In Derivatives, When Would a Contract Use a “Request and Response” Model?

A derivatives contract would use this model for settlement based on a specific, non-continuous event. Examples include an options contract settling at a precise expiration time or a binary options contract based on a discrete event outcome, like a company reaching a revenue milestone.

It is used when the final price or outcome is only needed once, at a pre-determined point in the future.
