Hi,

Is tag 41 (OrigClOrdID) really necessary if we provide tag 37 (OrderID)? I've never seen a FIX API that required 41 in this way. (i.e. what does it matter if we don't provide the previous version of the order if we have the permanent identifier?)

Thanks.

OrderID should be enough cancel the order correctly, and will be used first to find the order.
If it is not provided OrigClOrdID will be used. If neither are provided the cancel will be rejected.
