BTC: OKX Perpetual Open Interest
Shown as its 5–11 Feb 2024 sample; the latest readings and full history are included with Plus.
USD value of open BTC perpetual positions on OKX (all its BTC perpetuals together), one side of each position.
Why use it. A single venue's open interest with a longer history than our cross-venue charts, which start when our own collection began in October 2026: rising open interest means leverage entering the market, falling open interest positions closing. How to read it. Read the changes alongside price: price up with open interest up suggests new leveraged positions; a sharp drop marks liquidations or mass closing. One venue only, so compare its trend, not its level, with the cross-venue charts.
Calculation. Each period takes every OKX BTC perpetual's open interest at the period's close, in USD as OKX reports it, and sums them. Before our own collection of OKX began, the values are OKX's published figures: daily as far back as OKX serves them, and hourly for the latest 60 days it serves; from then on they are our own minute-by-minute collection of the same figure. Source: the public open-interest history OKX publishes for all its BTC perpetuals, read once by us on 7 November 2026: daily figures from 4 February 2024 and hourly figures for the latest 60 days (each contract from its listing if later). It is joined to our own collection of OKX's public futures data from 14 October 2026. OKX alone: other venues are not included, nor contracts OKX no longer lists.
