What is OI for option contracts, and how does it work?

Open interest is the total number of outstanding derivative contracts, such as options or futures that have not been settled for an asset. It is the number of options or futures contracts that are held by traders and investors in active positions. These positions have been opened, but have not been closed out, expired, or exercised. Open interest decreases when buyers (or holders) and sellers (or writers) of contracts close out more positions than were opened that day.
