Futures & options
Also called: OI, Open interest
Open interest (OI) is the number of futures or options contracts that are still open — traded but not yet closed or settled. It rises when new positions are created and falls when existing ones are closed.
A new buyer and a new seller trade one Nifty call contract: OI rises by one. If later both close those positions with each other, OI falls by one. If one side opens and the other closes, OI is unchanged.
Volume counts every trade in a session; open interest is the level of positions outstanding at the end of it.

No. Open interest describes one aspect of a company, a price or a contract, and it is best read alongside other numbers and the business itself. Jivani Markets is a research and education platform; it does not give buy, sell or hold recommendations.
