The MMT (Market Model Typology) Initiative is a collaborative effort established by a broad range of industry participants (trading/reporting venues, data vendors and buy/sell side participants). The initiative is committed to achieving a practical and common solution for standards on post-trade data across all asset classes subject to MiFID II. The initiative unites a variety of industry participants in the basic belief that we can and should act without any further delay to improve the consistency and comparability of data from different sources.

To achieve this goal, we have developed the Market Model Typology (MMT) project, which found its original inspiration in the 2010 CESR Technical Working Group recommendations. The latest MMT version delivers an efficient operational solution for fulfilling trade flagging requirements raised in MiFID II RTS 1 and RTS2. The model is available for immediate adoption and can be used by vendors and clients. In addition to the work on standards for RMs and MTFs, we continue to attract wide-ranging industry support for the standards and are working to expedite their broad implementation, notably to define OTC trading reporting rules.

In order for the MMT standards to become more widely recognised and adopted, the MMT Steering Committee has voted to bring the initiative under the jurisdiction of the FIX Protocol Limited Trust (Trust). With its long-established and respected values and governance standards, the Trust will oversee the management and development of the standard.
