Donna,
In this case I put all of them on at the same time with a neutral view of XLE. I have others where I started with 2 or 3 calendars and added additional calendar(s) in the direction the stock moved. I have more calendars in the XLE position partially because of the 1 point strikes and 6 is the most I would have active at one time. Other positions have a max of 5, 4, or 3. I look at the risk graphs and they will tell me when it doesn't help the position to add an additional calendar.
