Quanterlab

QuanterLab is a research platform for testing trading strategies on historical data. Connected to Claude, it runs backtests and walk-forwards on your QuanterLab account, tracks a strategy live as a paper trade, and reads the research studies QuanterLab publishes.

Ask Claude to:

• test a rule you describe in words, such as buying SPY when its 2-day RSI falls below 10, over 30 years, and show how it did against simply holding SPY;
• run a walk-forward on it, which re-fits the settings on each window and tests them on the next, to see whether an edge holds outside the period it was tuned on;
• run a published study's own strategy and change one of its settings;
• start a strategy live as a paper trade, with a note on it every morning;
• scan an index for mean-reverting stocks or cointegrated pairs, and test OU and Kalman models;
• list and summarise your saved tests, paper trades and projects;
• search QuanterLab's published studies and quote them with their links.

Every new account starts with 30 days of Practitioner, free and with no card, so all of this works from the first day.

The connector places no orders, connects to no broker and moves no money. Tests are simulations on past data and paper trades use no money; results come back as summaries, and raw prices stay on the platform. Nothing it returns is investment advice.
