Hi,

One of the advantages of FIX is that it is extendable and possible to use it in ways that were not originally thought of.
Having said that, I would recommend always trying to stick to the standards where possible.
If the fields that you require are not present, try looking here to see if someone has already created a user defined field that could suit your purpose:
http://www.fixprotocol.org/specifications/fields/5000-5999

If you need to create a new field, you can register it here - ideally give it a generic name (i.e. not including your company name) so that other people can use it later.

I would recommend not to create a new message because it would probably be more work for your counterparty in the long run.

Cheers,
George.
