ClOrdID for Cancel Request message

hi everyone,

I’m curious as to why a new ClOrdID is required for the cancel request message. If it’s used for a partial cancel I guess it’s a possibility but if it’s used for a FULL cancel then shouldn’t the current ClOrdID of the order sufficient? I do know the specification mentions that the ClOrdID is there as it’s considered as a new entity but I’m wondering if it’s actually required.

Please comment.

thanks,

The structure of the message is to send a new ClOrdID with every new request. In effect the message is a request to cancel the open order. If the order ID is 1 for example then the cancel states this is a message that contains id 2 to cancel the order under id 1. If the cancel request is accepted, the answer from the destination is a confirm cancel of the order so FIX tag 39=4 with 11=1 will be received from the destination.

In FIX 4.2, it is more usual for the Execution Report Cancel Accept to arrive with 39 OrdStatus = 4, and 11 ClOrdID = 2, with 41 OrigClOrdID bearing the reference to the original order, 1.

A response with 11 = 1 is more along one of the two favoured styles for FIX 4.0.

I agree with both parties but my question still prevails.
If partial cancelling concept doesn’t exist in FIX 4.2 why do we need to name a new client order id when we just need to say in layman terms,

“Please cancel order with client order id” and i dont need to say now I’m calling the cancelled order with my “new client order id”. I totally understand that it’s the way protocol works but im curious as to whether this is a purely protocol or whether there’s a use of it in a particular scenario.

Heshan,

Its required for specific scenarios. Consider partial fills on cancel requests…
