Everyone else is playing with lunch money. For this rally to get wings it needs to take out $16.50. Personally I don't think running this market up is their idea right now. Feels like testing to me.
I think you are wrong, all big orders during today were 1000-BTC strong. This is lunch money for many, and when 10 of such traders get their sentiment in one direction, we see a spike like today. Some real money would've just washed out all of the MtGox ASKs and the price would be in the thousands now.
