Polymarket candles

Real OHLCV for every market on the venue — built from our own capture, not an API replay. 15-minute and coarser is free, full history. Every paid plan unlocks the intraday band down to 5-second bars, plus candle CSVs in your data bundles.

Trade candles are built from Polymarket's live feed as we captured it, venue timestamps, with volume in contracts. Midpoint candles are built from the top of the order book and exist wherever the market was quoted, whether or not it traded — one-sided, crossed and placeholder books (spread wider than 10¢) are excluded rather than charted. Spot prices are our RTDS capture of Binance and Chainlink. One source and one clock per series, never merged. Schema and methodology →
