Polymarket Historical Data

Download Polymarket Trade History CSV

Download-ready Polymarket trade history workflows for CSV research, with order book context for realistic execution analysis.

Polymarket trade history CSV is useful for notebooks, audits, and quick event studies, but trades alone do not show the available liquidity around each fill. The strongest workflow combines trades with historical order book snapshots.

Fields to Include

  • Timestamp, market slug, condition ID, token side, price, size, and trade direction.
  • Best bid, best ask, midpoint, spread, and depth near the trade time.
  • Market open time, close time, resolution status, and final winner.
  • Reference prices for BTC, ETH, or SOL markets when the underlying asset matters.

CSV vs API

CSV is convenient for one-off analysis and sharing. API access is better for repeatable backtests because you can page through market windows, align snapshots by timestamp, and pull only the depth needed for a strategy run.
