What this data is
Open interest
Open interest is the number of contracts that exist right now: every long has a matching short, and the count only changes when new positions open or old ones close. It's the cleanest measure of how much leverage sits in a market. Volume tells you how much traded; open interest tells you how much is still on the table.
Rising open interest with rising price means new longs are driving the move. Rising open interest with falling price means new shorts are. When price moves while open interest falls, positions are being closed, which is what a squeeze looks like from the inside.
The table shows each asset's open interest in dollars on Binance, Bybit and OKX, and the total across the three. The hourly Binance series behind the 24-hour change goes back to January 2021 and comes with the JSON API and the CSV.

How to read it
- Read open interest together with price. The four combinations (price up or down, open interest up or down) tell you whether a move is being built or unwound.
- A sharp drop in open interest inside an hour usually means forced closes; the liquidation totals for the same hour show how much.
- Open interest in dollars moves with price even when no contract opens or closes, so compare the dollar change with the price change before reading it as new leverage.
