// the problem

Prompt engineering for trading is broken.

// PROBLEM_001 DEMO_BURN

You wrote a prompt. Is it good? You won't know until you've burned 2 weeks on demo.

cost: 14 days × spread · feedback loop: lethal
// PROBLEM_002 ITER_TIME

Tweaking 5 prompts means 5 weeks of waiting — and most of them won't even be worth shipping.

throughput: ~1 prompt / week · throwaway rate: 80%
// PROBLEM_003 NO_AB_TEST

There's no way to A/B test a trading prompt today. You're flying blind on the most important variable.

// why trust this

Same agents. Same logic. Real backtest.

Prompt Lab runs the exact same Bull / Bear / Judge / Decision pipeline that ships inside our Expert Advisor.

The numbers you see in the lab are the numbers you'll get in production. No simulator gap. No "well, the live LLM behaves differently." Same model calls. Same arbitration. Same execution rules.

Built on a verified foundation.

Anonymous quotes from closed-beta testers running the same pipeline live.

Saved me 6 weeks of demo testing. I shipped two prompts in a weekend that I'd have killed on a live account otherwise.

The A/B compare is the killer feature. I finally have a number telling me which prompt is actually better — not a vibe.
RK
— R.K. Systematic XAUUSD · 2 years
Same Sharpe in the lab as on my forward-test demo. That's what convinced me — no simulator gap.
