Re: [Quickfix-developers] UseDataDictionary and repeating groups

[Dale W. <wil...@oc...>]

Hi Alvin,

I'd suggest option 2.  If you and a counterparty have agreed (if only by 
decree from the counter party) on an extension to the protocol, adding 
it to a custom dictionary for that counterparty documents and validates 
the agreement.

In fact the software I work on presently interacts with 5 different 
exchanges and each of them has it's own dictionary. (Exchanges do like 
their custom fields ;-}  )  Each of these custom dictionaries is an 
extension of the original FIX42.xml file.

On your other question.  There is nothing in the message itself that 
delimits the beginning and ending of a group and the boundaries between 
group entries other than the knowledge of which tags represent group 
counts, and which tags MUST appear as the first field within each group 
entry so without either a dictionary or many, many hard coded magic 
numbers (shudder) messages containing groups cannot be reliably decoded.
