PartyRole Value 11
Buyside trader id associated with Order Origination Firm which originates/submits the order.
Error in FIX Specification:
The Glossary (Spec volume 1) refers to "Order Originator". It might be clearer if it referred specifically to the two Order Origination values - this one and PartyRole/13 OrderOriginationFirm. In addition the entry for "Order Originator" and the entry before it are out of alphabetical order in the glossary.
