Observe the following guidelines when you manually assign an attribute:
· When appended to orderDescription, the number and order of attributes cannot be changed.
· For any attribute that is not defined, use the value 'EMPTY' or {}. Since a string length is limited to 255 characters, we recommend using the open/close curly braces {}.
· A place order message for a simple stock limit day order looks as follows, with the primary exchange "ISLAND" separating the extended attributes:
