> 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.
> 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.
