It's also interesting that ioffer.com isn't even on that list. Unless I am overlooking it.
Yep, that's the first thing that struck me, but they are daily figures and if ioffer had a bad day then maybe their stats weren't good enough to make that particular list.
Actually they are even more limited than daily figures, measuring up against the same hour from the previous day. Would be good to find the same kind of stats, just based on the whole days trading, not from any particular hour.
If anyone has a link, post it up!
