BTC: Open Interest Change Heatmap (All Assets)
Shown as its 2–31 Oct 2026 sample; the latest readings and full history are included with Plus.
The change of every coin's perpetual open interest in each period, in percent, one row per coin.
Why use it. Shows where leverage is being added or cut across the market at a glance, and whether a move is broad or confined to a few coins. How to read it. Coins run down the side, largest open interest at the top, and time runs across; each cell is one coin in one period. Blue cells are open interest growing, red cells shrinking, on a two-sided scale. The summary value is the change of the coins' total.
Calculation. Per coin: (closing perpetual open interest / the previous period's - 1) x 100. Source: our own minute-by-minute collection of public futures data across every coin with perpetual futures that CryptoKeyhole covers, from Binance, Bybit, OKX, Deribit, Kraken, Bitfinex, Bitget, Gate, Hyperliquid, KuCoin, HTX, Crypto.com and Coinbase (open interest, funding, and the public liquidation feeds we collect), and our own USD price indexes. Each coin counts with the same values its own charts show. The series start on 24 October 2026, the first day our collection held every coin's open interest, funding, liquidations and price; a coin added later joins on the day its collection begins. A period appears once nine in ten of the coins have published it, so the open hour can trail by a few minutes. Venues we do not collect are not included, so totals understate the whole market.
