It's also trading on air :
Buy orders
Total BTC: 267.65916849
That's a spike, I've seen sub 10 BTC volume on BTC-e usually.
I've started to think that people just won't trade advanced coins.
If it's advanced (in a good way), clever people that understand the coin hold it and don't sell, and dumb people that don't understand it don't buy -> low volume.
If it's a simple copycoin, clever people pump and dump, dumb people keep buying and placing sell orders to try to get their money back -> high volume.
