About the CAT open interest
What is CAT open interest?
Open interest (OI) is the total value of all open CAT perpetual futures positions, in USD. Every open contract has a long and a short side, so OI counts one side only. It rises when new positions open and falls when positions close or are liquidated.
How to read OI with price
OI up, price up: new positions opening as price rises, usually fresh longs. OI up, price down: fresh shorts. OI down, price up: shorts closing (a short squeeze if fast). OI down, price down: longs exiting or being liquidated. Large OI changes in a few hours show where leverage is building or unwinding in CAT.
Where the numbers come from
The current CAT OI total includes public API data from Aster, Binance, Bitget, Bybit and KuCoin. Current coverage: 5 exchanges (MEXC excluded) · see coverage. Excluded venues remain visible per market but contribute neither to the combined total nor to row shares. Markets with missing or stale OI also have no share. OI is converted to USD at the mark price, so part of an OI change can come from the price move itself. Changes compare the current value with 5-minute snapshots the server has recorded since it last started.
Is this aggregated CAT open interest?
