Berlin Stock Exchange Supervisory Authority - File a complaint

The Exchange Supervisory Authority examines matters relating to the two stock exchanges in Berlin or to itself. In doing so, it generally examines whether there has been a violation of stock exchange law.

As a person concerned, you would like to complain about irregularities in transactions on the two stock exchanges in Berlin - Börse Berlin and Tradegate Exchange? You have received an e-mail from an exchange supervisory authority that seems dubious to you? Then you can contact the Berlin Stock Exchange Supervisory Authority with a complaint. The Exchange Supervisory Authority can, for example, inform you whether it is the sender of an e-mail.

The Exchange Supervisory Authority can check whether the legal requirements have been complied with at one of the stock exchanges in Berlin. In doing so, it acts "exclusively in the public interest", i.e. the complaint does not replace legal action (lawsuit). The Exchange Supervisory Authority can provide general information, but does not give individual legal advice like a lawyer.

  1. You submit your complaint in text form to the Berlin Stock Exchange Supervisory Authority. In doing so, you should specifically list the transactions or facts objected to. You can use the online form for this purpose.
  2. If you have not been able to clarify the matter with the Trading Surveillance Office of the respective exchange (see "More information"), your complaint will be examined to determine whether the exchange rules and regulations applicable at the exchange in question have been complied with (legal supervision) and whether trading and the settlement of transactions have been carried out properly (market supervision). If you have received a suspicious email, we will check whether it originated from us.
  3. You will receive a final notice from the Market Surveillance regarding your complaint.
