Outgrown the built-in Strategy Builder?
NinjaTrader 8 ships with a free point-and-click Strategy Builder — a solid way to assemble one idea without code. Verdict Strategy Builder starts where it stops: a genetic engine generates hundreds of candidates, validates them out of sample, and hands you a ranked shelf instead of a single guess.
Launch offer — first month $44.99 (then $59.99/mo), or $499 your first year (then $575.90/yr).
Same destination, different road
Both roads end in a NinjaScript strategy running in NinjaTrader 8. The difference is everything before that. In the built-in Builder, you are the strategy: you supply the hypothesis, pick each condition, wire each action — and when the backtest looks good, it’s still one hand-made idea whose robustness you have to judge yourself.
Verdict Strategy Builder treats strategy-making as a search problem. You choose which indicators, filters, entries, exits and risk rules are allowed; the genetic engine breeds and mutates hundreds of complete strategies from those blocks, tests every one out of sample, and stamps each with a Pass, Marginal or Kill verdict. What reaches you is a ranked leaderboard of survivors — each exportable as the same kind of standalone .cs you’d have written by hand.

The built-in Strategy Builder is free, made by NinjaTrader, and exactly right for a first hand-built strategy. Verdict Strategy Builder is for the day you want breadth of search and a verdict — not another single hand-assembled guess.
Strategy Builder vs Verdict Strategy Builder, answered
Is Verdict Strategy Builder part of NinjaTrader?
No. Verdict Strategy Builder is an independent desktop app and is not affiliated with or endorsed by NinjaTrader, LLC. It exports standard, standalone NinjaScript (.cs) that compiles in NinjaTrader 8 like any other strategy file.
Do I need the built-in Strategy Builder to use it?
No. You import the exported .cs into the NinjaScript editor and compile — the built-in Strategy Builder isn’t involved at any step.
Can I edit an exported strategy afterwards?
Yes. The export is plain, readable NinjaScript with no obfuscation and no runtime dependency on our app — it’s yours to modify like anything you wrote by hand.
Do I need to write code?
No. You define the search space with point-and-click blocks; the engine writes and tests everything. Code only enters the picture if you choose to open the exported .cs.
The Strategy Builder compared above is the strategy-construction tool included in NinjaTrader 8, made by NinjaTrader, LLC. NinjaTrader® and NinjaTrader 8® are trademarks of NinjaTrader, LLC — Verdict Strategy Builder is independent software, not affiliated or endorsed. Details are as of July 2026.
