Market Surveillance Systems Testing – Alerts Testing Marking The Close Front Running Wash Trading Spoofing Layering One of the main purposes of Market Surveillance systems is the prevention and investigation of abusive, manipulative or illegal trading behaviour in the markets. There are a set of pre-configured patterns with known abusive behavior that help streamline regulatory compliance in this area. Market Surveillance systems also contain modules that allow users to create new patterns – or adjust the existent ones – and integrate them into the system. Exactpro has tested a number of Market Surveillance Systems across different markets and locations. Our expertise spans: ● Building and maintenance of test/regression libraries covering system platforms E2E; ● Automating the testing process using proven tools and methodologies; ● Building up a holistic approach encompassing the full cycle of Market Surveillance Systems Testing based on our experience of testing the world’s leading Trading, Exchange and Clearing platforms.

exactpro.com 20 BUILD SOFTWARE TO TEST SOFTWARE What is Software? Software can be understood as a collection of instructions and data that direct a computer’s operation. These instructions frequently include control-flow constructs that evaluate incoming data: if the data is accepted, the system’s internal state is modified; if the data is rejected, the state remains unchanged. Unlike human decision-making, these checks are executed automatically and at scale – there is no human in the loop processing each conditional branch. Instead, the programmer encodes policies and rules once, and the machine applies them consistently and tirelessly. At a more fundamental level, software itself is data. The same sequences of bits that represent program instructions can be stored, transmitted and manipulated just like any other data. This equivalence – central to the stored-program computer model – allows programs to process other programs, to be compiled, interpreted or even rewritten dynamically. Thus, software is both instructions for action and data for manipulation, embodying automated decision-making that operates without continuous human oversight.

exactpro.com 24 BUILD SOFTWARE TO TEST SOFTWARE Natural and Artificial Intelligence Dichotomy Intelligence is the capability to acquire, process and apply knowledge and skills. Humans: ● Humans have intelligence – though we do not yet know what it truly is. ● They interact with reality through skills. ● They hold knowledge in their minds, in the form of ideas. ● They can learn, generalise, isolate and abstract. ● They can convert ideas ↔ artifacts in a continuous cycle. ● Their interactions with reality and with artifacts serve as a proxy for understanding human intelligence. Software: ● Running software executes a set of instructions. ● It can process data and produce synthetic artifacts. ● It interacts with reality through data flows and control loops defined in its instructions. ● Its interactions with reality can be represented as data. ● Artificial intelligence is software capable of acquiring, processing and applying knowledge and skills. ● Synthetic artifacts provide a proxy for exploring artificial intelligence.

exactpro.com 27 BUILD SOFTWARE TO TEST SOFTWARE The Compliance Burden in Financial Technology ● Regulatory complexity: standards and laws governing regulatory compliance in the financial space continuously evolve across jurisdictions; rules and requirements may overlap or simply be highly extensive in coverage and numbers of articles. ● Financial institutions operate within a complex regulatory environment where legal obligations, risk controls, technology requirements and compliance processes are deeply interconnected. ● Regulation is becoming increasingly difficult to track manually, so leveraging AI in the compliance function presents a valuable automation use case. ● If introduced correctly and with sufficient guardrails, AI can help significantly streamline the effort spent on updating and maintaining regulatory texts. It can also transform the legal corpora from static text into dynamic data-driven system with executable controls.

exactpro.com 28 BUILD SOFTWARE TO TEST SOFTWARE The Regulatory Compliance Landscape in Financial Organisations For financial market infrastructures, regulatory compliance depends on the ability to align rule books, operational controls, technology platforms and testing activities. AI-driven automation can help organisations establish end-to-end traceability across the software lifecycle, improve coverage visibility and streamline compliance reporting under increasing regulatory scrutiny. Financial regulations rarely say: "Develop software using Java." or “Provision for 5 times the average daily capacity.” Instead they state requirements such as: “Systems must be resilient; transactions must be traceable; customer data must remain confidential; access must be controlled; incidents must be reported; records must be retained.” Legal texts intentionally use generic language to accommodate a wide variety of situations and technology implementations. Each article may also cover many overlapping areas in which a trading venue is subject to regulatory compliance. These legal obligations need to be continuously interpreted and translated into software and the surrounding processes, for to be maintained. 

exactpro.com 29 BUILD SOFTWARE TO TEST SOFTWARE Human – “I know It When I See It” The most famous opinion from the case is Justice Potter Stewart's concurrence, stating that the Constitution protected all obscenity except "hard-core pornography". He wrote, "I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that”.

exactpro.com 31 BUILD SOFTWARE TO TEST SOFTWARE Legacy View on Regulatory Compliance Historically, regulatory compliance has been viewed as a legal and organisational function. The workflow is typically: Regulation Lawers Compliance Officers Policies Manual Controls Audits Technology appears only near the end of the chain. As a result: ● regulations become Word documents ● policies become PDFs ● controls become spreadsheets ● testing becomes manual evidence gathering ● audits become expensive reconstruction exercises The software implementing the business often has only a weak connection to the regulatory obligations that motivated it. 

exactpro.com 32 BUILD SOFTWARE TO TEST SOFTWARE Legacy View on Regulatory Compliance Today's financial institutions are software companies that happen to provide financial services. Every regulated activity is ultimately performed by software: ● payments ● trading ● clearing ● settlement ● custody ● lending ● onboarding ● surveillance ● reporting Therefore every regulatory obligation eventually becomes software behaviour. The real question is no longer "Are we compliant?", but "Does our software always behave in a manner consistent with applicable regulation?" 

exactpro.com 33 BUILD SOFTWARE TO TEST SOFTWARE Legacy View on Regulatory Compliance Regulatory Concept Software Equivalent Obligation Requirement Exception Alternative flow Prohibition Validation rule Time limit Timeout / scheduler Threshold Configuration parameter Approval Workflow state Evidence Log / event / document Record retention Data lifecycle policy Segregation of duties Access control Continuous monitoring Runtime verification Almost every regulatory requirement can be decomposed into software concepts. Viewed this way, regulation is no longer mysterious. It is simply another specification that software must satisfy. 

exactpro.com 34 BUILD SOFTWARE TO TEST SOFTWARE Compliance Architecture is Software Architecture The institution does not become compliant because it owns policies. It becomes compliant because thousands of software decisions collectively implement those policies. Examples include: ● workflow design ● access control ● state transitions ● data models ● audit logging ● configuration management ● exception handling ● deployment controls Every architecture decision may have regulatory implications. 

exactpro.com 35 BUILD SOFTWARE TO TEST SOFTWARE Compliance Defects are Software Defects This perspective also changes how defects are viewed. Examples include: ● missing audit events ● incorrect permission checks ● inaccurate calculations ● broken approval workflows ● incorrect data retention ● reporting inconsistencies ● incomplete customer screening ● race conditions creating temporary violations Many compliance failures originate not from misunderstood regulation but from ordinary software bugs.

exactpro.com 36 BUILD SOFTWARE TO TEST SOFTWARE Compliance is a Living System Regulations evolve. Products evolve. Software evolves. Therefore, compliance cannot be a one-time certification exercise. Instead it becomes continuous engineering that should include: ● response quality ● hallucination rates ● latency ● user feedback ● security incidents ● regulatory changes If a regulation changes tomorrow, the AI knowledge base should be updated, and previous responses may need revalidation.

exactpro.com 38 BUILD SOFTWARE TO TEST SOFTWARE Compliance by Design Build compliance into the system, not around it Usual approach ● Software is developed first. ● Compliance is assessed later through reviews, controls and audits. ● Gaps are identified after implementation, leading to costly remediation and increased operational risk. Recommended practice ● Regulatory obligations are considered from the outset. ● Compliance requirements are translated into system requirements, business rules and architecture decisions. ● Controls, auditability and evidence generation are embedded directly into the software.

This “completeness” is measured only relative to a specific population of possible test cases, such as lines of code, branches, n-length sub-paths, predicates, etc. Even if you achieve complete coverage for a given population of tests (such as, all lines of code tested), you have not done complete, or even adequate, testing. “We can and should expand the list of populations of possible test cases. We can measure coverage against each of these populations. The decision as to whether to try for 1%, 10%, 50% or 100% coverage against any given population is non-obvious. It involves trade-offs based on thoughtful judgment.” – Cem Kaner, J.D., Ph.D., ‘Software Negligence and Testing Coverage,’ 1995. 

exactpro.com 51 BUILD SOFTWARE TO TEST SOFTWARE Software Negligence and Testing Coverage “This appendix lists 101 coverage measures. Coverage measures the amount of testing done of a certain type. Because testing is done to find bugs, coverage is also a measure of your effort to detect a certain class of potential errors. For example, 100% line coverage doesn’t just mean that you’ve executed every line of code; it also means that you’ve tested for every bug that can be revealed by simple execution of a line of code.” – Cem Kaner, J.D., Ph.D. Fig. 5 Excerpt from the 101 coverage measures list put together by Cem Kaner

exactpro.com 57 BUILD SOFTWARE TO TEST SOFTWARE Key Features that Simplify Adoption of the Framework The SUT (System Under Test) domain model is based on posterior traffic data analysis that makes developing the model substantially simpler in comparison to full-scale digital twins implemented in Python or OCaml. Simplification allows to quickly migrate the domain model to a different language using AI-coding assistants and enables software testers to maintain the code of the model themselves. A clear separation between scenario generation, execution and output interpretation make the acceptance framework agnostic to the way test scenarios/execution logs were produced, allowing to ingest the data generated by the existing test libraries and tools. LLM-based code assistants are only used during verification rules development. Users have full control over the snippets of data/code that are provided to the foundation models. Only deterministic code is used during test results analysis. No external API access is required. Software testers and LLMs sometimes produce incomplete or even erroneous rule verification code. The key idea of the acceptance framework is to make it easier for the users to detect and debug such situations using a dedicated user interface integrated with the code assistant tools of their choice.
