5m bar 07:25–07:30 UTC

Free, from Aperiodic's own data. The hatched end of each chart marks the 15 minutes left out.

5m bars, 15 minutes behind. The newest runs 07:25–07:30 UTC; the next lands around 07:50 UTC, and the line under this bar fills until it does. Bars are labelled by their open and keyed on capture time: when Aperiodic received each trade, quote and update.

Every metric moves every 15 seconds, just as delayed, each a rolling window over the last 5 minutes, not a 15-second bar; funding, open interest and basis every minute, the finest they are measured at. The day's medians and means roll on with the 5m bars.

1626 perpetuals on Binance, OKX and Hyperliquid.

5m bars received in the last 24h: Binance 92.4% (171 with gaps) · OKX 81.1% (238 with gaps) · Hyperliquid 75.3% (159 with gaps).
