CME MDP 3.0 is now.Sep 24
On Sunday, 27th September, the CME MDP 3.0 feed becomes the sole "Feed of Record".
And the FIX/FAST based MDP feed will be decommisioned on 30th October. This means that if you've not already updated to support CME MDP 3.0, then you're running out of time.
OnixS provides CME MDP 3.0 Market Data Handler implementations that ease this migration and work "out of the box"...
