Mifid data publishers drag feet on Esma guidelines

Four publishers yet to align post-trade data format with Q&A issued eight months ago

Europe’s vast market transparency rules are now more than a year old, but some of the teething troubles have not gone away. Transparency relies on data that was supposed to be provided for free, but some of that data is still inaccessible. Some firms tasked with publishing it are dragging their feet to comply with guidance that was set out more than eight months ago specifically to tackle bad practices. And even where publishers have changed their methods, the data can still be difficult to use.
