Book-to-book tranfer message

Imported from previous forum

Hello,

We are trying use FIX for our book-to-book transfers, but do not seem to be able to find a suitable msg. It is a very simple transfer stating the basics of the order (security, quantity, book from, book to, is reporting, is net and few other fields - not neccessary fix)

Is there a msg we can use (possibly type ā€˜s’ New Order - Cross) or should we create a new U-type message?

Thanks,

Andrej
