About this site

QuantDojo exists because most trading "edges" are statistical illusions.

Open any forum and you'll find strategies, signals and generators sold on the strength of a beautiful backtest. Most of them are noise dressed up as skill — overfit, survivorship-inflated, or quietly reading tomorrow's prices. The maths that separates a real edge from luck is well known in academia and on institutional desks. It almost never reaches the retail trader.

That's the gap QuantDojo fills. Our promise is simple: we test what others sell.

What we do

• Tools — starting with quantcheck, a free, no-code way to check any backtest for overfitting (Deflated Sharpe Ratio, PBO, bootstrap), plus a paid Deep tier with institutional-grade data-snooping tests.
• Experiments & research — hands-on, show-me-the-math articles where we put popular strategies, indicators and claims through a proper test and report the honest result.
• No hype. No "90% win rate" screenshots, no guru promises. Just the numbers, and what they actually mean.

The one principle

Every clever validation method — Deflated Sharpe, PBO, Reality Check — only tells the truth if the data and the search behind it are honest. Get those right, then validate. That discipline is the whole dojo.

Who it's for

Systematic and algorithmic traders, strategy builders and buyers, and anyone about to risk real capital — or a prop-firm challenge — on a backtest.

Everything here is for education and analysis. Nothing on QuantDojo is financial advice.
