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.
