Elimination of Exchange-Defined Options Strategies on CME Globex
To allow more time for trader education and systems’ readiness, CME Group has postponed the planned delisting of all options EDS until November 1, 2009.
CMEG currently prelists approximately 360,000 options spreads per week, known as Exchange-Defined Spreads (EDS). Less than 1% of the more than 360,000 EDS have activity. Due to customer and system provider demand, CMEG has chosen to remove all EDS and make all option strategies user defined. A User-Defined Spread (UDS) is an option spread that a trader creates by defining the spread's legs and ratios. CME Globex receives these legs and creates a tradable instrument that is disseminated to the entire market. If the created spread matches a known CMEG spread type (e.g., straddle), CME Globex will properly identify the spread as that type.
On November 1:
The following resources are available for UDS functionality:

Please note: as a result of the reduced message response times, bandwidth utilization in these futures markets may ultimately increase by as much as 20%. Title
The messaging and functionality impacts are documented online in the Please note: all Equity Good 'Till Cancel (GTC) and Good 'Till Date (GTD) orders will be deleted from CME Globex prior to the open on launch weekend. We recommend all system providers supporting Equity futures test these changes thoroughly in New Release. |
