Definition of 'Binary Option'

A Binary Option is a type of option where the payoff is either:
  • Some fixed amount of some asset
  • OR
  • Nothing at all
Binary Options fall into two primary types:
  • Cash-or-Nothing binary option
  • Asset-or-Nothing binary option
Cash-or-Nothing binary option example
This type of option pays a fixed amount of cash if the option expires in-the-money. For example, if you bought a binary cash-or-nothing put option on IBM with a strike price of $200 with a binary payoff of $2,000 and at the maturity date IBM is trading at or under $200 then you will receive $2,000. Conversely if IBM is trading over $200 then you will receive nothing.
