In TWS, the closing quote for ES and NQ options (and perhaps other GLOBEX contracts) uses the settlement price from two days prior instead of the previous day's settlement price. This results in incorrect figures in the "change" column when compared to the previous day. Perhaps the issue is trading resumes 15 minutes after each day's close so the final settlement price isn't posted by the CME before the next day's trading begins. (This doesn't excuse having it wrong on Monday morning, though.) It's not a super big deal, because I obviously know the price where my trades are executed. Has anyone else discussed this or brought it to IB's attention? I sent it in about a week ago by e-mail and oher than a "bot" acknowledgement, I've received no reply or update. How long does IB usually take to correct something like this (assuming they will)?
