and carried out the activity before 28 March 2024 from the prohibition until 30 June 2026, Germany is the only member state that has made use of this discretion. However, these payments must still comply with inducement requirements. This prohibition is expected to enhance market quality by improving execution for retail inves - tors and increasing pre-trade transparency on execution platforms for retail orders. Crypto-Asset Services Like under the revised investment services framework, crypto-asset service providers under MiCA are prohibited from receiving any monetary or non-monetary benefits for routing client orders to any particular trading platform for crypto-assets or any other crypto-asset ser - vice providers. 6.8 Market Integrity Principles Market integrity and market abuse principles are outlined in MAR and complemented by MAD (Directive 2014/57/EU) and delegating and implementing acts, while MiCA and Commission delegated regulation directly addresses crypto- assets. The objective is to ensure EU financial market integrity and investor protection, prohibiting unlawful behaviour. Three types of market abuse practices are banned: insider dealing, unlaw - ful disclosure of inside information and market manipulation.

For HFT, an authorisation from the CNB is always required. Investment firms and regulated entities using AT and HFT must have effective systems and risk controls to ensure market resilience and prevent abuse. Business continuity arrangements, sys - tem testing and monitoring are required. HFT is also subject to other specific requirements (eg, record-keeping or incorporation of “kill switch” ). Use of these technologies requires notification to the competent authorities. 7.2 Requirement to Be Licensed or Otherwise Register as Market Makers When Functioning in a Principal Capacity A person engaged in AT trading for their own account does not need to be authorised as a market maker unless they are using a market- making strategy. This involves, inter alia, posting a firm, simultaneous bid and offer prices of com - parable size and at competitive prices relating to one or more “financial instruments” on one or
