During the lifetime of an order, the order identifer as seen by the Client and Venue "clOrdID" may change as a result of cancel-and-replace operations. By contrast, the identifer used internally by Whisperer does not change.

clOrdID string - Client Order ID
Allocated by: Customer Application at order submission when he submits a new order
Scope: Unique per (deal code, Trading Venue) during a sessionA string provided by the Customer Application. It should be unique per Feed, Customer Applica- tion, and Session. An error may be returned if two Customer Applications use the same clOrdID values to track different orders (however there is no guarantee that would happen because some venues just ignore duplicate orders). All Trading Actions and Events carry this field.
The Customer Application may leave that field empty and use only the MarketFactory Order Id described above everywhere except in the order submission.
To avoid problems, clOrdID values must be unique. To strike a balance between uniqueness and readability, a unique identifier may be constructed by the concatentation of company name, current timestamp, user id, and process id.
