Pending New & New | LMP2, 3, 6

Imported from previous forum

Hi,

We are working on the IPL instrumentation of our Trading Platform and were wondering about some technical points.

On receiving a new Order, our system responds with a “Pending New” Exec.Report, followed by a “New” or “Reject”. In effect, these correspond to an LMP E1 -> E2 -> E3 -> E6 -> E7 -> E8 path travelled like this:

Order -> E1 -> E2 -> E3
E8 <- E7 <- E6 <- Exec. Report

If we try to be precise, at what LMP is the Order Validated/Authorised (determined as acceptable or to be rejected), LMP E3 or LMP E6 ?

Finally, from what LMP is the FIX gateway responding “Pending New” (which is not part of Validation/Authorisation process yet), LMP E3, E6 or even E2 ?

Thank you for any information,
Franck

Hi Franck,

It looks like the diagram in: http://www.fixprotocol.org/documents/5936/Reference%20Topologies%20w%20text%20v4.pdf
may benefit from addition detail.

Specifically, it looks like the Accept/Reject happens in E6 which means that the diagram is missing an arrow between E3->E7 for ‘Pending New’.

So,
Order submit → Pending New : E1 → E2 → E3 → E7 → E8
Order submit → Accept/Reject: E1 → E2 → E3 → E6 → E7 → E8

According to above, the ‘Pending New’ is generated by E3, whilst the Ack/Reject by E6.

Hope this helps,
Yuval
