Bunched Orders

Imported from previous forum

Yes but then how would we do that for sub-accounts across different executing firms?

Hello, is it possible to implement the concept of bunched orders in FIX such that a single order contains two quantities for two customer accounts?

You can use of pre-allocation tags in New Order Singe if you are talking about Sub-accounts.
Example: 78=2 79=Acct1 80=1000 79=Acct2 80=2000 if Order quantity is 3000.
