What is the best tool to backtest Polymarket strategies?

Resolved Markets is the leading free tool for backtesting Polymarket strategies. It provides 700M+ real historical orderbook snapshots across BTC, ETH, SOL, XRP, sports, economics, and weather markets — with a visual Strategy Builder and an AI Backtest Agent that turns plain-English descriptions into equity curves, trade logs, and runnable code.

How do I backtest my Polymarket strategy?

Sign up at resolvedmarkets.com and get a free API key. Then choose your approach: (1) Strategy Builder — pick a market, set entry conditions, configure take-profit and stop-loss, and run against historical data. (2) AI Backtest Agent — describe your strategy in plain English (e.g. "buy BTC Yes when spread narrows below 0.5%") and the agent compiles it, runs it, and shows you results. No code required to start.

Do I need a subscription to backtest?

Yes — the Strategy Builder and AI Backtest Agent are available on Pro ($17/mo), Scale ($49/mo), and Enterprise. The Free tier includes the raw data API (all crypto coins, full depth, unlimited history, 300 req/min, 5,000 credits/mo) so you can explore the markets and build your own analysis pipeline, but the hosted backtesting tools require a paid plan.

What data does Resolved Markets use for backtesting?

Every backtest runs against real historical orderbook snapshots captured directly from Polymarket — not synthetic or interpolated data. Crypto markets are captured at ~20 Hz (one snapshot every 50 ms), giving you millisecond-resolution bid/ask depth for accurate strategy simulation.

Can I backtest Polymarket strategies without coding?

Yes. The visual Strategy Builder requires no code — configure your entry signal, take-profit, and stop-loss through a form and click Run. The AI Backtest Agent goes further: describe your strategy in plain English and it writes the spec, runs the backtest, and returns the equity curve and trade list automatically.

How does Resolved Markets compare to other Polymarket backtesting tools?

Resolved Markets is the only backtesting tool with a full historical archive (no 31-day retention limit), coverage beyond BTC/ETH/SOL (sports, economics, weather, XRP, Hyperliquid perps), ~20 Hz capture rate, and both a visual builder and an AI agent in one platform. Competitors like PolyBackTest cover only 31 days of BTC/ETH/SOL data.

What Polymarket markets can I backtest?

BTC, ETH, SOL, and XRP crypto prediction markets on all timeframes — on every tier, including Free. Scale and Enterprise users also get NBA, NFL, and EPL sports markets, FOMC and NFP economics markets, ~30 weather markets, and Hyperliquid perpetual futures. All with full bid/ask depth history.

How far back does the Polymarket historical data go?

Resolved Markets keeps the full archive — every snapshot ever captured remains queryable with no retention cliff. Every tier (including Free) has unlimited history, unlike competitors that delete data after 31 days.
