Hi,

please can someone tell me if a Execution report of new (in response) to a new order single is meant to be automatic or user initiated.

Or can it be both.

Also if it is acknowledged by the user, is there a time delay?.

i.o.w. Can the sell-side take its time in acknowledging the new order?

Regards
Byron

Hi Byron,

a new order single is meant to be automatic or user initiated.

It is automatic in the sense that you (the client or user) do not have to request it. But you can also send a OrderStatusRequest to get it.

Also if it is acknowledged by the user, is there a time delay?.

What do mean by “acknowledged by the user”? The time delay very much depends on the system used. If your FIX counterparty is just a gateway to a real exchange system, it could send a fast ExecReport(Pending New) to ack the receipt, and the real New comes later if the exchange replied.

AFAIK, the FIX protocol does not specify any timing.

Hi Jorg,

I originally picked up on the idea that the ack(ExecRep new) was an indication to the client (buy-side) that someone/something was actively taking the order onboard and working it and not a confirmation of delivery… Am I correct?

The problem is that we are adding FIX to a system that would easily do a lot of rejections AFTER acknowledgement. i.e. rejected one or two minutes after arrival of the new order single. Should we Ack and then Reject or just wait the minute ot 2 before rejecting or Acking?

Thanks again
Byron

Originally, as FIX was invented, it was a protocol between clients and broker. So the notion of “actively taking the order on board” applies to this situation. But nowadays FIX is also used to connect to exchanges and a lot of other purposes.

According to the FIX standard (see “Order State Change Matrices”), it is perfectly OK to send a “Rejected” after a “New”.

So you could send

(a) Rejected
(b) New - Rejected
(c) Pending New - Rejected
(d) Pending New - New - Rejected

AFAIK, the “Pending New” is mainly intended to answer OrderStatusRequest messages, but I guess it is OK to also use it for automatic replies.

If you feel that waiting 2 minutes is too long for your client, you may either insert a “Pending New” (or allow OrderStatusRequest to return it) or send a quick “New” and a “Rejected” later.

In summary: Choose what fits your (and your clients) needs best.

Please do not hesitate to post possible scenarios for further discussion
Hopefully, some other forum reader participate with their “best practices.”

Hi Byron,
I agree with what Jorg says.

However in my experience on the cash trading side of things I have
seen the sell-side sending a ‘Pending New’ to indicate that their
trading system has received the order but that the order has not been
rejected or accepted by the desk. The sales trader (or whoever) can
then accept or reject the message.

For DMA however the pending ack is usually deemed unnecessary
because the exchange responds (or should) in a timely fashion).

thanks,
Kevin
