Implementation Guidelines

FIX MiFID II Data Elements Recommended Practice Guidelines

The primary intention of this MIFID II Data Elements and their Authoritative, Master and Primary Sources Recommended Practice Guideline V1.3 document is to catalogue the mapping of MIFID II key data elements to existing data sources. Whilst a reference term for these data sources may be agreed by the industry, it is recognised that naming conventions may differ per market participant. Therefore, the intention of this document will focus exclusively on specifying mapping of these key data elements to data sources and does not seek to provide input related to the naming conventions for the data sources.


MiFID/MiFIR II Trade Reporting Implementation Guidelines

These guidelines provide guidance on implementing the requirements for post trade transparency (referred to in this document as ‘trade reporting’, being a generally accepted term). Much of this material is based on “Standards for the Consolidation of Trade Reports and Market Data in Europe” from the FIX EMEA Trade Data Standardisation Working Group, December 2013, with updates made to bring the text in line with the relevant MiFID II level 2 text (also included).
