Each line compares a contract's last hour with its own last 24 hours: its volume against a usual hour, its spread against the day's median, its top-of-book depth and slippage against the day's average, and the hour's move against its usual hourly swing. An hour, not one 5-minute bar: what shows has lasted. Two are fixed bars instead: takers on one side 1.5:1 or more over the hour, and open interest moving 3% or more in an hour. There is no time-of-day profile, so the US open and funding times show up too. Contracts trading under $10M a day are left out. It describes what happened, not what comes next.

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 23:10–23:15 UTC; the next lands around 23:35 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.

This page reads each perp’s last hour against its own day from the 5m bars, so it changes once a bar, when the next one lands.

1628 perpetuals on Binance, OKX and Hyperliquid.

5m bars received in the last 24h: Binance 93.8% (166 with gaps) · OKX 81.1% (251 with gaps) · Hyperliquid 80.9% (143 with gaps).

How to read it

The perps whose last hour looks least like their own last 24 hours, as they appear.

Each line compares a contract's last hour with its own last 24 hours: its volume against a usual hour, its spread against the day's median, its top-of-book depth and slippage against the day's average, and the hour's move against its usual hourly swing. An hour, not one 5-minute bar: what shows has lasted. Two are fixed bars instead: takers on one side 1.5:1 or more over the hour, and open interest moving 3% or more in an hour. There is no time-of-day profile, so the US open and funding times show up too. Contracts trading under $10M a day are left out. It describes what happened, not what comes next.

At the last update: Unusual activity across every perp: XYZ:GOLD on Hyperliquid: takers sold 99× what they bought in the last hour; LYN on Binance: top-of-book depth at 3% of its day's average over the last hour; XYZ:MU on Hyperliquid: takers sold 5.6× what they bought in the last hour.
