What is an Option Chain?
  • An option chain, also known as an option matrix, is a listing of all available option contracts, both puts and calls, for a given security.
  • It shows all puts, calls, strike ltp, and pricing information for a single underlying asset within a given maturity period.

How is it Useful?
  • The option chain matrix is most useful for the next trading day.
  • Trading volume, or the number of contracts that change hands in a given day, indicates how much liquidity there might be for any given option.
  • Open interest measures the total number of options outstanding on each strike and maturity, allowing you to gauge the scale of market commitment.
