We want to use some custom Tag number in our internal reference which is not colliding with FIX Tag/Field number. So what is the maximum Tag/Field used in FIX protocol.

I can search in FIXimate till 1504.

Thanks,
Sunil.

Hi both,

the FIX protoco defines two ways to extend the protocol by new tag numbers:

  1. User defined fields (see Ashwaqs reply below):

    • Range 5000–9999 (already used up)
    • New range 20000–39999

  2. Internal field in a range higher than 10000 (except the new range above of course).

If your new fields are really internal and never meant to sent out to some other party, you may use 2. internal fields. Otherwise, you should
look into the user defined fields if some field suits your needs or you
have to define a new one.

You may also consider to use a already defined field from a higher FIX version in a lower FIX version (“User Defined Occurrence”).

What kind of field to you intend to insert?

Cheers, Jörg
