## Definition

Open interest (OI) counts every contract that has been opened but not yet closed. Rising OI while price rises usually means new buyers are entering (bullish momentum). Rising OI while price falls means new shorts piling in. Falling OI means positions are being closed. A sudden OI jump without a price move means leverage is building on both sides; how it resolves is not fixed in advance. We track the 1h / 4h / 24h OI delta for every perpetual on the pressure board.
