(8)Trading venues, approved publication arrangements (APAs) and investment firms do not interpret the requirements related to the disclosure of post-trade transparency information to the public and the information to be provided to the European Securities and Markets Authority (ESMA) and competent authorities for the purpose of the transparency calculations consistently. As a result, such information is incomplete, inaccurate or inconsistent. This undermines the usability of such information and the quality and accuracy of the transparency calculations based on the submitted data. To promote the consistent application of the post-trade transparency requirements across the Union, it is therefore necessary to further specify the content of the data requests, and in particular the details to be disclosed by trading venues, APAs and consolidated tape providers when they report reference data and quantitative data to ESMA and competent authorities.
