BTC: Perpetual CVD Heatmap, Scaled by Open Interest (All Assets)
Shown as its 2–31 Oct 2026 sample; the latest readings and full history are included with Plus.
Every coin's perpetual taker buying minus taker selling in each period, as a percentage of its open interest, one row per coin.
Why use it. Shows which coins aggressive buyers or sellers are pressing; scaling by open interest makes small and large coins comparable. 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 net taker buying, red cells net taker selling, on a two-sided scale. The summary value is the same for every coin together.
Calculation. Per coin: 100 x (perpetual taker buy volume - taker sell volume) / closing perpetual open interest, both in USD. 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.
