Click on Q4 2012: http://www.cmegroup.com/market-data/distributor/market-data-platform.html I've been looking for something like this for a while and thought I would share...
Not a thread title I ever expected to see in "Data Sets and Feeds"! LOL But yes, is interesting... thanks for sharing ... I guess "number of messages" loosely relates to trading dimensions like "liquidity", "presence of HFT players", etc ... No? No surprise that ES (Channel 7) is high. For the rest, I guess you'd need to know how many different contracts were represented by each channel (e.g. Channel 11 is 6E, 6B, etc ... whereas Channel 7 is just ES) to assess what they mean ...
