Relationship to Markets

• assetPriceTerms.asset on a crypto market is the assets value to chart against.
• An Up/Down market’s priceToBeat is the simple average of the 60 one-second prices from 59 seconds before windowStart up to and including windowStart itself, the inclusive interval [T − 59 s, T]; its settlementPrice is the same statistic at windowEnd. The reading exactly at the boundary is part of the average and the reading 60 seconds before it is not. To reproduce it, query bucket=ASSET_PRICE_BUCKET_1S with from = T − 59 and to = T and average the 60 close values. For cpc-btc-updown-15m-2026-09-21-0015z, the candles from 00:14:01 to 00:15:00 inclusive average to the published priceToBeat of 81650.14; the minute 00:14:00 to 00:14:59 averages to 81649.14 and does not match.
