Terms of Service — AntiOverfit Audit Document version: 1.0 Effective date: 15/04/2026 Service provider: Enrique Enguix 1. Purpose These Terms of Service govern the purchase and use of AntiOverfit Audit, an external robustness audit service for MetaTrader 5 Expert Advisors. AntiOverfit PRO is the technical engine used to perform the process. AntiOverfit Audit is the commercial service offered to the client. The purpose of the audit is to measure, under a defined methodology, the extent to which a specific version of an Expert Advisor depends on a specific historical path, by comparing its behavior on the base historical series against multiple plausible synthetic market paths generated under the AntiOverfit technical framework. The audit does not certify future profitability, does not constitute investment advice, does not guarantee operational or commercial safety, and does not replace the independent due diligence of buyers, sellers, or end users. 2. Acceptance By requesting the service, making payment, or sending materials for the audit, the client accepts these Terms of Service in full, together with the official AntiOverfit Audit documentation in force at the time of the engagement, including its publication rules, versioning rules, badge rules, and the technical standard applicable on the audit date. 3. Definitions For purposes of these Terms: * Service: AntiOverfit Audit. * Technical engine: AntiOverfit PRO, in the frozen version applicable to the current official standard. * Client: the individual or legal entity requesting the audit. * EA: the Expert Advisor being audited. * Audited version: the exact EA version submitted by the client and frozen for the audit. * Badge: the official AntiOverfit Audited visual asset issued for a specific audit. * Audit Promo Card: the official promotional visual asset prepared for use in Market listings, websites, or the client’s materials. * Audit ID: the document reference identifier assigned by AntiOverfit to a specific audit. * Result: the score, grade, written interpretation, publication status, and related materials issued under the audit. * Material change: any relevant modification to logic, money management, filters, default parameters, or other elements capable of materially affecting the EA’s behavior. * Reaudit: a new audit requested for a new version, a new historical window, a new standard, or to replace a previous result. * Non-Standard Audit: any audit that departs from the official standard in force. 4. Nature and scope of the service 4.1. AntiOverfit Audit is an external robustness audit service. Its purpose is to issue a technical result under a defined and repeatable methodology. 4.2. The service evaluates structural robustness under plausible market path variation. It does not evaluate or promise future profits. 4.3. Unless expressly agreed in writing, the service does not include: * optimization of the client’s EA, * trading or investment advice, * legal or regulatory validation of the product, * source code review, * commercial compatibility guarantees within the MQL5 ecosystem, * ongoing technical support after the audit result is issued, * multi-version, multi-symbol, or multi-broker audits beyond the agreed scope. 4.4. Unless expressly stated otherwise in writing, each audit is issued for one exact version, one audited base symbol, one specific standard, and one specific audit date. 5. Applicable technical standard 5.1. Every standard audit will be performed under the official AntiOverfit Audit standard in force on the date the engagement is accepted. 5.2. Unless a Non-Standard Audit is expressly contracted, the client accepts that AntiOverfit may use a fixed technical environment, including, depending on the standard in force: * frozen AntiOverfit PRO engine version, * reference broker, * backtest timeframe, * historical window length, * official historical window update dates, * target number of synthetic worlds, * world validation rules, * formulas, weights, thresholds, and public scoring scale. 5.3. The client acknowledges that audit results are only rigorously comparable when interpreted within the exact standard under which they were issued. 6. Eligibility requirements and client materials 6.1. To request an audit, the client must provide at minimum: * product name, * exact EA version, * compiled executable file or another executable access method accepted by AntiOverfit, * default set file or audit-specific set file, * installation notes or required dependencies, * requested audit symbol, where applicable, * known execution restrictions, * written confirmation that the submitted version matches the commercial version the client wishes to promote. 6.2. AntiOverfit may reject or pause an audit if: * the submitted materials are incomplete, * the EA does not execute correctly, * the client cannot demonstrate sufficient control over the product, * dependencies are undocumented, * the environment does not allow reasonably verifiable execution, * the product changes during the process, * or the intended use of the result is incompatible with these Terms. 6.3. The client is responsible for ensuring that all submitted materials are functional, lawful, and sufficient for the audit. 7. Handling of EX5 files, set files, and submitted materials 7.1. The client retains ownership of its EA, set files, documentation, and any other proprietary materials. 7.2. The client grants AntiOverfit a limited, non-exclusive license, revocable only with respect to work not yet performed, solely for the time and scope necessary to: * install, * execute, * test, * audit, * document, * archive internally, * and, where applicable, publish the audit result under the rules of the service. 7.3. AntiOverfit does not acquire ownership of the EX5, set files, or the client’s commercial logic by providing the service. 7.4. AntiOverfit will not perform reverse engineering of the EX5 beyond what is strictly implicit in its functional execution within the audit environment. 7.5. Unless required by law, operational necessity, or the client’s express authorization, AntiOverfit will not publish the EX5 file, private set files, or sensitive information that is not necessary to describe the result. 7.6. AntiOverfit may retain materials and audit evidence internally for a period of 90 days for traceability, recordkeeping, quality control, documentary defense, and the management of future reaudits. 8. Confidentiality 8.1. AntiOverfit will treat as confidential any non-public information provided by the client that should reasonably be understood as confidential, including executables, non-public set files, technical notes, and materials not intended for publication. 8.2. The confidentiality obligation does not apply to information that: * is already public without breach of these Terms, * was already lawfully in AntiOverfit’s possession, * must be disclosed by law or valid order of a competent authority, * is expressly authorized by the client for publication, * or is necessary to publish a valid promotional result under the official service rules. 8.3. The client authorizes the publication of the minimum factual result data where publication is valid under the service rules, including product name, audited version, score, grade, audited base symbol, audit date, Audit ID, and associated promotional assets. 9. Result, score, and limits of interpretation 9.1. Every result issued by AntiOverfit Audit refers exclusively to the specific framework under which it was produced. 9.2. The client acknowledges that the score, grade, and written interpretation: * are not a guarantee of future performance, * do not constitute investment advice, * do not certify absolute technical safety, * do not ensure equivalent live trading behavior, * and do not replace the independent judgment of third parties. 9.3. The system’s official short legal phrase may accompany the result and must be preserved whenever it forms part of the badge or Audit Promo Card: External robustness audit. Not a promise of future results. 10. Publication and visibility of the result 10.1. All clients receive their result and the documentation included in the purchased package. 10.2. Only results that are publishable under the current official public layer of the system may be published by AntiOverfit. 10.3. Unless the official standard changes in the future, the current public rule is: * publishable results: publication allowed, * non-publishable results: private delivery only. 10.4. AntiOverfit will determine the format of public publication, including channel, blog, promotional cards, visual assets, and descriptive text, while preserving the factual integrity of the result. 10.5. The client may not require public publication when the result does not meet the official publication conditions. 11. Badge, Audit Promo Card, and promotional usage rights 11.1. Where included in the purchased package and once a result has been issued, AntiOverfit may provide an official badge, an Audit Promo Card, or other promotional assets related to the result. 11.2. The client receives a limited, non-exclusive, non-sublicensable unless expressly authorized, and revocable right to use those assets only in connection with: * the exact audited version, * the exact issued result, * and communications compatible with these Terms. 11.3. The following are prohibited: * materially altering the badge or card, * editing the score, grade, Audit ID, date, audited symbol, or exact version, * removing the legal phrase when it forms part of the asset, * reusing the asset for a materially modified version, * presenting the audit as a guarantee of future results, * suggesting that AntiOverfit commercially endorses the product beyond the issued result, * using the result in a misleading, incomplete, or out-of-context way. 11.4. AntiOverfit may require removal or correction of promotional use if it detects misleading, decontextualized, or non-compliant use of the result. 12. Version rule and definition of material change 12.1. Every audit belongs to an exact EA version. It does not belong to the product in the abstract. 12.2. Without limitation, a material change includes any relevant modification to: * entry or exit logic, * money management, * filters, * risk management rules, * default parameters, * trading frequency, * session, symbol, or condition dependencies, * auxiliary modules that alter behavior, * or any other element that could reasonably change the robustness result. 12.3. The responsibility to disclose material changes lies with the client. 12.4. AntiOverfit reserves the right to determine that a version has materially changed even if the client has not explicitly declared it, where there are reasonable grounds to do so. 13. Reaudit 13.1. A reaudit will be required when: * the EA version changes materially, * the client requests a new official result, * the applicable standard changes, * the official historical window changes and the client wants an updated result, * the client requests replacement or renewal of a previous result, * or AntiOverfit determines that continued promotional use of the previous result is no longer appropriate. 13.2. Every reaudit may generate a new Audit ID, a new result, and new promotional assets. 13.3. The existence of a previous audit does not oblige AntiOverfit to keep an older publication live if a newer audit supersedes it. 13.4. A reaudit is a new service unless the purchased package expressly includes a minor update within a defined window. 14. Corrections and factual review 14.1. The client will have 3 days from delivery to request corrections strictly limited to verifiable factual errors, including: * product name, * version, * audited symbol, * date, * Audit ID, * transcription mistakes, * clear formal defects in the delivered assets. 14.2. The following do not qualify as factual corrections: * disagreement with the score, * disagreement with the grade, * disagreement with the official methodology, * requests for a different commercial interpretation of the result, * replacement of the EA or set files after execution, * later changes to the product. 14.3. Any request involving a new execution, new version, new set file, or different framework will be treated as a reaudit or an additional service. 15. Delivery times 15.1. Any delivery timeframe indicated by AntiOverfit is a reasonable estimate and not an absolute guarantee unless expressly agreed in writing. 15.2. The delivery clock begins when AntiOverfit confirms that complete and execution-ready materials have been received. 15.3. AntiOverfit may pause the timeline in the event of issues attributable to the client, missing materials, pending clarifications, product execution errors, or scope changes. 16. Pricing, payment, and refunds 16.1. The price of the service will be the one stated in the accepted offer or in the public pricing applicable on the date of contracting. 16.2. Unless otherwise stated, the service may require full payment in advance or a non-refundable booking payment of [AMOUNT / %] before work begins. 16.3. Once preparation, execution, or review of the audit has started, no refund will be due merely because the client is dissatisfied with the score, the grade, the publication outcome, or the commercial reading of the result. 16.4. A full or partial refund may be considered only where: * AntiOverfit expressly agrees not to start the service, * AntiOverfit is unable to perform the audit for reasons exclusively attributable to AntiOverfit, * or a specific written commercial agreement provides otherwise. 16.5. If execution becomes impossible because of defective materials, undeclared dependencies, client changes, withdrawal after work has begun, or incompatibilities attributable to the submitted product, AntiOverfit may retain all or part of the amounts paid in proportion to the work already performed. 17. Non-Standard Audits and scope changes 17.1. Any departure from the official standard will be classified as a Non-Standard Audit. 17.2. Non-Standard Audits may require different pricing, timelines, disclaimers, and publication rules. 17.3. AntiOverfit may reject Non-Standard Audit requests where they would compromise comparability, traceability, or public clarity of the system. 18. Suspension, rejection, or termination 18.1. AntiOverfit may reject, suspend, or terminate an engagement if: * it detects fraud, concealment, or misleading information, * the client uses or intends to use the result in a way incompatible with these Terms, * the client fails to cooperate reasonably, * execution is not feasible with the submitted materials, * unacceptable technical, reputational, or legal risks arise, * or force majeure events occur. 18.2. In such cases, AntiOverfit may determine whether any refund is total, partial, or unavailable depending on the stage of the work and the cause of the termination. 19. Limitation of liability 19.1. To the maximum extent permitted by applicable law, AntiOverfit shall not be liable for: * trading losses, * lost profits, * loss of opportunity, * indirect reputational harm, * indirect or consequential damages, * commercial, investment, or marketing decisions taken by the client or third parties based on the result, * incompatibilities between the audit and later changes to the product, * misuse of the result by the client or third parties. 19.2. AntiOverfit’s total aggregate liability arising from a specific engagement shall be limited, at most, to the amount actually paid by the client for that engagement, except in cases of fraud or other liability that cannot be limited under applicable law. 20. Client representations and warranties The client represents and warrants that: * it has sufficient rights to submit the EA and related materials, * the use of such materials for the audit does not infringe third-party rights, * the submitted version is the version the client wishes to audit and, where applicable, promote, * the information supplied is materially accurate, * and the client will not use the result in a misleading manner or in breach of these Terms. 21. Changes to the service and to these Terms 21.1. AntiOverfit may update these Terms of Service for future engagements. 21.2. Unless expressly stated otherwise, the version applicable to a specific audit will be the version accepted at the start of that engagement. 21.3. Future changes will not retroactively alter a previously issued result, although they may affect future reaudits or future rules of the system. 22. Governing law and jurisdiction These Terms of Service shall be governed by the laws of Spain. Any dispute arising out of or in connection with these Terms or the service shall be submitted, unless mandatory law provides otherwise, to the courts of [CITY / JURISDICTION]. 23.
