[ESMA 70-872942901-38 MiFID II MiFIR market structures Q&A, Q&A 3.17]

The primary purpose of flagging as required under Article 3(2)(a) of RTS 24 is to enable efficient detection of market manipulation by distinguishing the order flow from an investment firm based on pre-determined terms established by the issuer or the trading venue from the order flow of the investment firm acting at its own discretion (see Recital 6 of RTS 24).

ESMA therefore expects that only those orders submitted to a trading venue as part of a market making strategy subsequent to the conclusion of a market making agreement with the relevant trading venue should be flagged as such in field 8 as designated in Table 2 of the Annex of RTS 24. The same applies to field 3 of Table 3 of Annex II of RTS 6.
