I'm not sure, but if you wait until the last hour on Thursday and your short strike is 5 to 10 points away, you might be able to close it for a nickel or a dime even if you just have to buy back the short strike and forget trying to sell the long. I know I have done this in the past, but I don't have detailed records on where the SPX was relative to my short strike. Still if I was far away I would have let it expire, I think. Therefore, I'm thinking the SPX must have been close enough to cause me concern.
I think that this is an important point and it would be nice to see if anyone has any real-world experience. I'm talking about getting out in the last hour or so on Thursday expiration. I'm pretty sure I have still seen reasonably large credits on some of my past OTM credit spreads on Thursday morning only to have these rapidly disappear by the last hour (SPX was reasonably flat so it didn't appear to be the result of a big move on the SPX).
I just don't remember, didn't carefully document it and haven't had it happen recently. But I would like to know if what I think happened is reasonably correct.
