MIAX Exchange Group: Delaying Mandatory Upgrade to Consolidated Audit Trail (CAT) Timestamp Supporting Interface Version

As previously announced in the November 20, 2019 and February 13, 2020 Alerts, the MIAX Exchange Group published updated Interface Specifications to support the reporting of the Market Maker Firm Timestamp to CAT via the Exchanges.  Due to disruptions as a result of COVID-19, the mandatory implementation is being delayed.  An updated Alert will be published once new dates are available.

The new protocol version will become mandatory and old messages will be rejected in the new protocol.  These changes require a mandatory certification prior to being upgraded in the production environments.  Certification is currently available in the Firm Test Bed (FTB2) environments.

Please contact MIAX Trading Operations at TradingOperations@miaxglobal.com or (609) 897-7302 to discuss any specific issues and to arrange interface testing.
