Looking at the depth chart, there seems to be a lot more bouncing to come. Good call though. Sometimes I wonder if people even look at the open orders before they make decisions.
How do you go about this?
My favorite source is
http://bitcoin.clarkmoody.com/ It has all of the open orders nicely displayed in real time... at least when volume isn't so high it takes mtgox 10 minutes to open an order.
mtgoxlive.com/orders gives a nice visual of the same data.
I tend to use both simultaneously. Sometimes open orders can be misleading though. They shouldn't be the only thing you are basing your orders on.
