Dear CME Globex Customers,
To support the rollout of additional options contracts on the CME Globex electronic trading platform, the ISIN codes for several
instruments will be changing. The ISIN code is the 12 character alphanumeric identifier for each instrument listed on the
CME Globex platform and can be found in positions 1 through 12 of all contract-specific CME Market Data API (CME MD API) messages.
CME recommends that customers clear the ISIN codes from existing product tables and reacquire the ISIN codes from the CME
MD API MO (m-oh) message on a weekly basis.
These changes will be reflected in both the CME production and CME certification environment market data feeds beginning Sunday,
May 1, 2005, and will impact the following products:
- CME E-mini S&P 500® options and options spreads
- CME E-mini NASDAQ-100® options and options spreads
- CME E-mini Russell 2000® options and options spreads
- CME Euro FX options and options spreads
- CME Japanese Yen options and options spreads
- CME S&P 500 options
- CME NASDAQ-100 options
- CME S&P 500/Barra ValueTM options
- CME S&P 500/Barra GrowthTM options
For questions regarding this CME Globex change, please contact your CME Globex Account Manager at 312.634.8700 in North America or +1.44.207.623.2550 in Europe.
Thank you,
CME Globex Account Management
