To handle increased trading volume in its stocks, the nyse introduced the:

Super Display Book  
It is very helpful to the floor brokers at NYSE because they use it to manage their work/order flow.The display book sidesteps the floor merchant and sends the request ideal to the expert/DMM for execution. Most client requests will never be dealt with by a stock dealer as they cannot hold an inventory . Floor dealers generally just handle the huge complex institutional requests. Client requests will be electronically steered specifically to the exchanging post for execution by means of the super show book framework.

An attractive economy.
