Hello,

Suppose we want to replace an order by another.
Do we have to provide ALL orders attributes (including the ones who don’t change) or just the ones who change?
Does the FIX specs mention this somewhere explicitly? Any pointer would be appreciated.

Thanks,
Pierre

Pierre,
The 4.3 and 4.4 specs state that the full order must be restated in the replace request:
"All of the application-level fields in the original order should be retransmitted with the original values in the Order Cancel/Replace Request, except the fields that are being changed." There is similar wording going back to the 4.0 spec.
