Future INET Nordic Protocol Specifications

INET Nordic Order Entry (OUCH, FIX) and respective FIX DROP protocol updates, in preparation for MiFID II

Nasdaq Nordic and Nasdaq Baltic have introduced changes to the order entry protocols to the INET Nordic trading system INET in preparation for MiFID II order record keeping requirements. MiFID II requires venues to store data on the parties involved in the order and, upon request, report those to relevant supervisory authorities.

Changes include additional fields to OUCH and FIX order entry and drop protocols related to identifying the Parties of the Order, Liquidity Provision and Algo identification. The protocols include new MiFID II required fields in outbound messages for the purpose of post-trade transparency, utilizing Market Model Typology (MMT) standard trade flags.

In Production and INET Test NTF, the MiFID II fields are optional on inbound messages until November 20, 2017, from when the fields related to short codes will be mandatory (according to the specification). MiFID II fields are activated in the new INET Test M2 environment for proper testing of MiFID II functionality and conformance testing.

Latest changes:

  • Introduction of Party Role Qualifier to identify if the entered short code is a LEI, National ID or an Algo ID, adding support of six short code series for Order Record Keeping.
  • Introduce a DEA field on inbound messages, making it possible for DEA customers to override the default configured DEA setting on DEAL orders (own account).
  • Replacing existing FIX Tag [2667] - AlgoIndicator on inbound messages with a new value to existing FIX Tag [2594] - OrderAttributeType. FIX Tag [2667] remains on outbound messages indicating if a trade (fills) was a result of a firm engaged in algorithmic trading.
  • Added mapping information to the Order Capacity fields values to the MiFID II Trading Capacity values AOTC, MTCH, and DEAL.
  • Added reject codes (FIX, repeating group related).
  • Added displaycode “P” (Top-of-Book) to DisplayInst [9140] in FIX DROP for OUCH..

  • Updated PartyRoleQualifier [2376] with value 0 (NONE) to be used together with Reserved Short Codes (0-3).

  • Added FIX Tags NoTrdRegPublications [2668], TrdRegPublicationType [2669] and TrdRegPublReason [2670] to the FIX DROP for OUCH specification.

  • Added a LIS indicator to TrdRegPublReason [2670], value 9.

  • Updated PartyID [448] value 3 = CLIENT to NORE and expanded the description of the field according to latest ESMA Guidelines for ORK and Transaction Reporting 

The below listed protocol changes are available in INET Test NTF, INET Test M2 and INET Production:

​Mandatory certification of the updated order entry protocols will be arranged during September-October, 2017.

Nordic Equity Last Sale (NLS) - New MiFID II compliant Trade Ticker protocol now with Off-Exchange trade messages in addition to On-Exchange messages
