yeah, you've got it. If AAPL runs down below $105 you have to start thinking about exiting the trade if you are within a few days of expiry, because the itm short puts could be assigned. If you are short options, you're obligated to sell them, regardless of whether they are in a spread or not. But I will go into assignment risk later. I'm looking for a good example to show you how I trade calendar spreads around ER's.....
