Read open interest in its original units
Distinguish the count of open contracts from the source-reported BTC or ETH quantity, then preserve the exact result with its venue and clocks.
1. Select the contract and its source
The COIN-M overview concerns Binance BTCUSD_PERP and ETHUSD_PERP perpetual contracts. These contracts are quoted in USD and collateralized in BTC or ETH. They are separate from spot assets and from Binance USDⓈ-M USDT contracts in the funding overview. The venue and contract family are part of the meaning of each value.
Choose BTC, ETH or both, then apply the prepared selection explicitly. Before applying it, the admitted result remains the previous one. The available history is the range actually captured from the source; it is not the full history of the instrument or the total across all exchanges.
2. Keep contract counts separate from coin quantities
The main value is the original sumOpenInterest contract count. The table also preserves sumOpenInterestValue in the contract’s base asset: BTC for BTCUSD and ETH for ETHUSD. These are two source-reported quantities at the same source point, with different units. A count of contracts is not a number of Bitcoin, and BTC and ETH quantities cannot be added together as one coin balance.
The chart displays contract counts. Its lines retain their own contract labels and do not imply equal dollar exposure. Current contract metadata alone does not prove the multiplier effective at every historical point. This workflow therefore leaves historical USD notional unavailable instead of manufacturing it from an unverified historical conversion.
3. Interpret the reported time and limits
The source timestamp identifies the reported period end for a daily open-interest observation. It does not mean the day’s traded volume, an average over the whole day or a publication clock. Datisto’s capture clock separately records when the complete source evidence became available. Open Passport to inspect the exact value, original coin quantity and recorded source identity.
A larger count says that more contracts remain open under the source’s definition. It does not by itself identify new long demand, new short demand, leverage, a liquidation level or a future price direction. Unknown or unavailable values remain distinct from a genuine reported zero. Later refreshes may add observations; the stored capture is not a guarantee of realtime availability.
This is a guide to Datisto. Private features require sign-in and access to your own data. Personal models use your assumptions; availability and permitted use of source data are checked with the particular result. This is not investment advice.
