Preamble

Whereas:

1. (1)

   In order to reduce costs for market participants when purchasing data, Regulation (EU) No 600/2014 provides for pre-trade and post-trade transparency data to be made available to the public in an "unbundled" fashion for separate data items. It is necessary to specify the level of disaggregation by which venues should offer data. Taking into account the evidence of demand for such data from other stakeholders, market operators and investment firms operating a trading venue should disaggregate data by asset class, by country of issue, by the currency in which a financial instrument is traded, and according to whether data comes from scheduled daily auctions or from continuous trading.

2. (2)

   To ensure that pre-trade and post-trade data offered appropriately matches the demand from market participants, market operators and investment firms operating a trading venue should offer any combination of the disaggregation criteria on a reasonable commercial basis.

3. (3)

   For some financial instruments such as for derivatives it may not always be possible to determine unambiguously the particular asset class to which that instrument belongs since the determination of an asset class depends on which characteristics of the financial instruments are considered to be the decisive ones. Similarly, it may not always be possible to unambiguously determine which other criteria a type of data meets. To ensure that market participants purchasing data from a particular trading venue receive a consistent data set, it is necessary to require market operators or investment firms operating a trading venue to determine in those cases where the disaggregation criteria cannot be applied in an unambiguous manner which criteria a financial instrument or type of data should be deemed to meet.

4. (4)

   For reasons of consistency and in order to ensure the smooth functioning of the financial markets, it is necessary that the provisions laid down in this Regulation and the provisions laid down in Regulation (EU) No 600/2014 apply from the same date.

5. (5)

   This Regulation is based on the draft regulatory technical standards submitted by the European Securities and Markets Authority (ESMA) to the Commission.

6. (6)

   ESMA has conducted open public consultations on the draft regulatory technical standards on which this Regulation is based, analysed the potential related costs and benefits and requested the opinion of the Securities and Markets Stakeholder Group established by Article 37 of Regulation (EU) No 1095/2010 of the European Parliament and of the Council,
