As previously announced CME Group will be migrating all GreenX products to a CME Group exchange, delisting them from the Green Exchange and listing them on NYMEX. The date of this migration will occur on Saturday morning August 25th for business date Monday, August 27th.
The sole impact of this change to clearing and bookkeeping systems is that the exchange acronym of the various products will change from GEX to NYMEX. There are no product code changes, firm change or other impacts. There will cease to be a separate Green Exchange settlement price file, and the daily SPAN files will no longer contain data for a separate Green Exchange.
The change was made effective in the New Release testing environment on June 18th to enable firms to test their systems with this change. For more information please contact CME Clearing Operations at (312)-207-2525 or via email to email@example.com.
These products are currently available in New Release with the new tag 207 value XNYM for customer testing.
Please Note: For the August 26 launch, customers are asked to please cancel all Good ’Till Cancel (GTC) and Good ’Till Date (GTD) orders for Green Exchange futures and options after their respective closes on Friday, August 24. After 16:30 CT on Friday, August 24, all remaining GTC and GTD orders for these products will be cancelled by the Global Command Center (GCC). GTC and GTD orders may be re-entered during the pre-open period on Sunday, August 26. If you have any questions, please contact the GCC in the U.S. at +1-312-456-2391 or in Europe at +44-20-7623-4708.
