Nasdaq GEMX unveils re-platform plans
Nasdaq GEMX will undergo a re-platforming with the goal to harmonize exchange technology positioning participants for future growth and success.
Updates will be made to the GEMX Market Data feeds under the new platform. While each of the current market data offerings will continue, there will be some changes to both the naming of these and the protocols.
The GEMX Top Quote Feed will be renamed to the GEMX Top of Market Feed. It will remain a book-based feed designed to provide the Best Bid and Offer and last sale information. The feed will contain updated message formats that are harmonized with BX Options. An optional Glimpse service will also be made available for the Top of Market Feed for recovery.
The GEMX Depth of Market Feed will be improved to include full depth with order-by-order messages. It is important to note that firms receiving this product will now need to recreate the order book on their own. The new but familiar Depth of Market feed will share similar components to the recently updated BX Depth of Market Feed. An optional Glimpse service will also be made available for the Depth of Market Feed.
The GEMX Order Feed will continue to provide a snapshot of each order that rests on the order book along with auction notifications but will take on updated message formats.
The GEMX Trade Feed will continue to provide last trade information along with opening price, cumulative volume, high and low prices for the day as well as administrative and market event messages
New IP addresses for the updated Nasdaq GEMX Data Feeds will be posted on UDP/IP Addresses – U.S. Derivatives Data Feeds once available.
Heartbeat availability for connectivity testing will be updated when available for both:
- New York Metro Area – “A” and “B” Feeds: Monday, August 7, 2023
- Chicago Metro Area – “A” and “B” Feeds: Monday, August 7, 2023
