Resolved Bitcoin 1h windows, newest first. Price to beat is the window open Polymarket settled against (its crypto-price API), and Move is Close minus that open. A dagger marks a window where our own first Chainlink tick differed from it; a dash in Move means the move was smaller than the stored price precision.

> how Bitcoin 1h windows work

Every Bitcoin 1-hour window opens at the top of a UTC hour and closes 3,600 seconds later, 24 windows a day. Polymarket names these markets with an Eastern Time date instead of a UTC one (for example bitcoin-up-or-down-july-9-2026-10am-et), so the market name shifts across US daylight saving changes while the window itself stays on the hour.

What is a Polymarket up or down market?

> data sources

Bitcoin pages read from Pyth Hermes, Binance, Chainlink, the Polymarket CLOB order book and the Polymarket price-to-beat feed.

Sampling cadence is the same on every timeframe, so a 1-hour window holds roughly 12 times as many recorded points as a 5-minute one.
