CASHCAT perps on OKX and Hyperliquid, from Aperiodic's own 5-minute bars, free and 15 minutes behind. Every perp, A–Z →

Every number here is 15 minutes behind

5m bar 23:15–23:20 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 23:15–23:20 UTC; the next lands around 23:40 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.

1659 perpetuals on Binance, OKX and Hyperliquid.

5m bars received in the last 24h: OKX 99.7% · Hyperliquid 99.3%.
