A quick look at the two market pages would have me giving btct.co the award for overall exchange action right now.
I suspect it is because people are able to place bids across assets with the same funds, meaning btct.co has a nicer bid side to sell into.
https://bitfunder.com/market vs
https://btct.co/security ....
mind you it is hard to be sure as one shows 7 day volume, the other 48 hour.
and yet, over on BitFunder the g.sdice stock has had much much more volume traded, 10's of thousands of shares traded vs the 61 gsdpt that have moved over at btct.co
looking through the trade history it seems to be mostly big buys, people taking advantage of the good deals.
