As algorithmic trading strategies, including high frequency trading (HFT) strategies (hereinafter referred to collectively as "algorithmic strategies"), have grown to compose a substantial portion of activity on U.S. securities markets, the potential for these strategies to adversely impact market and firm stability has likewise grown. Although a reasonable supervision and control program may not foresee every potential failure or prevent every undesirable consequence, in an effort to reduce the future occurrence of such potential issues, FINRA is providing guidance on effective supervision and control practices for member firms and market participants that use algorithmic strategies. These effective practices are focused on five general areas: General Risk Assessment and Response; Software/Code Development and Implementation; Software Testing and System Validation; Trading Systems; and Compliance.
Questions concerning this Notice should be directed to:
Background & Discussion
This Notice is one of seven FINRA initiatives relating to equity market structure and automated trading activities, including HFT.1 These initiatives are designed to increase the scope of trading information FINRA receives, provide more transparency into trading activities to market participants and investors, and require firms engaged in electronic trading and their employees to be trained, educated and accountable for their role in equity trading.
As algorithmic strategies have grown to account for a substantial portion of activity on U.S. securities markets, the potential for such strategies to adversely impact market and firm stability has likewise grown. FINRA member firms that engage in algorithmic strategies are already subject to a number of existing SEC and FINRA rules governing their trading activities, including those listed below, as well as FINRA Rule 3110 (Supervision).2 Thus, many existing requirements address the risks of, and impose obligations on, trading activity conducted by algorithmic strategies.
FINRA has long noted that, in addition to specific requirements imposed on trading activity, firms have a fundamental obligation generally to supervise their trading activity to ensure that the activity does not violate any applicable FINRA rule, provision of the federal securities laws or any rule thereunder.3 This would include, for example, ensuring that the firm's trading activity that uses algorithmic strategies complies with applicable rules and regulations, including:
With the occurrence of a number of market-impacting events related to technology issues in the past several years, the SEC, FINRA, other U.S. and foreign regulators, academics and commentators have focused on the issues of whether the current regulatory framework provides sufficient protection against the occurrence of technology failures by market participants, particularly where the failures can have a systemic impact on our highly automated and interconnected markets, and whether additional steps are necessary to mitigate the risks of the reoccurrence of such events in the future.12 Most recently, the SEC adopted Regulation SCI with the stated intent of strengthening the technological infrastructure of key market participants. Although, as adopted, Regulation SCI applies primarily to self-regulatory organizations and alternative trading systems (ATSs) and not to broker-dealer algorithmic trading activity, the SEC stated that it could in the future seek comment on whether to expand the scope of Regulation SCI to include broker-dealer operations as well.13 The guidance in this Notice regarding firms' responsibilities for their algorithmic strategies is consistent with the SEC's fundamental approach in Regulation SCI of requiring that comprehensive policies and procedures be in place for certain technological systems and mandating the testing and review of those systems.
FINRA staff has conducted a number of examinations and investigations over the past several years that were prompted by the detection of systems-related issues at firms engaged in algorithmic strategies, and several of these investigations have resulted in settlements of formal actions. Among other things, these actions have noted that some firms lack appropriate supervisory controls and procedures related to the creation, modification, usage and testing of trading algorithms for such activity as wash sales and excessive levels of message traffic. As a result of these reviews and working with member firms engaged in algorithmic strategies, FINRA has developed the following list of suggested effective practices for such firms. These effective practices are focused on five main areas: General Risk Assessment and Response; Software/Code Development and Implementation; Software Testing and System Validation; Trading Systems; and Compliance.
As an initial matter, firms must have appropriate policies and procedures in place to review and test any trading algorithms they use, including development, deployment and post-implementation monitoring of algorithmic strategies. Although a reasonable supervision and control program will not foresee every potential failure or prevent every undesirable consequence, this Notice provides a list of effective supervision and control practices for firms that use algorithmic strategies that are based largely on FINRA staff's examination and investigative work related to algorithmic strategies. FINRA believes that firms' implementation of the suggested effective practices may help to reduce the future occurrence of unintended systems issues by firms engaging in algorithmic strategies; however, the list below is not intended to be an exhaustive list of steps firms should consider in conducting such activities. The suggested effective practices are largely drawn from discrete issues FINRA staff identified in connection with specific investigations and examinations. A firm's implementation of these effective practices in and of themselves would not necessarily suffice to satisfy its supervisory and other obligations that may arise under FINRA rules, the rules of other self-regulatory organizations, and SEC rules and regulations. In this regard, the effective practices below complement, rather than supplant, obligations firms have under existing or future rules and regulations, including those noted above.
Suggested Effective Practices for Firms Engaging in Algorithmic Strategies
As noted above, as the use of algorithmic strategies has increased, the potential of such strategies to adversely impact market and firm stability has likewise grown. When assessing the risk the use of algorithmic strategies creates, firms should undertake a holistic review of their trading activity and consider implementing a cross-disciplinary committee to assess and react to the evolving risks associated with algorithmic strategies.14 These committees are most effective when they include representation from areas outside of trading, such as those engaged in support and control types of functions within the firm.
A firm's supervisory efforts should be focused on every stage in the process of developing algorithmic strategies and not be limited to reviewing trading activity by algorithmic strategies only after they have been put into production. Consequently, firms should also focus efforts on the development of algorithmic strategies and on how those strategies are tested and implemented. Firms should consider, for example:
Testing of algorithmic strategies prior to being put into production is an essential component of effective policies and procedures. When developing their policies and procedures around testing and system validations, firms should consider:
A firm's supervisory obligations continue after any algorithmic strategy is put into production. Consequently, firms should develop their policies and procedures to include review of trading activity after an algorithmic strategy is in place or has been changed. Firms should consider:
Ensuring that there is effective communication between compliance staff and the staff responsible for algorithmic strategy development is a key element of effective policies and procedures. To that end, firms should consider:

Wash sales (i.e., trading involving no change in beneficial ownership that is intended to produce the false appearance of trading) continue to be strictly prohibited under both the federal securities laws and FINRA rules. See, e.g., 15 U.S.C. 78i(a)(1); FINRA Rule 6140(b).
5 The term "market access" is defined as access to trading in securities (i) on an exchange or alternative trading system (ATS) as a result of being a member or subscriber of the exchange or ATS or (ii) on an ATS provided by a broker-dealer operator of an ATS to a non-broker-dealer. The term includes not only sponsored access and direct market access, but also includes access to trading for proprietary accounts or more traditional agency trading activities. See 17 CFR 240.15c3-5(a)(1).
6See 17 CFR 240.15c3-5.
7See 17 CFR 242.600 et seq.

10See 17 CFR 242.200 et seq.
11See 17 CFR 242.201(b)(1). The prior day's closing price is determined as of the end of the prior day's regular trading hours on the security's listing market. See 17 CFR 242.201(b)(3).
12 Among the many efforts in this regard are the following. The SEC hosted a roundtable entitled Technology and Trading Roundtable: Promoting Stability in Today's Markets in October 2012, and, in November 2014, the SEC adopted Regulation Systems Compliance and Integrity (Regulation SCI). See Securities Exchange Act Release No. 73639 (November 19, 2014), 79 FR 72252 (December 5, 2014). A transcript of the SEC roundtable is available at http://www. sec.gov/news/otherwebcasts/2012/ttr100212- transcript.pdf. In September 2013, the CFTC approved for publication Concept Release on Risk Controls and System Safeguards for Automated Trading Environments setting forth a series of proposed risk controls for participants in the futures markets. See Commodity Futures Trading Commission Release, 78 FR 56542 (September 12, 2013). The CFTC reopened the comment period for this CFTC Concept Release on January 21, 2014, through February 14, 2014. See Commodity Futures Trading Commission Release, 79 FR 4104 (January 24, 2014). The Federal Reserve Bank of Chicago conducted a survey of how HFT firms control risks. See Carol Clark and Rajeev Ranjan, How Do Proprietary Trading Firms Control the Risks of High Speed Trading? March 2012. A working group has written a proposal for the adoption of an ISO 9000-like standard for firms engaged in HFT. See Ben Van Vliet et al., The Rationale for HFT 9000: An ISO 9000-style Quality Management System for High Frequency Trading, August 2012. In October 2012, the Foresight Programme of the UK Government Office for Science released its final report relating to potential measures to be taken as a consequence of the growth of computerized trading in the financial markets. See Government Office for Science, London, Foresight: The Future of Computer Trading in Financial Markets (2012). The European Securities Markets Association (ESMA) issued guidelines for entities engaged in automated trading. See ESMA, Guidelines on systems and controls in an automated trading environment for trading platforms, investment firms, and competent authorities, December 2011. In November 2010, the FIA Principal Traders Group issued a series of recommendations for risk controls over electronic trading. See FIA Principal Traders Group, Recommendations for Risk Controls for Trading Firms, November 2010.

14 Although cross-disciplinary committees may help firms with their compliance efforts regarding algorithmic strategies, committees should not take the place of oversight of these strategies by appropriately registered personnel of the firm.
15 While the application of these effective practice suggestions may vary greatly across firms, it is generally appropriate to give greater focus to material code portions and system functions.
16 While not an exhaustive list, particular consideration should be given to monitoring for activity such as messaging volume, order looping, and matched or wash trades.
