Let me get this correct... So when the price spiked up and people were trading on Mt.Gox at $4.5,  Zhoutong's genius matching algorithm put the buy price at a $1 spread and force liquidate people's position at $4.9 ?? 

So when all these forced buy bitcoins are actually bought in Mt.Gox market at any price around $4.1-4.5, the all difference goes into Bitcoinica's pocket?

I've been Zhoutonged good!!!
