Bitfinex shows ~14K BTC volume on this latest move, if the wall were fake why did the move up cause more volume then the order book was showing at the time.
2000 BTC took Bitfinex up to $599. Just further couple of hundred BTC took it up to $630, and then a few hundred more caused it to correct to $583. All within one minute. Who in their right mind (human mind or bot coding) is going to be so chomping at the bit to get in on Bitcoins that they are happy to pay up $30 above the USD market standard rate (Bitstamp price)?
Why do these things never happen on Bitstamp?
Why is it only ever on shady exchanges like BTC-e and Bitfinex that we get these wild anomalous trading spikes?
Did you know that Bitfinex routes trades through Bitstamp to increase liquidity? Seems to have circumvented Bitstamp on this occasion hasn't it not?
Have you actually traded on Bitfinex? Have you first hand experience of all it's little 'quirks'? Especially with regards to farming Stop Loss orders!
These exchanges will one day prove to be a blight on the Bitcoin market just like Gox did.
