Open InterestOpen interest refers to the number of outstanding contracts that remain open. For example, if a position was taken in a contract, and at the expiry of that contract, instead of closing out the position, the trader decided to roll the contract over (ie open a similar position in the next expiry month), their open interest in that contract would continue. If however the trader decided to close out their position, the open interest for that contract would decrease.
