Exchange Regulations and the directorial resolutions, while it is the CEO's responsibility to establish CEO-level resolutions. The Exchange Rules contain all binding provisions regarding membership, trading, the listing and continued trading of securities, de-listing of securities as well as sanctions, the publication method of Exchange data, incompatibility and trading floor commercial structures. The Exchange Regulations contain effective rates, the construction of the Exchange's working organisation and its operation and all binding rules for the corporate system of traders, issuers and investors. Directorial and CEO-level resolutions define rights and responsibilities for issuers, traders and brokers. These sources of law enter into effect when the Board of Directors – apart from its own resolutions – ratifies the rule, regulation or CEO-level resolution. When this happens, the CEO states the effective date in his or her resolution .  In the case of regulations, the permission of the Supervisory Authority is also needed for the regulation to enter into force.

Act CXX of 2001 on the Capital Market (hereinafter: CMA) contains rules for the trading of securities, investment managers, investment trusts, the Exchange, the operation of the clearing house and state supervision of all these. The latest modification of the CMA was primarily justified by the implementation of the Markets in Financial Instruments Directive (“MiFID”, No. 2004/39/EC) and Directive 2004/109/EC on the harmonisation of transparency requirements in relation to information about issuers whose securities are admitted to trading on a regulated market (the Transparency Directive) in Hungary. Act CXXXVII of 2007 on the modification of certain acts affecting financial services was developed for the purposes of legal harmonisation because of the same objective. The two major goals of the MiFID were the Community-level standardisation of the rules on investment firms and the activities thereof, and the strengthening of the protection of clients. Effective from 1 December 2007, a separate legal regulation is valid for investment firms and commodity exchange service providers, and the rules for the licensed activities of these (i.e. Act CXXXVIII of 2007).
