All Cboe systems are operating normally. 

Please be advised that due to the approaching limit down state on the E-mini S&P futures, Cboe Options may per Cboe Rule 5.20 delay the opening of the GTH trading session for all SPX and VIX options should a limit state persist prior to the normal opening time for the GTH session.  If Cboe should make the decision to delay the opening for SPX and VIX options, notification will be sent, and Cboe will periodically re-evaluate the state of fair and orderly markets.  Should the E-mini S&P 500 futures exit the limit state, Cboe expects to open trading of SPX and VIX options approximately 10 minutes after that time.  Additional updates will continue to be distributed and added to the Options Systems Status page as necessary.

While SPX options are in queuing, the VIX index will not update but will start updating again approximately 15 minutes after the SPX options opening.

Please contact Cboe Trade Desk with any questions.
