Yes. As clarified under Recital 20 of Commission Delegated Regulation (EU) 2017/565, DEA users may be classified as HFTs if they meet the conditions set out under Article 4(1)(40) of MiFID II and Article 19 Commission Delegated Regulation (EU) 2017/565.
In order to assess whether a DEA user meets the applicable message thresholds, firms accessing trading venues through DEA may contact their DEA provider which is obliged to record the data relating to the orders submitted, including modifications and cancellations under Article 21(5) of RTS 6[1].
However, the onus remains on investment firms to ensure that the estimates provided by the DEA providers accurately reflect their actual trading activity (and in particular that it only takes into account proprietary trading activity on liquid instruments excluding, in the case of DEA users sub-delegating the DEA provider’s code, messages sent by their own DEA clients).
