257. As regards the definition of the 'Execution timestamp', there are some differences between the CDE guidance and the former RTS on reporting. These differences are due to the fact that the definition under the EU legislation was drafted in order to also apply to ETDs reporting, whereas the CDE definition only refers to OTC contracts. Therefore, in this case, a misalignment with CDE guidance appears justified by the different purposes pursued. ESMA proposed to enrich the definition provided in the CDE guidance in order to address also the reporting at position level. All respondents supported the proposal.
