Open interest is the total number of outstanding derivative contracts, such as options or futures that have not been settled for an asset. The total open interest does not count, and total every buy and sell contract. Instead, open interest provides a more accurate picture of the options trading activity, and whether money flows into the futures and options market are increasing or decreasing.

Open interest, we must first explore how options and futures contracts are created. If an options contract exists, it must have had a buyer. For every buyer, there must be a seller since you cannot buy something that is not available for sale.

Open interest is commonly associated with the futures and options markets, where the number of existing contracts changes from day to day. These markets differ from the stock market, where the outstanding shares of a company’s stock remain constant once a stock issuance has been completed.
