Yes, you are liable for changes if you dont close out position day before expiration. the settlement value is calculated a little differently from the normal VIX formula using interpolation (because on settlement day there is exactly 30 days so no need to interpolate between two expirations)When does the December contract expire? At what time? If it is past expiration time but not yet settled (and thus not tradable even though it shows in my account) am I liable for any changes?
IB does the same thing, the positions show all day and disappear the next day. Check your margin, it should change immediately after settlementNot sure if that boilerplate answers my question about why the contract is still listed in my account at 12:30 PM after expiration. Maybe that's a Schwab issue.

Although it is your prerogative why do you feel forced to trade something you don't understand very well.I guess today this should be a positive change in my favor, unless the sky falls.
