Hi all,
The orderbook is the heart of any exchange (imho). if we can give users concentrated information with the colors used to represent the orderbook would be great. please see example.
Sorry for the bad art skills iCode 
- the red vertical line represent the position of my order between the green color representing the size/ratio of the orders on this price.
- Green bar shows the ratio of this order price against 3 which shows the ratio of all orders above this price.
