Quote from jimmyjazz:
Understood. My question remains, would a broker typically force me to take delivery of shares on an ITM short put that is suddenly exercised EARLY if I also hold an ITM short put at a different strike? Or would a broker typically just net out the trade by simultaneously exercising my long put (with an additional cash transaction)?
Similar question on early exercise of short ITM calls.
You would get the shares, your broker wouldn't early exercise a long put for you. There's no auto early exercise like there is an auto exercise at expiration. If it was optimal to exercise early, then you should have done so on your long itm put (I'm assuming you meant you held a long itm put at another strike, even though you wrote short). That's the point I was trying to make in my first post - early exercise risk isn't only a problem for the shorts.
Same thing for calls.
It sounds like your questions have mainly been about when to exercise early, and procedures for assignment at expiration. There's a lot of different scenarios that can come up, so it's important to look into these so you know how it'll affect your account (there are also margin considerations).
