Calendar Spread


In finance, a calendar spread is a spread trade involving the simultaneous purchase of futures or options expiring on a particular date and the sale of the same instrument expiring on another date. The legs of the spread vary only in expiration date; they are based on the same underlying market and strike price.

What is a ‘Calendar Spread’

A calendar spread is an options or futures spread established by simultaneously entering a long and short position on the same underlying asset but with different delivery months. Sometimes referred to as an interdelivery, intramarket, time or horizontal spread.

Explaining ‘Calendar Spread’

An example of a calendar spread would be going long on a crude oil futures contract with delivery next month and going short on a crude oil futures contract whose delivery is in six months.
