When one bar holds both your stop and your target, we drop to the minutes and measure which came first — rather than picking a rule and hoping. How it's graded

  1. QuantParadox says: Tell me a strategy in plain English — or bring the code you already trade — and I'll turn it into something you can actually test.
  2. QuantParadox says: Then I run it across 10 years of real data and show you where it works and where it quietly falls apart — sessions, market structure, liquidity sweeps, volatility regime and more. What do you trade?

This is what training looks like.

A GOLD idea started at −42.0% across 222 trades. Two supervised passes later — a pattern filter, then the New York session — it cleared break-even. We show you the losing runs because the last number is only worth something if you can watch it earned.

And the engine still won't call it proven: four unseen trades is not evidence, and the filters that earned the gain cut the sample to 17. Improving and unproven are different words here.

A tool that only shows winners is a guru in a lab coat.

The condition engine

Six lenses on your edge. Most backtesters have one.

Most backtesters replay price bars and call it a test. Ours runs your strategy through the conditions that actually move markets and shows you exactly where your edge lives — and where it quietly bleeds. Then it grades the result out-of-sample, with fills that never flatter, so a pretty curve can't sell you a losing strategy.

SESSIONSTokyo, London, New York — when your edge actually fires.
TREND & REGIMETrending, ranging, or coiled — tested in each, never averaged away.
USDXThe dollar index's direction as a filter on every result.
CURRENCY STRENGTHWhich side of the pair is doing the moving.
VOLATILITYCalm, normal, wild — the regime your stops actually live in.
LIQUIDITY & STRUCTURESweeps, walls, ranges — where the market actually turns.
You type

“Buy when RSI drops below 30 and price is above the 50 EMA.”

The brain does the rest
  • Compiles it into a real, testable strategy
  • Finds the conditions where it actually works
  • Suggests one-click filters — and proves each one
  • Re-runs the honest proof on every improvement
No AI experience required

Train AI on your strategy — by describing it.

Applying AI to a trading strategy used to mean data pipelines, notebooks and a machine-learning background. Here it's one interface: describe your idea, and the brain trains on it, improves it, and proves the result. No AI experience. No code. No data science.

Burned before? Good. Audit us.

Why you can trust the number.

Out-of-sample, always

Every verdict is graded on data the strategy never trained on. In-sample results are a rehearsal, not proof.

Fills that never flatter

When a bar could have hit your stop or your target, we assume the stop. We'd rather understate your edge than sell you a fantasy.

It doesn't repaint

What the engine says about a bar is only what it could have known at that bar. A read that improves with hindsight isn't a read.

Your strategy stays yours

Build it or import it — it's yours. We don't trade it, publish it, or sell it to anyone else.

Live is off by default

Nothing here switches on real money for you — not the AI, not us. You arm it, on your own broker, or never.

An honest verdict

Deployable, promising, improving, or reject — whatever the numbers say. Most simple strategies get rejected. That's the point.

We sell no signals, no strategies of ours, no borrowed track records. If your edge isn't real, this product will tell you.
