EU Market Abuse Regulation for Java Enterprise Market Surveillance Controls

Use this Skill to review Java enterprise applications, trading systems, order-management services, transaction-monitoring pipelines, market-data platforms, surveillance services, disclosure workflows, insider-list tooling, alert triage applications, investigation records, CI/CD workflows, or operational tooling that may support Market Abuse Regulation (MAR) concerns.

Apply this Skill to determine what engineering controls, reviewable evidence, and escalation paths are needed before a system is released, connected to production trading data, used for suspicious order or transaction monitoring, used to manage inside information, or used to support market-surveillance decisions.

This Skill is not legal advice. It helps Java engineers, architects, tech leads, platform teams, market-surveillance teams, compliance engineering teams, and reviewers identify when MAR concerns may apply and how to translate market-integrity expectations into enterprise architecture controls such as suspicious order and transaction monitoring, insider dealing controls, market manipulation signals, inside-information disclosure evidence, insider-list workflows, alert explainability, model and rule provenance, reviewer decision trails, false-positive handling, investigation records, observability, change control, documentation, and compliance evidence handoff.

The purpose of this Skill is to increase awareness of potential gaps in the system and create engineering evidence for qualified review. The response produced by this Skill does not represent legal advice, a legal opinion, a determination of insider dealing, market manipulation, unlawful disclosure, reportability, jurisdiction, or a final regulatory determination.

The main question is:

When does a Java enterprise financial system require MAR-aware market-surveillance controls, and what should developers build differently?
