How this recap is built
Source: Binance USD-M futures and spot public market data, recorded by our engine each minute and rolled up to hours. Only the BTCUSDT perpetual is read; other exchanges and contracts are not included, so this is not a total or global figure for BTC.
The price return and OI changes compare the previous day's 23:00 hour with the day's 23:00 hour (or the latest closed hour today). These are the last values we recorded in each hour, not Binance's official UTC daily close. A change is shown only when both anchor hours were recorded and nothing in between went unrecorded. The price-adjusted OI change removes the price move from the USD change.
Funding is the average of the rates quoted each hour, as an 8-hour equivalent. It is not the rate paid at settlement and is never summed. Basis is the perp mark against Binance spot for the same pair, averaged over the recorded hours.
Liquidations add up the forced orders seen during recorded hours. Binance's public stream shows at most one liquidation per symbol per second, so totals are a sampled lower bound. An hour we were not recording is left out rather than counted as zero.
Each day is recomputed from the data we still hold, so it is not a frozen snapshot. Recaps cover today and the 29 days before it.
