What MAR and MiFID II require
The EU Market Abuse Regulation (MAR) and MiFID II set the core market conduct rules for firms operating in European markets. Operational obligations typically include:
-
Insider list management for inside-information events, in prescribed format with precise timestamps
-
Suspicious Transaction and Order Reports (STORs) to competent authorities
-
Personal account dealing controls for persons discharging managerial responsibilities and persons closely associated
-
Market soundings records under MAR Article 11
-
Transaction surveillance and communications review
-
Record retention for competent authority review
UK firms operate under equivalent UK MAR and FCA COBS / SYSC regimes with substantially similar operational expectations.
Where firms typically struggle
-
Insider list precision and timing
-
STOR quality driven by surveillance alert quality
-
Personal account dealing rules applied correctly as roles change
-
Cross-border consistency across EU/UK/US/APAC connected operations
-
Evidence assembly for STOR investigations across trade, communications, insider list, and employee data
How MCO supports MAR and MiFID II compliance
MyComplianceOffice (MCO) covers market abuse regime operational workflows through the Know Your Transactions (KYT®) and Know Your Employee (KYE®) suites on one shared platform.
Insider & MNPI Management
MCO's Insider & MNPI Management module enables firms to "create and access insider lists while protecting material non-public information (MNPI) in compliance with securities laws and regulations."
Deal Review Manager
Deal Review Manager addresses "restricted trading, market manipulation, insider trading, customer suitability, fund mandate, anti-money laundering and other conflict scenarios."
Trade Surveillance
Trade Surveillance provides "automation that monitors trade surveillance and customer suitability programs. Easily verify and validate with external market data."
Communications review
eComms Archive and eComms Review in the KYE suite capture and review employee communications. Because KYE and KYT share the same platform, communications tied to surveillance cases surface in the same investigation workspace.
Personal account dealing
The Personal Trading Compliance module in KYE covers personal account dealing workflows for access persons and persons discharging managerial responsibilities.

When MCO is the right choice for MAR and MiFID II
-
The firm operates in EU or UK markets with MAR/MiFID II obligations
-
Insider list management, trade surveillance, communications review, and personal account dealing need to sit on connected infrastructure
-
Global operations require connected market conduct controls across EU/UK, US, APAC, and GCC jurisdictions
-
Competent authority reviews require consolidated evidence from a single system of record
