UPDATE: Post Mortem - Cboe Options Exchange OPRA Trade Reporting Issues

November 04, 2019 15:19:28

Per the Post Mortem update distributed on Friday, November 1, 2019, Cboe has generated a list of trades impacted by each of the three previously defined software defects relating to OPRA printing on Cboe Options Exchange.

The first defect resulted in certain floor trades, including some that were edited post trade, to be reported as REGULAR trades rather than LATE trades to OPRA. This issue was introduced on October 7. The list of trades reported as REGULAR rather than LATE can be found here.

The second defect allowed floor trades that were not reported to the Exchange within 60 seconds of execution, but were reported within 90 seconds to be designated as late. Cboe Rule 6.1 allows for trades reported within 90 seconds to be classified as regular trades. This issue was introduced on October 24. The list of trades reported as LATE rather than REGULAR can be found here.

The third defect allowed for certain post trade edited floor trades to be duplicated on OPRA as a result of the original trade not being correctly reversed. This issue was introduced on October 28. The list of original trades that were not correctly reversed which was also made available on Friday, November 1 can be found here.

Post Mortem: Cboe Options Exchange Floor Disruption

October 28, 2019 17:11:08

Post Mortem: Cboe Options Exchange Floor Disruption
SCI System(s) Affected: PAR, Matching Engines

Incident Description: Disruption

At 9:30AM ET, the vendor processing equity legs of complex orders for Cboe Options Exchange ("C1") experienced a technical issue. In response, as part of its normal procedures the Cboe Trade Desk issued a command to redirect processing of complex orders with equity legs to the trading floor (PAR system).

Due to a software defect, this action resulted in the PAR order processing systems becoming overwhelmed with order traffic. This ultimately required disabling routing to the trading floor at 10:05:22 AM ET. All orders remaining on PAR were cancelled, and after extensive troubleshooting the decision was made to restart the PAR system at 12:30 PM ET.

The intra-day PAR system restart resolved most issues with processing and representing orders on the floor. However, sporadic issues resulting from delayed market data continued until 2:29 PM ET.

Members Affected: C1 floor brokers and TPHs routing orders to the floor.

Corrective Action: The underlying software defect has been identified and will be patched for tomorrow. Cboe will examine all issues identified during the troubleshooting and floor system restart process to ensure all items are fully addressed.

Post Mortem: Cboe C2 Options Exchange Systems Issue


SCI System(s) Affected: Matching Engine

Incident Description: Systems Disruption

Due to a suspected software error, a Matching Engine supporting option classes in the range IWM-JNJA crashed at 09:30:14 ET. The system immediately initiated the failover process to the secondary instance of the affected Matching Engine, which completed at 09:31:03 ET. Shortly thereafter, the Cboe Trade Desk began investigating an issue where certain options series on the Matching Engine were not transitioning to an open state. This was determined to be the result of a software defect within the failover process to the secondary Matching Engine instance and at 10:09:49 ET the Cboe Trade Desk manually forced open all classes on the Matching Engine, which caused all previously entered orders to be cancelled back to TPHs.
 
TPHs Affected: 13 firms
 
Corrective Action: A software patch will be deployed on Thursday, May 23rd to correct the software defect in the failover process. Investigation into the root cause of the problem that caused the initial Matching Engine crash is ongoing.

Post Mortem: EDGX Options BOE Issue


SCI System(s) Affected: BOE Order Handlers

Incident Description: Systems Disruption

As previously announced, support for BOE Bulk Order messages ended on March 29, 2019. Today, the underlying software code supporting Bulk Orders and all related fields was removed from the EDGX Options system. This resulted in login rejects for nine firms attempting to login but selecting to receive optional fields for the Bulk Order Acknowledgement return message type. Firms choosing to opt-in for other Bulk Order-related fields such as ClOrdIdBatch were able to login, but that field was omitted from return messages. This resulted in messages that were shorter than expected for one firm.

Members Affected: 10 firms

Corrective Action: Software code support for BOE Bulk Order related message types and fields was re-introduced to the EDGX Options system via an emergency software patch. BOE order handlers were restarted to allow affected firms to login. This was completed at 09:42:15 ET. One firm was logged in successfully but had issues handling shorter return BOE messages. This issue was also resolved as of 11:17:18 ET by restarting BOE order handlers for this firm which enabled them to receive messages of the expected size. The software patch to support BOE Bulk Order related message types and fields as they were prior to today will remain in place for tomorrows trading. No further impact to EDGX Options nor to any other Cboe exchange is anticipated.
