Polymarket up-down markets, one file per source per day

Every message as the collector received it, or folded to one row per second — parquet either way, with a microsecond receive timestamp. Binance, Bybit, OKX, Coinbase and Chainlink for the same coin come on the same clock — and come with the market you buy.

Raw

The full Polymarket feed exactly as the collector received it, stored as parquet: one row per message, with its microsecond receive timestamp. A day arrives as the Polymarket market plus the exchange files for the same coin, all on one clock.

Aggregates

The raw parquet folded down to one row per second: open, high, low and close of the mid price and of the trades, volume, the best bid and ask and the top ten levels of the book on each side. Built from the raw files of the same day, and every file records the sha256 of the one it came from.

How it works

  1. Pick days. One market, a continuous range on the calendar. Add as many ranges and markets to the cart as you like.
  2. Pay in crypto. The order link works before and after payment — it is your download page.
  3. Sync with one command. The script fetches what you do not have, resumes after a break and verifies every checksum.
