European Rules for Algorithmic Trading: MiFID II, MiFIR, and MAR
Summary
This overview explains how European Union financial regulation applies to algorithmic trading. It describes ESMA’s role in setting standards and the role of national regulators in implementing and supervising them. It introduces MiFID II as a framework covering such areas as market transparency, investor protection, automated trading controls, transaction records, clock synchronization, and circuit breakers. MiFIR is presented as addressing transparency, reporting, derivatives, clearing access, and supervisory measures, while MAR covers insider dealing, unlawful disclosure of inside information, and market manipulation.
The article highlights additional MiFID II provisions relevant to high-frequency trading, firms using algorithms, and individuals active in commodity derivatives, including systems resilience and position controls. Its practical method is to identify the participant’s role and activity, then consult the applicable directive, regulation, and guidelines. The text is an introductory orientation, not a compliance checklist or legal opinion. It contains incomplete passages and may not reflect later legal or regulatory changes, so readers should verify current requirements with authoritative sources and qualified advisers.
