There seems to be some clear support. When the price goes down, even more, I've seen as much as 30k BTC of buy orders and this support seems very real. Also when the price goes down a bit more the sell order book sometimes becomes as low as 30% of the buy order book, or around 10k of BTC.
You'll have to click on "all" under the graph to see what I'm talking about.
