QuantorityOpen interest, explained
Open interest (OI) is the total USD value of outstanding perpetual-futures contracts for a coin. Unlike trading volume — which counts every trade — open interest counts positions that are still open. It is the cleanest measure of how much leverage is committed to a market right now.
Open interest vs volume
Volume can spike on a single frantic hour and mean little for positioning. Open interest only rises when new contracts are created (new longs and shorts entering) and falls when positions are closed or liquidated. Rising OI means fresh leverage is entering; falling OI means it is leaving.
Reading 24h and 7d change
A jump in OI is most informative read alongside price and funding. Rising OI with rising price and positive funding suggests new longs are leading; rising OI with falling price and negative funding suggests new shorts. See where leverage is building fastest on the OI gainers page, or where it is unwinding on OI losers.
How we aggregate it
Quantority sums USD-denominated open interest across Binance, Bybit, OKX and Bitget for each normalized symbol, so the figure reflects the whole cross-exchange market. Check any coin's open-interest page or the exact formula on the methodology. Nothing here is financial advice.
