Only need a 33k sell to be pushing a new low...
ATM bid and ask is slightly worse than the pre-crash, but a market order to the low 140's would fix that, as long as there is $$$ to fill the bids in.
Quite surprising how quickly it all went.
On topic. The rapid recovery from the SR news shows massive support in the market for the $130-140 level on mtgox ($120-125 on bitstamp).
Questionable. Its really hard to say anything until withdrawal issues are fixed.
Bistamp/BTC-E/etc. cant really separate fully from Gox because people wont sell for [Well, currently wont sell for...] less than ~$25 from Gox price. And it makes sense for it to be that way. If I could sell on bitstamp for $5 under Gox I would. But I cant. Others are willing to take bigger hits. But few would take less than 20% loss, preventing more separation.
Plus, like others said, the whole ordeal was just people hoping to buy back lower.
