FIX Field 528
Designates the capacity of the firm placing the order.
(see Volume : "Glossary" for value definitions)
Error in FIX Specification:
The spec (above) refers the reader to the Glossary for value definitions - but in fact the glossary only contains a definition for R Riskless Principal. It would be good to either add glossary definitions for the other values or remove the reference to the glossary.
