What is a calendar put spread?

NeutralLimited ProfitLimited Loss

A neutral to mildly bearish/bullish strategy using two puts of the same strike, but different expiration dates. If the stock is near strike A when the earlier call expires, you will be able to close it for a profit.

Use an at-the-money strike to make this strategy neutral, or a slightly out-of-the-money or in-the-money strike to give a bullish or bearish bias.
