Detailed Description

MessageBase Aug 11, 2004.

A base class for messages in a market trading system. The "product" might be an computer driven trading program. The user is the identifier for the person who started the product or who is using a manual entry trading system. The local ID is an ID that is meaningful to the trading product.
