Trading systems for people who read the backtest.

Open-source ML tools and commercial trading software, built by engineers who have shipped production data science for Walmart, Fiat-Chrysler, Deloitte, and Fidelity Information Services.

The Approach

What you’ll see, what you won’t.

Hypothesis first

Strategies start as ideas, not backtests. We design the signal first, validate second.

Walk-forward only

No single-split train/test curves on this site. Every result is held forward in time.

Costs included

Published results include slippage, commissions, and the out-of-sample window.

Post-mortems shipped

If a strategy breaks, we publish the post-mortem. Survivorship bias is the enemy.

Audience

For systematic traders who want to read the code before they trust the curve.
