Commission Delegated Regulation (EU) 2026/392 of 20 February 2026 amending the regulatory technical standards laid down in Delegated Regulation (EU) 2017/577 as regards the volume cap and the provision of information for the purposes of transparency and other calculations

Amends Delegated Regulation 2017/577 to reflect the 2024 MiFIR/MiFID II review: removes data reporting for the old quantitative SI tests and the volume cap (now calculated from transaction reports), requires XML for scheduled data and direct reporting to ESMA for the derivatives trading obligation, lets authorities set formats for ad hoc requests and extends record retention to five years.
