One of the ways to deploy Calendars is right before earnings to capitalize on the volatility expansion that will almost always happen nearer to earnings day.
Calendar Spread Earnings Setup involves selling near month before earnings and buying far month after earnings. Otherwise, we follow many of Durational Calendar Spread rules. IVR should be low and Option Volatility between the 2 months which we are selling and buying should not be too wide. Looking at 20%-30% profit.
