This Friday, May 18, 2007, CME ^® will be conducting an additional ticker test for the new ITC 2.1 Price Indicator “B” and Zero Price messages.  This test will include data for:

o       Category Code B – Bid/Ask (with size) Globex only

o       Category Code T – LAST (with volume) Globex only

o       Category Code A – LAST (no volume) Trading Floor only

o       Category Code N – Bid/Ask & LAST (with size/volume) Trading Floor only. 

Ticker testing will be held at approximately 4:45 p.m. Central Time.

Please be aware that zero pricing is initially being implemented to accommodate Snowfall and Average Weekly Temperature products; however, it may apply to other new product types we anticipate launching in the future.  In addition, zero pricing may apply to both floor-traded and CME Globex ^® -traded products.
