Commission Delegated Regulation (EU) 2017/589
of 19 July 2016
supplementing Directive 2014/65/EU of the European Parliament and of the Council with regard to regulatory technical standards specifying the organisational requirements of investment firms engaged in algorithmic trading
(Text with EEA relevance)

THE EUROPEAN COMMISSION,
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 amending Directive 2002/92/EC and Directive 2011/61/EU, and in particular points (a) and (d) of Article 17(7) thereof.
OJ L 173, 12.6.2014, p. 349.
Whereas:
(1) Systems and risk controls used by an investment firm engaged in algorithmic trading, providing direct electronic access or acting as general clearing members, should be efficient, resilient and have adequate capacity, having regard to the nature, scale and complexity of the business model of that investment firm.
(2) To that end, an investment firm should address all risks that may affect the core elements of an algorithmic trading system, including risks related to the hardware, software and associated communication lines used by that firm to perform its trading activities. To ensure the same conditions for algorithmic trading independently of trading form, any type of execution system or order management system operated by an investment firm should be covered by this Regulation.
(3) As a part of its overall governance framework and decision making framework, an investment firm should have a clear and formalised governance arrangement, including clear lines of accountability, effective procedures for the communication of information and a separation of tasks and responsibilities. That arrangement should ensure reduced dependency on a single person or unit.
(4) Conformance testing should be made in order to verify that the trading systems of an investment firm communicate and interact properly with the trading systems of the trading venue or of the direct market access (DMA) provider and that market data are processed correctly.
(5) Investment decision algorithms make automated trading decisions by determining which financial instrument should be purchased or sold. Order execution algorithms optimise order-execution processes by automatic generation and submission of orders or quotes, to one or several trading venues once the investment decision has been taken. Trading algorithms that are investment decision algorithms should be differentiated from order execution algorithms having regard to their potential impact on the overall fair and orderly functioning of the market.
(6) The requirements concerning the testing of trading algorithms should be based on the potential impact that those algorithms may have on the overall fair and orderly functioning of the market. In this regard, only pure investment decision algorithms which generate orders that are only to be executed by non-automated means and with human intervention should be excluded from the testing requirements.
(7) When introducing trading algorithms, an investment firm should ensure controlled deployment of trading algorithms, regardless of whether those trading algorithms are new or previously have been successfully deployed in another trading venue, and whether their architecture has been materially modified. The controlled deployment of trading algorithms should ensure that the trading algorithms perform as expected in a production environment. The investment firm should therefore set cautious limits on the number of financial instruments being traded, the price, value and number of orders, the strategy positions and the number of markets involved and by monitoring the activity of the algorithm more intensively.
(8) Compliance with the specific organisational requirements for an investment firm should be determined according to a self-assessment which includes an assessment of compliance with the criteria set out in Annex I to this Regulation. That self-assessment should furthermore include all other circumstances that may have an impact on the organisation of that investment firm. That self-assessment should be made regularly and should allow the investment firm to gain a full understanding of the trading systems and trading algorithms it uses and the risks stemming from algorithmic trading, irrespective of whether those systems and algorithms were developed by the investment firm itself, purchased from a third party, or designed or developed in close cooperation with a client or a third party.
(9) An investment firm should be able to withdraw all or some of its orders where this becomes necessary (‘kill functionality’). For such a withdrawal to be effective, an investment firm should always be in a position to know which trading algorithms, traders or clients are responsible for an order.
(10) An investment firm engaged in algorithmic trading should monitor that its trading systems cannot be used for any purpose that is contrary to Regulation (EU) No 596/2014 of the European Parliament and of the Council or to the rules of a trading venue to which it is connected. Suspicious transactions or orders should be reported to the competent authorities in accordance with that Regulation.
Regulation (EU) No 596/2014 of the European Parliament and of the Council of 16 April 2014 on market abuse (market abuse regulation) and repealing Directive 2003/6/EC of the European Parliament and of the Council and Commission Directives 2003/124/EC, 2003/125/EC and 2004/72/EC (OJ L 173, 12.6.2014, p. 1).
(11) Different types of risks should be addressed by different types of controls. Pre-trade controls should be conducted before an order is submitted to a trading venue. An investment firms should also monitor its trading activity and implement real-time alerts which identify signs of disorderly trading or a breach of its pre-trade limits. Post-trade controls should be put in place to monitor the market and credit risks of the investment firm through post-trade reconciliation. In addition, potential market abuse and violations of the rules of the trading venue should be prevented through specific surveillance systems that generate alerts on the following day at the latest and that are calibrated to minimise false positive and false negative alerts.
(12) The generation of alerts following real time monitoring should be done as instantaneously as technically possible. Any actions following that monitoring should be undertaken as soon as possible having regard to a reasonable level of efficiency and expenditure of the persons and systems concerned.
(13) An investment firm providing direct electronic access (‘DEA provider’) should remain responsible for the trading carried out through the use of its trading code by its DEA clients. A DEA provider should therefore establish policies and procedures to ensure that trading of its DEA clients complies with the requirements applicable to that provider. That responsibility should constitute the principal factor for establishing pre-trade and post-trade controls and for assessing the suitability of prospective DEA clients. A DEA provider should therefore have sufficient knowledge about the intentions, capabilities, financial resources and trustworthiness of its DEA clients, including, where publicly available, information about the prospective DEA clients' disciplinary history with competent authorities and trading venues.
(14) A DEA provider should comply with the provisions of this Regulation even where it is not engaged in algorithmic trading, since its clients may use the DEA to engage in algorithmic trading.
(15) Due diligence assessment of prospective DEA clients should be adapted to the risks posed by the nature, scale and complexity of their expected trading activities and to the DEA being provided. In particular, the expected level of trading and order volume and the type of connection offered to the relevant trading venues should be assessed.
(16) The content and format of the forms to be used by an investment firm engaged in high frequency trading technique for submitting to the competent authorities the records of its placed orders and the length of time that those records should be kept should be laid down.
(17) To ensure consistency with the general obligation for an investment firm to keep records of orders, the required record keeping periods for an investment firm engaging in high-frequency algorithmic trading technique should be aligned with the ones laid down in Article 25(1) of Regulation (EU) No 600/2014 of the European Parliament and of the Council.
Regulation (EU) No 600/2014 of the European Parliament and of the Council of 15 May 2014 on markets in financial instruments and amending Regulation (EU) No 648/2012 (OJ L 173, 12.6.2014, p. 84).
(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) This Regulation is based on the draft regulatory technical standards submitted by the European Securities and Markets Authority (‘ESMA’) to the Commission.
(20) 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,
Regulation (EU) No 1095/2010 of the European Parliament and of the Council of 24 November 2010 establishing a European Supervisory Authority (European Securities and Markets Authority), amending Decision No 716/2009/EC and repealing Commission Decision 2009/77/EC (OJ L 331, 15.12.2010, p. 84).

SECTION 2 Post-deployment management

Article 9 Annual self-assessment and validation(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall annually perform a self-assessment and validation process and on the basis of that process issue a validation report. In the course of that process the investment firm shall review, evaluate and validate the following:
(a) its algorithmic trading systems, trading algorithms and algorithmic trading strategies;
(b) its governance, accountability and approval framework;
(c) its business continuity arrangement;
(d) its overall compliance with Article 17 of Directive 2014/65/EU, having regard to the nature, scale and complexity of its business.
The self-assessment shall also include at least an analysis of compliance with the criteria set out in Annex I to this Regulation.
2. The risk management function of the investment firm referred to in Article 23(2) of Commission Delegated Regulation (EU) 2017/565, shall draw up the validation report and, for that purpose, involve staff with the necessary technical knowledge. The risk management function shall inform the compliance function of any deficiencies identified in the validation report.
Commission Delegated Regulation (EU) 2017/565 of 25 April 2016 supplementing Directive 2014/65/EU of the European Parliament and of the Council as regards organisational requirements and operating conditions for investment firms and defined terms for the purposes of that Directive (see page 1 of this Official Journal).
3. The validation report shall be audited by the firm's internal audit function, where such function exists, and be subject to approval by the investment firm's senior management.
4. An investment firm shall remedy any deficiencies identified in the validation report.
5. Where an investment firm has not established a risk management function referred to in Article 23(2) of Delegated Regulation (EU) 2017/565, the requirements set out in relation to the risk management function in this Regulation shall apply to any other function established by the investment firm in accordance with Article 23(2) of Delegated Regulation (EU) 2017/565.

Article 10 Stress testing(Article 17(1) of Directive 2014/65/EU)
As part of its annual self-assessment referred to in Article 9, an investment firm shall test that its algorithmic trading systems and the procedures and controls referred to in Articles 12 to 18 can withstand increased order flows or market stresses. The investment firm shall design such tests, having regard to the nature of its trading activity and its trading systems. The investment firm shall ensure that the tests are carried out in such a way that they do not affect the production environment. Those tests shall comprise:
(a) running high messaging volume tests using the highest number of messages received and sent by the investment firm during the previous six months, multiplied by two;
(b) running high trade volume tests, using the highest volume of trading reached by the investment firm during the previous six months, multiplied by two.

Article 11 Management of material changes(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall ensure that any proposed material change to the production environment related to algorithmic trading is preceded by a review of that change by a person designated by senior management of the investment firm. The depth of the review shall be proportionate to the magnitude of the proposed change.
2. An investment firm shall establish procedures to ensure that any change to the functionality of its systems is communicated to traders in charge of the trading algorithm and to the compliance function and the risk management function.

SECTION 3 Means to ensure resilience

Article 12 Kill functionality(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall be able to cancel immediately, as an emergency measure, any or all of its unexecuted orders submitted to any or all trading venues to which the investment firm is connected (‘kill functionality’).

3. For the purposes of paragraph 1 and 2, an investment firm shall be able to identify which trading algorithm and which trader, trading desk or, where applicable, which client is responsible for each order that has been sent to a trading venue.

Article 13 Automated surveillance system to detect market manipulation(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall monitor all trading activity that takes place through its trading systems, including that of its clients, for signs of potential market manipulation as referred to in Article 12 of Regulation (EU) No 596/2014.
2. For the purposes of paragraph 1, the investment firm shall establish and maintain an automated surveillance system which effectively monitors orders and transactions, generates alerts and reports and, where appropriate, employs visualisation tools.
3. The automated surveillance system shall cover the full range of trading activities undertaken by the investment firm and all orders submitted by it. It shall be designed having regard to the nature, scale and complexity of the investment firm's trading activity, such as the type and volume of instruments traded, the size and complexity of its order flow and the markets accessed.
4. The investment firm shall cross-check any indications of suspicious trading activity that have been generated by its automated surveillance system during the investigation phase against other relevant trading activities undertaken by that firm.
5. The investment firm's automated surveillance system shall be adaptable to changes to the regulatory obligations and the trading activity of the investment firm, including changes to its own trading strategy and that of its clients.
6. The investment firm shall review its automated surveillance system at least once a year to assess whether that system and the parameters and filters employed by it are still adequate to the investment firm's regulatory obligations and trading activity, including its ability to minimise the generation of false positive and false negative surveillance alerts.
7. Using a sufficiently detailed level of time granularity, the investment firm's automated surveillance system shall be able to read, replay and analyse order and transaction data on an ex-post basis, with sufficient capacity to be able to operate in an automated low-latency trading environment where relevant. It shall also be able to generate operable alerts at the beginning of the following trading day or, where manual processes are involved, at the end of the following trading day. The investment firm's surveillance system shall have adequate documentation and procedures in place for the effective follow-up to alerts generated by it.
8. Staff responsible for monitoring the investment firm's trading activities for the purposes of paragraphs 1 to 7 shall report to the compliance function any trading activity that may not be compliant with the investment firm's policies and procedures or with its regulatory obligations. The compliance function shall assess that information and take appropriate action. Such action shall include reporting to the trading venue or submitting a suspicious transaction or order report in accordance with Article 16 of Regulation (EU) No 596/2014.
9. An investment firm shall ensure that its records of trade and account information are accurate, complete and consistent by reconciling as soon as practicable its own electronic trading logs with records provided by its trading venues, brokers, clearing members, central counterparties, data providers or other relevant business partners, where applicable and appropriate considering the nature, scale and complexity of the business.

Article 14 Business continuity arrangements(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall have business continuity arrangements in place for its algorithmic trading systems which are appropriate to the nature, scale and complexity of its business. Those arrangements shall be documented in a durable medium.
2. Business continuity arrangements of an investment firm shall effectively deal with disruptive incidents and, where appropriate, ensure a timely resumption of the algorithmic trading. Those arrangements shall be adapted to the trading systems of each of the trading venue accessed and shall include the following:
(a) a governance framework for the development and of the deployment of the business continuity arrangement;
(b) a range of possible adverse scenarios relating to the operation of the algorithmic trading systems, including the unavailability of systems, staff, work space, external suppliers or data centres or loss or alteration of critical data and documents;
(c) procedures for relocating the trading system to a back-up site and operating the trading system from that site, where having such a site is appropriate to the nature, scale and complexity of the algorithmic trading activities of the investment firm;
(d) staff training on the operation of the business continuity arrangements;
(e) usage policy regarding the functionality referred to in Article 12;
(f) arrangements for shutting down the relevant trading algorithm or trading system where appropriate;
(g) alternative arrangements for the investment firm to manage outstanding orders and positions.
3. An investment firm shall ensure that its trading algorithm or trading system can be shut down in accordance with its business continuity arrangements without creating disorderly trading conditions.
4. An investment firm shall review and test its business continuity arrangements on an annual basis and modify the arrangements in light of that review.

Article 15 Pre-trade controls on order entry(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall carry out the following pre-trade controls on order entry for all financial instruments:
(a) price collars, which automatically block or cancel orders that do not meet set price parameters, differentiating between different financial instruments, both on an order-by-order basis and over a specified period of time;
(b) maximum order values, which prevent orders with an uncommonly large order value from entering the order book;
(c) maximum order volumes, which prevent orders with an uncommonly large order size from entering the order book;
(d) maximum messages limits, which prevent sending an excessive number of messages to order books pertaining to the submission, modification or cancellation of an order.
2. An investment firm shall immediately include all orders sent to a trading venue into the calculation of the pre-trade limits referred to in paragraph 1.
3. An investment firm shall have in place repeated automated execution throttles which control the number of times an algorithmic trading strategy has been applied. After a pre-determined number of repeated executions, the trading system shall be automatically disabled until re-enabled by a designated staff member.
4. An investment firm shall set market and credit risk limits that are based on its capital base, its clearing arrangements, its trading strategy, its risk tolerance, experience and certain variables, such as the length of time the investment firm has been engaged in algorithmic trading and its reliance on third-party vendors. The investment firm shall adjust those market and credit risk limits to account for the changing impact of the orders on the relevant market due to different price and liquidity levels.
5. An investment firm shall automatically block or cancel orders from a trader if it becomes aware that that trader does not have permission to trade a particular financial instrument. An investment firm shall automatically block or cancel orders where those orders risk compromising the investment firm's own risk thresholds. Controls shall be applied, where appropriate, on exposures to individual clients, financial instruments, traders, trading desks or the investment firm as a whole.
6. An investment firm shall have procedures and arrangements in place for dealing with orders which have been blocked by the investment firm's pre-trade controls but which the investment firm nevertheless wishes to submit. Such procedures and arrangements shall be applied in relation to a specific trade on a temporary basis and in exceptional circumstances. They shall be subject to verification by the risk management function and authorisation by a designated individual of the investment firm.

Article 16 Real-time monitoring(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall, during the hours it is sending orders to trading venues, monitor in real time all algorithmic trading activity that takes place under its trading code, including that of its clients, for signs of disorderly trading, including trading across markets, asset classes, or products, in cases where the firm or its clients engage in such activities.
2. The real-time monitoring of algorithmic trading activity shall be undertaken by the trader in charge of the trading algorithm or algorithmic trading strategy, and by the risk management function or by an independent risk control function established for the purpose of this provision. That risk control function shall be considered to be independent, regardless of whether the real-time monitoring is conducted by a member of the staff of the investment firm or by a third party, provided that that function is not hierarchically dependent on the trader and can challenge the trader as appropriate and necessary within the governance framework referred to in Article 1.
3. Staff members in charge of the real-time monitoring shall respond to operational and regulatory issues in a timely manner and shall initiate remedial action where necessary.
4. An investment firm shall ensure that the competent authority, the relevant trading venues and, where applicable, DEA providers, clearing members and central counterparties can at all times have access to staff members in charge of real-time monitoring. For that purpose, the investment firm shall identify and periodically test its communication channels, including its contact procedures for out of trading hours, to ensure that in an emergency the staff members with the adequate level of authority may reach each other in time.
5. The systems for real-time monitoring shall have real-time alerts to assist staff in identifying unanticipated trading activities undertaken by means of an algorithm. An investment firm shall have a process in place to take remedial action as soon as possible after an alert has been generated, including, where necessary, an orderly withdrawal from the market. Those systems shall also provide alerts in relation to algorithms and DEA orders triggering circuit breakers of a trading venue. Real-time alerts shall be generated within five seconds after the relevant event.

Article 17 Post-trade controls(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall continuously operate the post-trade controls that it has in place. Where a post-trade control is triggered, the investment firm shall undertake appropriate action, which may include adjusting or shutting down the relevant trading algorithm or trading system or an orderly withdrawal from the market.
2. Post-trade controls referred to in paragraph 1 shall include the continuous assessment and monitoring of market and credit risk of the investment firm in terms of effective exposure.
3. An investment firm shall keep records of trade and account information, which are complete, accurate and consistent. The investment firm shall reconcile its own electronic trading logs with information about its outstanding orders and risk exposures as provided by the trading venues to which it sends orders, by its brokers or DEA providers, by its clearing members or central counterparties and by its data providers or other relevant business partners. Reconciliation shall be made in real-time where the aforementioned market participants provide the information in real-time. An investment firm shall have the capability to calculate in real time its outstanding exposure and that of its traders and clients.
4. For derivatives, the post-trade controls referred to in paragraph 1 shall include controls regarding the maximum long and short and overall strategy positions, with trading limits to be set in units that are appropriate to the types of financial instruments involved.
5. Post-trade monitoring shall be undertaken by the traders responsible for the algorithm and the risk control function of the investment firm.

Article 18 Security and limits to access(Article 17(1) of Directive 2014/65/EU)
1. An investment firm shall implement an IT strategy with defined objectives and measures which:
(a) is in compliance with the business and risk strategy of the investment firm and is adapted to its operational activities and the risks to which it is exposed;
(b) is based on a reliable IT organisation, including service, production, and development;
(c) complies with an effective IT security management.
2. An investment firm shall set up and maintain appropriate arrangements for physical and electronic security that minimise the risks of attacks against its information systems and that includes effective identity and access management. Those arrangements shall ensure the confidentiality, integrity, authenticity, and availability of data and the reliability and robustness of the investment firm's information systems.
3. An investment firm shall promptly inform the competent authority of any material breaches of its physical and electronic security measures. It shall provide an incident report to the competent authority, indicating the nature of the incident, the measures taken following the incident and the initiatives taken to avoid similar incidents from recurring.
4. An investment firm shall annually undertake penetration tests and vulnerability scans to simulate cyber-attacks.
5. An investment firm shall ensure that it is able to identify all persons who have critical user access rights to its IT systems. The investment firm shall restrict the number of such persons and shall monitor their access to IT systems to ensure traceability at all times.

CHAPTER III DIRECT ELECTRONIC ACCESS

Article 19 General provisions for DEA(Article 17(5) of Directive 2014/65/EU)
A DEA provider shall establish policies and procedures to ensure that trading of its DEA clients complies with the trading venue's rules so as to ensure that the DEA provider meets the requirements in accordance with Article 17(5) of Directive 2014/65/EU.

The DEA provider shall monitor the performance of the pre-trade and post-trade controls on an on-going basis.
3. The limits of the pre-trade controls on order submission shall be based on the credit and risk limits which the DEA provider applies to the trading activity of its DEA clients. Those limits shall be based on the initial due diligence and periodic review of the DEA client by the DEA provider.

(c) automatically block or cancel orders from a DEA client for financial instruments which that client is not authorised to trade, using an internal flagging system to identify and block single DEA clients or a group of DEA clients;
(d) automatically block or cancel orders from a DEA client that breach the risk management thresholds of the DEA provider, applying controls to exposures of individual DEA clients, financial instruments or groups of DEA clients;
(e) stop order flows transmitted by its DEA clients;
(f) suspend or withdraw DEA services to any DEA client where the DEA provider is not satisfied that continued access would be consistent with its rules and procedures for fair and orderly trading and market integrity;
(g) carry out, whenever necessary, a review of the internal risk control systems of DEA clients.
2. A DEA provider shall have procedures to evaluate, manage and mitigate market disruption and firm-specific risks. The DEA provider shall be able to identify the persons to be notified in the event of an error resulting in violations of the risk profile or in potential violations of the trading venue's rules.
3. A DEA provider shall at all times be able to identify its different DEA clients and the trading desks and traders of those DEA clients, who submit orders through the DEA provider's systems, by assigning a unique identification code to them.
4. A DEA provider allowing a DEA client to provide its DEA access to its own clients (‘sub-delegation’) shall be able to identify the different order flows from the beneficiaries of such sub-delegation without being required to know the identity of the beneficiaries of such arrangement.
5. A DEA provider shall record data relating to the orders submitted by its DEA clients, including modifications and cancellations, the alerts generated by its monitoring systems and the modifications made to its filtering process.

Article 22 Due diligence assessment of prospective DEA clients(Article 17(5) of Directive 2014/65/EU)

1. A DEA provider shall review its due diligence assessment processes annually.
2. A DEA provider shall carry out an annual risk-based reassessment of the adequacy of its clients' systems and controls, in particular taking into account changes to the scale, nature or complexity of their trading activities or strategies, changes to their staffing, ownership structure, trading or bank account, regulatory status, financial position and whether a DEA client has expressed an intention to sub-delegate the access it receives from the DEA provider.
