Please be advised that due to a system issue, FLEX SPX AIM orders are currently being rejected by the Cboe Options ("C1" or "the Exchange") system. To address this issue, SPX AIM will be systematically enabled on C1 for the remainder of today, Monday June 29, 2020. However, the Exchange is not permitting AIM for SPX, and TPHs are advised not to submit non-FLEX SPX AIM orders. While such orders will not be rejected, the submission of such orders may be a regulatory rule violation and any resulting trades may be busted.

At this time, the final indicative prices for all SPXW series have been posted to the Cboe Final Indicative Prices website, and the complete set of prices has been forwarded to the OCC.

The underlying software defect will be resolved by a software patch to be deployed to all Cboe options exchange platforms on Wednesday, March 11, 2020.

Please be advised that as of approximately 12:34 ET, Cboe has resolved all issues with various options classes remaining in a halted state the Cboe BZX, C1, C2 and EDGX Options Exchange platforms.

While all Cboe systems are currently operating normally, please be advised that Cboe C1 Options Exchange surpassed 95% of the maximum allowable sequenced messages on its Multicast PITCH proprietary market data feeds for Matching Unit 34 supporting SPXW at approximately 2:57 pm CT today due to current market activity. Should C1 exceed this value, additional notification will be provided to market participants. Based on current trading activity, the potential exists to exceed this allowable number for matching unit 34 supporting SPXW during the course of today’s trading at a non-predetermined time.

In the event C1 exceeds the maximum allowed sequence messages on the Multicast PITCH feed for Matching Unit 34, SPXW market data will remain available and unaffected via the proprietary Multicast TOP feed, complex order book market data feed, and COA market data feed, as well as via PAR market data systems and the floor data walls. In addition, SPXW market data will remain available to market participants via OPRA. However, the C1 proprietary Multicast PITCH market data feed for SPXW will become unavailable for the remainder of the day.

As indicated in a previous notice, Cboe has identified a limitation in the number of available sequenced messages on the C1 Multicast PITCH proprietary market data feed. This is a result of all proprietary Cboe market data feeds supporting a four (4) byte decimal sequence number which has a maximum value of 4,294,967,295. This situation continues to be monitored closely while a long term sequence rollover solution, detailed in a previous notice, is being implemented.

Note that this issue only impacts the proprietary Multicast PITCH market data feed for SPXW; all other systems not related to SPXW Multicast PITCH market data, including all systems supporting SPX, continue to operate normally. Note also that Cboe does not intend to close trading early in SPXW or any other classes today, nor are there plans to cease floor trading for SPXW or any other class.

As indicated in a previous system status notice, Cboe Options Exchange ("C1") identified a limitation in the number of available sequenced messages on proprietary market data feeds. This is a result of all proprietary Cboe market data feeds supporting a four (4) byte decimal sequence number which has a maximum value of 4,294,967,295.

Effective this morning, March 2, 2020, a patch has been deployed to allow for the proprietary Multicast TOP feed, PAR market data systems, and the floor data wall systems to remain available in the event C1 exceeds the current maximum allowed sequenced message on any PITCH market data unit.

However, the risk remains that under extreme traffic conditions the Cboe proprietary Multicast PITCH data feed may become inaccessible for one or more market data units. This situation continues to be monitored closely while a long term sequence rollover solution, detailed below, is being implemented. Should Cboe determine that it is approaching the maximum number of available Multicast PITCH message sequenced numbers for any matching unit, notification will be sent at 70%, 80%, 90%, and 95% of that maximum.

In recognition of the need for a long term solution on the Multicast PITCH feed, Cboe will be working diligently to implement a sequence rollover solution. On the Cboe Multicast PITCH feed, matching unit sequence numbers start at one (1) at the beginning of the day and are incremented by one (1) for every sequenced message within a particular symbol unit. As of a soon to be announced effective date, when the message sequence number reaches the maximum value of 4,294,967,295, the message sequence number will rollover back to one (1). Cboe will provide follow up notification regarding member testing opportunities and production release date for this solution. Please refer to the Cboe Options Multicast PITCH Specification for additional details.

As indicated in a previous system status notice, Cboe Options Exchange ("C1") identified a limitation in the number of available sequenced messages on the Multicast PITCH and TOP proprietary market data feeds. This is a result of all proprietary Cboe market data feeds supporting a four (4) byte decimal sequence number which has a maximum value of 4,294,967,295. The result of this limitation is the risk of Cboe proprietary PITCH/TOP data feeds becoming inaccessible under extreme traffic conditions for both electronic and open outcry trading systems.

Effective Monday, March 2, 2020 a patch will be deployed to allow for the proprietary Multicast TOP feed, PAR, and floor data wall systems to remain available in the event C1 exceeds the current maximum allowed sequence message on any PITCH market data unit.

The risk of exceeding the maximum allowed sequence messages on the Multicast PITCH feed will remain on Monday and will continue to be monitored closely while a long term sequence rollover solution is implemented (see below for more details).

In recognition of the need for a long term solution on the Multicast PITCH feed, Cboe will be working diligently to implement a sequence rollover solution.

As of a soon to be announced effective date, when the message sequence number reaches the maximum value of 4,294,967,295, the message sequence number will then rollover back to one (1). Please refer to the Options Multicast PITCH Specification for additional details.

Please be advised as of the 3:00 pm CT market close, Cboe C1 Options Exchange had reached 98% of the maximum allowable sequenced messages on its Multicast PITCH proprietary market data feeds for Matching Unit 34 supporting SPXW.

Should this limit be exceeded during post market trading, Cboe is prepared to take actions to continue trading in SPXW as indicated in this previous notice. Subsequent notification will also be sent.

In addition, should this limit be exceeded the C1 proprietary TOP and PITCH market data feeds for the SPXW simple order book will become unavailable for the remainder of the day. SPXW simple order book PITCH/TOP market data will remain available to market participants via OPRA; SPXW proprietary complex order book market data and COA market data will also remain available and unaffected.

Note that this issue only impacts SPXW market data; all other systems not related to SPXW market data, including all systems supporting SPX, continue to operate normally. Note also that Cboe does not intend to close trading early in SPXW or any other classes today, nor are there plans to cease floor trading for SPXW or any other class.

As indicated in a previous notice, Cboe has identified a limitation in the number of available sequenced messages on the C1 Multicast PITCH proprietary market data feeds for Matching Unit 34 supporting SPXW. This is a result of all proprietary Cboe market data feeds supporting a four (4) byte decimal sequence number which has a maximum value of 4,294,967,295.

Please contact the Cboe Trade Desk or your director of sales with any questions.

As indicated in a previous notice, Cboe Options Exchange (“C1”) has identified a limitation in the number of available sequenced messages on the Multicast PITCH proprietary market data feeds for Matching Unit 34 supporting SPXW. This is a result of all proprietary Cboe market data feeds supporting a four (4) byte decimal sequence number which has a maximum value of 4,294,967,295.

Due to current market activity, as of approximately 12:45 pm CT Cboe C1 Options Exchange surpassed 80% of this value and the potential exists to exceed this allowable number during today’s trading at a non-predetermined time. Should C1 exceed 90% of this value, notification will again be provided to market participants. Note that this issue only impacts SPXW market data; all other systems not related to SPXW market data, including all systems supporting SPX, will continue to operate normally. Note also that Cboe does not intend to close trading early in SPXW or any other classes today, nor are there plans to cease floor trading for SPXW or any other class.

In the event C1 exceeds the maximum allowed sequence messages on the Multicast PITCH feed for Matching Unit 34 supporting SPXW, electronic and open outcry trading will remain available for SPXW as well as for all other classes. SPXW simple order book market data will remain available to all market participants via OPRA, via the data walls which will be sourced from OPRA, and via OPRA data on PULSe, but market data for SPXW will be unavailable for the remainder of the day on PAR or via any other proprietary or third-party systems that rely on Cboe proprietary PITCH/TOP data. SPXW proprietary complex order book PITCH/TOP market data and COA market data will remain available and unaffected.

Should SPXW market data become unavailable via PAR, Cboe will send a market data value message to the PAR terminals which will appear as bid/ask prices of 0.01 – 9999.9999, 9999 x 9999. This message will clear any stale data present after SPXW market data becomes unavailable, thereby allowing continued use of the Trade with All, Sweep, Book, and Auction functionality. Note however that Trade with Book functionality will not be available. In addition, the PAR calculator will not provide accurate leg prices and should not be used for this purpose; all SPXW leg prices should be entered manually. PAR brokers are also requested to use the PAR “SWEEP” button to clear any electronic interest that may be resting in the book in the event an open outcry trade might occur at or outside the BBO viewable via OPRA data on PULSe or on the data walls and other market data sources.

Please refer to forthcoming Cboe Regulatory Circulars for more information.

Per the Post Mortem update distributed on Wednesday, January 8, 2020, effective for today's trading Cboe has deployed a software patch to resolve the issue where the Cboe Clearing Editor could improperly reduce trading volume on OPRA.  A list of trades where volume was incorrectly removed is available here. This list also includes 58 trades which under specific edge case conditions were not originally reported to the Tape. Cboe is currently addressing this issue and will provide an updated notice with a list of any additional such trades should they occur. In all cases, each row in the list of trades represents volume that should be added back to the Tape for an accurate historical record.

Post Mortem: Cboe Options Exchange OPRA Trade Reporting Issue

SCI System(s) Affected: OPRA Printer (Trade Reporter)

Incident Description: Compliance
Please be advised that Cboe Options Exchange has identified a software defect where the Cboe Clearing Editor could improperly reduce trading volume counts on OPRA. This issue had no impact related to clearing of any trades. This issue was introduced on October 7, 2019 and unnecessarily reduced the contract volumes on less than 300 trades since that date.

Members Affected: OPRA recipients.

Corrective Action: This defect will be resolved by a software patch to be deployed this Friday, January 10, 2020 at which time Cboe will also issue an updated notice with a link to a full list of trades where volume was incorrectly removed from the tape.
