[ESMA 70-872942901-35 MiFIR transparency Q&A, Q&A 2.2]

MiFIR and RTS 1 and RTS 2 intend to enable data-users to consume highly reliable and comparable sets of data in a fragmented market. This includes the trade flags and details defined by ESMA in Annex I of RTS 1 and Annex II of RTS 2. It is therefore important to ensure that trading venues, market operators and APAs efficiently disseminate unambiguous content.

RTS 1 and 2 do not require the use of a specific technical format (such as XML) for transporting and making data public. Encoding data feeds, including using binary digital feeds, for transportation purposes is therefore possible as long as it contributes to keeping the speed of transmission as close to real time as possible. What matters for meeting the post-trade transparency requirements in MiFIR and RTS 1 and 2 is that post-trade data is published as soon as possible and that the details and flags specified in Annex II of RTS 1 and 2 are used.

Trading venues and APAs have to make sure that at the point of converting digital real-time feed into human readable data points the details and flags as specified in Annex I of RTS 1 and Annex II of RTS 2 are used.
