Central Limit Order Book
A proposed database for all limit orders received by specialists and market makers throughout the United States. Such a system would allow limit orders to be fulfilled immediately or later, depending on the nature of the order, on any American exchange. The SEC proposed the establishment of CLOB, but it never occurred because most exchanges believe that such as a database would cause them to lose trading volume.
