MiFID II Article 27 evidence retention obligations remain in force for EU + UK-authorised brokers in 2026. For risk-mgmt vendor procurement, the specific audit-trail requirements define the procurement-minimum baseline every vendor must support:
Required evidence retention per Article 27 + adjacent rules:
- Best execution documentation - Internal evidence that client orders were executed at the best available price. For A-book brokers, this means storing FIX execution report data from the LP alongside the MT4/MT5 trade record. For B-book brokers, internal execution venue + pricing documentation.
- Margin call notification timestamps - Timestamped record of every margin call notification sent to the client + the equity level at the time of notification.
- Stop-out event timestamps - Timestamped record of every stop-out event + the equity level at the time of stop-out.
- Position limit + dealer-desk audit trail - Pre-trade + post-trade limit checks + manual dealer intervention logs.
Why this matters for vendor procurement. Operators scaling past a few hundred active clients face reliable audit-trail production as the primary risk-mgmt procurement criterion. Without it:
- Client dispute resolution (margin call timing disputes, stop-out equity disputes) becomes operationally expensive
- CySEC + FCA inspections risk findings on Article 27 non-compliance
- A-book brokers cannot demonstrate best execution to clients or regulators
The vendor procurement framework. The chapter’s six-dimension scorecard should explicitly weight Article 27 compliance under the trust signals dimension. Vendors with documented audit-trail completeness + LP FIX execution storage + margin/stop-out timestamp retention score highest; vendors with proprietary log formats or limited dispute-resolution data structure score lower.
Specific chapter vendor Article 27 readiness:
- Centroid Risk - Documented multi-platform connectivity (MT4/MT5/cTrader/FIX) + real-time data analytics. Audit trail strong for A-book brokers running multi-LP routing.
- oneZero - $250B+ ADV with regulatory reporting partner services. Audit trail mature.
- Brokeree Risk - Multi-server liquidity aggregation + hybrid A-Book/B-Book execution. Audit trail depth requires operator verification.
- PrimeXM - 120+ market makers + tier-1 banks + published pricing. Bridge audit trail strong.
- B2Risk + Leverate Risk + Match-Trade Risk - Bundled with broker CRM = integrated audit trail but stack-specific structure.
- Acuity - Analytics layer not pure risk-mgmt; audit trail responsibility lives with the underlying risk-mgmt vendor.
Operator action items for 2026 H2 procurement.
- Audit current risk-mgmt vendor’s Article 27 compliance documentation. Request the vendor’s response to standard CySEC + FCA inspection questions on margin call + stop-out + best execution data.
- Verify FIX execution report storage for A-book operations - this is the single most common Article 27 compliance gap discovered in CySEC inspections.
- Cross-reference with the FCA Consumer Duty + prime brokerage consolidation dispatch (liquidity PR #93) - FCA Consumer Duty enforcement compounds with Article 27 audit requirements across the broker’s risk stack.
- For multi-jurisdictional operators, verify vendor’s audit trail format supports both EU MiFID II + UK FCA COBS requirements without parallel system deployment.

PFOF ban 30 June 2026: the A-book transition compounds Article 27 requirements
Update — June 2026. The EU PFOF ban under MiFIR Article 39a becomes fully effective 30 June 2026, when Germany’s last Member State temporary exemption expires. Germany was the only EU jurisdiction using the exemption (granted March 2024). For brokers transitioning from B-book or hybrid models to full A-book execution under the PFOF deadline, the Article 27 audit-trail requirements become materially harder to satisfy: every A-book order now requires a FIX execution report from the LP retained alongside the MT4/MT5 trade record, timestamped margin call notifications, and stop-out event logs. Risk-mgmt vendors with LP-native FIX connectivity (Centroid, oneZero, PrimeXM, TFB Trade Processor) are better positioned to support the A-book transition than analytics-only tools. Operators should verify LP FIX execution report storage before June 30.
