DEFINITION of 'Option Chain'
A form of quoting options prices through a list of all of the options for a given security.

BREAKING DOWN 'Option Chain'
Option chains are probably the easiest form of presentation for most retail investors to understand when observing option quotes. Much like a matrix, traders can simply find an options premium by following the corresponding maturity dates and strike prices. Additionally, bid-ask quotes or simply mid quotes can be displayed within an option chain, depending on the presentation of the data.
