Please be advised that Cboe EDGX Options has identified a software defect that allowed for the generation of duplicate complex symbol ids for the same complex instrument. Cboe has determined that the source of the duplicate ids today is the result of activity from a single customer port and is working with the customer on a resolution to prevent further duplicate ids from being created for the remainder of the day. A software patch will be implemented this evening to permanently address this issue and effective tomorrow any duplicate complex ids that were generated will be removed from the system. In addition, all complex GTC orders are expected to persist to the next trading day without issue. The other Cboe Options Exchanges are not susceptible to this issue and are operating normally. Please contact the Cboe Trade Desk with any questions.

Please be advised that Cboe is currently investigating system issues on the Cboe EDGX Options Exchange where customers have reported duplicate complex symbol ids for the same complex instrument. Cboe will advise when more information is known.

Cboe C1 Options Exchange Issue Resolved

Please be advised that floor routing for the Cboe Options ("C1") Exchange has been re-enabled and all PAR workstations are now accepting orders.  

All Cboe systems are operating normally.

Cboe C1 Options Exchange System Status
March 15, 2021 09:31:31

Please be advised that due to a system issue currently under investigation, floor routing has been disabled for the Cboe Options ("C1") Exchange. 

Routing to PAR workstations on the C1 Trading Floor is currently unavailable. Orders routed to PAR will be rejected back to the user.  All orders currently residing on PAR will be cancelled.
Cboe will provide updates once further information is available.
All non-PAR C1 systems and all other Cboe systems are operating normally.

Cboe has determined that it is approaching its maximum sequence value on the Cboe Options Multicast PITCH proprietary market data feed for matching unit 34 supporting SPXW and anticipates rolling over sequence numbers.

As indicated in a previous notice, when the message sequence number reaches the maximum value of 4,294,967,295 the message sequence number will rollover, and the next sequence will be one (1).
Cboe has included examples in the Cboe US Equities/Options Multicast PITCH Specification that illustrate this behavior in the context of a SPIN or GRP request that might occur around the time when the sequence rolls over.
No further notifications will be sent by Cboe regarding sequences rollovers, as these events are described in all relevant market data specifications and are expected to be handled by customers as part of normal operations.
