account so you can restore them. Only you see them in the app; the operator can access them for support and backup. Other customers never can, and your local market data never leaves your machine.
Is there a free trial?
No — it is subscription-only. Billing is handled by Lemon Squeezy as merchant of record, and you can cancel anytime; the app keeps working until the period ends.
Which platforms are supported?
A Windows and macOS companion app builds and validates the strategies; NinjaTrader 8 itself runs on Windows.
