Sell To Close A phrase used by many brokerages on the street to represent the closing of a long position in option transactions. Investopedia Says: An investor can sell to close either (or a combination of) puts or calls and thus will be relinquishing ownership of the option(s). The distinguishing factor of a sell to close is that the option position must have been held long in the account during the transaction.
