Open interest is distinct from volume: volume counts how many contracts are traded in a session, while open interest counts how many remain open at the end of the day. Rising OLN options open interest alongside rising volume suggests new positions are being built, while falling open interest signals positions are being closed. Heavy open interest at specific strikes often acts as a magnet near expiration and can hint at where dealers and large traders expect Olin Corp to settle.
