- Look Up an Option Symbol

Overview

An option chain is a list of all current call symbols and put symbols available for an underlying security based on specified filtering criteria. Detail for each symbol includes the expiration date of the option contract, strike price, last price, change in price, bid price, ask price, volume, and open interest.

Option Chain assists you in completing the Symbol/CUSIP field on several trade-related windows that require an option symbol.
