Pipeline

This dataset is produced by polymarket-data-pipeline, which runs three services:

Historical scan (every 6h): pages through Polymarket's Gamma API for closed markets, fetches CLOB price history, and backfills on-chain tick data from Polygon.
Live WebSocket (24/7): captures real-time trades, orderbook BBO, and spot prices.
Upload (every 3h): consolidates shard files and pushes to this dataset.
