I realize they can be taken down and moved very quickly, I guess I wasn't paying close enough attention to that price point. Anyone know if you can look at the full MtGox order book somewhere? I'd be interested in taking a look at it. BTW the wall is under 12K btc now.

Lemme refine my thought process further for academic sake...What if the sell wall was moved as a reaction to market movements? Perhaps traders had a feeling a downturn was coming and needed to liquidate their BTC into dollars to avoid losses so they lowered their ask. While I might have been wrong in this instance, I do stand by my thoughts on bids/sells congregating around nice even numbers.  I mean look at the orders at 5.4 and 5.2 you see walls the size of the one at 6.0, I truly believe there is a reason for this and it is not necessarily manipulation.
