Sorry for being a bit of a wise ass. . .couldn't help it. The buyer (or seller) of an options contract can buy or sell the same contracts at any time prior to options expiration. Contracts are created with transactions "to open". Whoever bought (or sold) those contracts added to open interest during any "opening" transaction. If they subsequently sold "to close", their number of contracts is then subtracted from open interest. New contracts created with an opening transaction do not need to remain in existence until expiration or exercise, etc. This is it in simplest terms. hope that helps.
