Jaws

This is an animation of the order books in a simple supply and demand experiment. Trading prices and time are graphed in green on the left. To the right, the order books are graphed, with the best price offers on the left and the worst offers on the right. By looking at the books, you might want to guess whether the price is going to go up or down. The y axis measures price. The x axis measures time from the left to the jaw hinge and to the right of the hinge it measures quantity.
These animations require Netscape and a QuickTime plugin to view. The diagram explains what each data series in the jaws graph means.
