it appears to be well coordinated too: just now on bitstamp a 500BTC ask wall appeared at 118.35
I am curious how much movement this will generate...
I'll wager a prediction: if the price does move down, those two walls will follow.
Then again, I can't image how they expect to get much movement at current volume, with 2000BTC needed just to get below 122BTC on mt.gox.
Hmmm...interesting. I see the one on Stamp and that's probably going to mess with my plans. At least we have something to look at, even if it turns out to be nothing.
