Resolved Bitcoin 15m 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 15m windows work

Every Bitcoin 15-minute window opens at :00, :15, :30 or :45 UTC and closes 900 seconds later, 96 windows a day with no gap between them. The price to beat is the spot price at the quarter-hour boundary and does not move once the window is open.

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 15-minute window holds roughly 3 times as many recorded points as a 5-minute one.
