SCI System(s) Affected: Matching Engine, OPRA and Proprietary Feed Quoting
Incident Description: Systems Compliance
Due to a software error related to implementation of new price sliding logic introduced within the BOE quoting interface today, symbols that are only allowed to be quoted in nickel increments were in some cases allowed to be quoted in penny increments via the quoting interface.
Members Affected: BZX Options Members utilizing the quoting interface that selected to use new price sliding functionality.
Corrective Action: At 9:59:47 AM ET, the new price sliding functionality was disabled for the remainder of the day to ensure new quotes would no longer be displayed in penny increments for securities that are to be displayed in nickel increments.  A software patch will be deployed for tomorrow (7/9/19) to correct the software defect that resulted in this behavior and the new price sliding logic will be re-enabled.

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.
