IT – INET – Reminder FIX DROP for OUCH Enhancements (86/14)

NASDAQ OMX Nordic and NASDAQ OMX Baltic will enhance the FIX DROP for OUCH messages by adding the OUCH Port ID of the original order (“Source”) to the FIX DROP for OUCH outbound messages.


Background:
OUCH orders are identified by a Token (client order ID), provided by the client. The Token must be unique for each order passed over a single OUCH port.

When clients submit OUCH orders over many ports, they have the option to use the same unique Token value on different ports. To allow Drop clients to chain order replacements to the original order, the OUCH Drop provide the port ID as a field (“Source”) in the order message. However, the FIX OUCH Drop does not include the OUCH port ID.

The FIX DROP for OUCH messages will be enhanced by adding the port ID in a new FIX tag [145] DeliverToLocationID.

The new field will be added to the FIX Session Level Standard Header message of the FIX Order Entry protocol specification v1.24. (Session level messages are described in the Order Entry protocol specifications, not the drop specifications.)

Note! The DeliverToLocationID [145] will only be provided in the FIX DROP for OUCH outbound messages. The field is ignored on inbound messages to INET Nordic.

 

Protocol specifications

An updated FIX Order Entry protocol specification v1.24 is available at NASDAQ OMX Technical Information website, under Future INET Nordic Protocol Specifications.

 

Correction of Original Order Price values

In addition to the above, NASDAQ OMX will correct an issue where in Execution Reports both the Trade Price (FIX Tag [31] - LastPx) and the Order Price (FIX Tag [44] - Price) has incorrectly contained the Trade Price. This will now be corrected and the Order Price (FIX Tag [44] - Price) will contain the price the order has on the book, in line with the FIX standard and the FIX DROP for OUCH messages protocol specification.

Time schedule

  • INET Test (OTF) – Sep 1, 2014
  • INET Production – Sep 22, 2014
