4.2 Allocation Message

Imported from previous forum

Summary: Can I send a fix 4.4 Allocation Message over a 4.2 session.

I have buffer limits for fix communication between the fix server and the server feeding the allocation message.

If an allocation exceeds the buffer size, can I used fix 4.4 (with partial allocations) to send it?

Is it allowed to send different fix version messages on the same session?

Hello

As far as I’m aware it’s not possible to send 4.4 messages over a 4.2 FIX session, though I’ll defer to the Technical Committee for any comments they may have regarding this. It sounds like you’re after the message fragmentation feature in 4.4 to enable you to split your allocation messages up. 4.2 doesn’t support this, in fact the spec does state that when using teh Allocation message ‘The total shares allocated must equal the Shares value which must equal the total executed quantity of the original order.’

Best regards
