IT – INET Nordic – Reminder: Enhancement to the Market Maker Order (54/17)
As communicated earlier in 47/17, following requests from market participants, Nasdaq Nordic has decided to implement a set of enhancements to the current Market Maker Order (MMO). Testing of the enhanced functionality will be possible from September 25, 2017.
The MMO functionality is specifically designed to protect Market Makers (MM) in Warrants and Certificates. Whenever a match is about to take place with a MMO, matching is paused for 600 milliseconds (0.6 seconds), giving the MMs a possibility to update the MMO before matching continues.
The MMO functionality will now be further enhanced in a way that the order book will also be paused if the MM is not present on both sides of the order book (two-sided spread), or in the case the spread is too wide as defined in the INET Nordic Market Model. If the pause lasts for more than 10 minutes the order book will move into an automatic trading halt, and later flushed and released manually by Trading Surveillance.
During the pause, full order management applies, however matching will not take place.
The aim of the enhancements is to further improve the possibilities for effective and safe Issuer Market Making, while ensuring that retail clients are not executing at erroneous prices when the MM is not present in the order book.
Protocol specifications
There are no changes to protocol specifications. INET protocol specifications are available at Nasdaq Nordic Technical Information web site.
ITCH and GCF-TIP include information on MMOs in the order book. If an order book configured for MMOs is in continuous trading, without MMOs on both sides, the order book will be paused, hence there is no explicit flag indicating a pause in matching.
Legal and Market ModelThe INET Nordic Market Model will be updated, effective as of October 23, 2017 and changes will be available before the effective date.
The implementation of the changes is subject to discussions with regulators.
