Every number on this site comes from exchanges' public market-data APIs. This page lists each exchange we read, what we record from it, how complete that data is, and how far back history goes, generated from the live feed registry so it never goes stale.
8 of 8 exchanges are live right now, with 5,270 markets and $85.55B of perpetual open interest tracked. Liquidations are recorded completely on Bybit, Gate and HTX, which hold 18% of that open interest. Binance and Bitget only publish a sample of their liquidations, so totals that include them are a floor, not a full count.
USDT perps: open interest and funding polled over REST every 60s; KuCoin publishes no liquidation feed
Complete: the exchange publishes every liquidation and we store each one. Sampled: the exchange publishes only some (for example at most one per symbol per second), so totals are a floor. Open interest is valued at the current mark price and counted one side only.

History before this site began recording comes only from the exchanges' own public APIs, for the series where they offer it (such as funding rates); no third-party data is mixed in. Charts mark periods when the recorder was not running as gaps rather than zeros. How the estimated liquidation heatmap uses this data, and how accurate it is: liquidation heatmap methodology.
Data coverage FAQ
Which exchanges' liquidations are complete?
Bybit, Gate and HTX. Those exchanges publish every liquidation on their public stream, and this site stores each event. Every other exchange either samples its liquidation stream or has none, as the table shows.
Why do liquidation totals differ from other sites?
Some exchanges publish at most one liquidation per symbol per second (or only the largest), so anything built on their public stream undercounts, on this site and elsewhere. We label each exchange as complete or sampled rather than scale the numbers up with a guess.
How far back does the history go?
Hourly price, volume, open interest, funding and long/short history is kept forever from when recording started; finer resolutions are kept for the periods in the history table. Every liquidation event is kept.
Where does the data come from?
Each exchange's own public market-data API, plus the CFTC's public Commitments of Traders report. No paid data vendor, no scraping, and never CoinGlass.
