Strategy Backtest

Prove a strategy's edge over decades of real history — computed metrics and sample trades.

GET/api/backtest

StrategyIncluded in every plan · one key.

Overview

Run a real, rules-based historical backtest of any strategy over Yahoo daily bars (SPY back to 1993; other symbols as available) and get computed performance metrics plus the most recent sample trades. Every number is calculated from the simulated trades — never invented. All 10 strategies are backtestable: most run a single-symbol engine, Momentum Breakout runs a 42-name universe backtest, and Supertrend Market Regime is backtested as a 'trade-the-regime' rule (long SPY while RISK_ON). Metrics are decimals (0.0131 = +1.31%). Pass ?strategy=<id>; optionally ?symbol=, ?from=YYYY-MM-DD and ?to=YYYY-MM-DD to change the instrument or window.

Use it toValidate a strategy's edge over decades of real history before trusting today's signal.
