Three ways people use BackTestable
What you get
The history was always there. Now you can trade on it.
Know before you trade
Search 50,000+ resolved markets by category, price range, and outcome. See exactly how markets like yours have resolved.
Backtest the setup, not your gut
Price cap, time to close, volume floor, category filter—run your entry rules against years of closes and get win rate, P&L, and calibration in seconds.
Calibration you can trust
See when the market was right, when it was wrong, and which categories are systematically mispriced. Trade the gap, not the narrative.
Data that leaves the browser
REST access to resolved markets, price curves, and outcomes. Webhooks when you need a feed, not another dashboard.
