Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2014/65/EU of the European Parliament and of the Council of 15 May 2014 on markets in financial instruments and amending Directive 2002/92/EC and Directive 2011/61/EU, and in particular points (a), (c) and (g) of Article 48(12) thereof,


  1. (1)

    It is important to ensure that trading venues that enable algorithmic trading have sufficient systems and controls.

  2. (2)

    The provisions of this Regulation should apply not only to regulated markets but also to multilateral trading facilities and organised trading facilities as determined by Article 18(5) of Directive 2014/65/EU.

  3. (3)

    The impact of technological development and in particular algorithmic trading is one of the main drivers to determine the capacity and arrangements to manage trading venues. The risks arising from algorithmic trading can be present in any type of trading system that is supported by electronic means. Therefore, specific organisational requirements should be laid down in respect of regulated markets, multilateral trading facilities and organised trading facilities allowing for or enabling algorithmic trading through their systems. Such trading systems are those where algorithmic trading may take place as opposed to trading systems in which algorithmic trading is not permitted, including trading systems where transactions are arranged through voice negotiation.

  4. (4)

    Governance arrangements, the role of the compliance function, staffing and outsourcing should be regulated as part of the organisational requirements to ensure the resilience of electronic trading systems.

  5. (5)

    Requirements should be laid down with respect to the systems of trading venues allowing or enabling algorithmic trading. However, their specific application should take place in conjunction with a self-assessment to be conducted by each trading venue since not all trading models present the same risks. Therefore, some organisational requirements may not be appropriate for certain trading models although their trading systems could be supported to a certain extent by electronic means. In particular, the specific requirements to be set in relation to request-for-quote systems or hybrid systems should be considered according to the nature, scale and complexity of the algorithmic trading activity undertaken. Equally, more stringent requirements should be established by the trading venues where appropriate.

  6. (6)

    Risks arising from algorithmic trading should be carefully taken into account, paying particular attention to those that may affect the core elements of a trading system, including the hardware, software and associated communication lines used by trading venues and members, participants or clients of trading venues ("members") to perform their activity and any type of execution systems or order management systems operated by trading venues, including matching algorithms.

  7. (7)

    The specific organisational requirements for trading venues have to be determined by means of a robust self-assessment where a number of parameters have to be assessed. That self-assessment should include any other circumstances not expressly set out that may have an impact on their organisation.

  8. (8)

    The minimum period for keeping records of the self-assessment and the due diligence of members for the purpose of this Regulation should be the same as the general record-keeping obligations established in Directive 2014/65/EU.

  9. (9)

    Where trading venues are required to perform monitoring in real-time, it is necessary for the generation of alerts following that monitoring to be done as close to instantaneously as technically possible and therefore within no more than five seconds in order to be effective. For the same reason, any actions following that monitoring should be undertaken as soon as possible assuming a reasonable level of efficiency and of expenditure on systems on the part of the persons concerned.

  10. (10)

    Testing facilities offered by trading venues should not pose risks to orderly trading. To that end, trading venues should be required to establish an adequate fair usage policy, ensure a strict separation between the testing environment and the production environment or permit testing only out of trading hours.

  11. (11)

    Conformance testing should ensure that the most basic elements of the system or the algorithms used by members operate correctly and according to the venue's requirements, including the ability to interact as expected with the trading venue's matching logic and the adequate processing of data flows to and from the trading venue. Testing against disorderly trading conditions should be designed with a view to specifically addressing the reaction of the algorithm or strategy to conditions that may create a disorderly market.

  12. (12)

    Where trading venues offer arrangements to test algorithms by offering testing symbols, their obligation to provide facilities to test against disorderly trading conditions should be deemed to be fulfilled. In order to enable members to effectively use such testing symbols, trading venues should publish the specifications and characteristics of the testing symbols to the same level of detail made publicly available for real life production contracts.

  13. (13)

    Trading venues should be subject to an obligation to provide means to facilitate testing against disorderly trading conditions. However, their members should not be required to use those means. It should be considered as a sufficient guarantee if trading venues receive a declaration from their members confirming that such testing has taken place and stating the means used for that testing, but the trading venues should not be obliged to validate the adequacy of those means or the outcome of that testing.

  14. (14)

    Trading venues and their members should be required to be adequately equipped to cancel unexecuted orders as an emergency measure if unexpected circumstances arise.

  15. (15)

    The provision of direct electronic access (DEA) service to an indeterminate number of persons may pose a risk to the provider of that service and also to the resilience and capacity of the trading venue where the orders are sent. To address such risks, where trading venues allow sub-delegation, the DEA provider should be able to identify the different order flows from the beneficiaries of sub-delegation.

  16. (16)

    Where sponsored access is permitted by a trading venue, prospective sponsored access clients should be subjected to a process of authorisation by the trading venue. Trading venues should also be allowed to decide that the provision of direct market access services by their members is subject to authorisation.

  17. (17)

    Trading venues should specify the requirements to be met by their members in order for them to be allowed to provide DEA and determine the minimum standards to be met by prospective DEA clients in the due diligence process. Those requirements and standards should be adapted to the risks posed by the nature, scale and complexity of their expected trading, and the service being provided. In particular, they should include an assessment of the level of expected trading, the order volume and the type of connection offered.

  18. (18)

    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 related national provisions transposing Directive 2014/65/EU apply from the same date.

  19. (19)

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

  20. (20)

    The European Securities and Markets Authority 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,
