No actually hang on a second, as usual i was dead right. If you go to that link, and go to the top result it will take you to Eurex's statistics page, go to 'monthly statistics' link on the left hand side and you can get a monthly breakdown of volume by product since Nov 1998. Which is much more helpful than i thought they would be for such arseholes, maybe they had an off day. LIFFE also has an average daily volume breakdown spreadsheet which is pretty good but i don't think it goes back as far.
