Market Surveillance ensures proper conduct of trading

The Market Surveillance ensures proper conduct of trading and that the determination of prices corresponds to the prevailing market situation on the stock exchange. Various institutions work closely together here. The aim of Market Surveillance is to protect investors and to create confidence in the market mechanisms.

The TSO monitors trading

The Trading Surveillance Office (Handelsüberwachungsstelle, henceforth referred to as ‘TSO’) is an independent exchange body and performs and is responsible for trading surveillance. The TSO monitors trading on the Frankfurt Stock Exchange (Xetra® as well as the Specialist-supported trading) including the derivatives exchange Eurex Deutschland. The TSO investigates irregularities and notifies the management boards of the stock exchanges as well as the Exchange Supervisory Authority (Börsenaufsichtsbehörde) of the results of its investigations. It also forwards cases to the Federal Financial Supervisory Authority (BaFin), in case these fall within its area of responsibility.

As far as general questions about trading on the Frankfurt Stock Exchange and Eurex Deutschland are concerned, the staff of the Investor Center will be available by email at or you may call +49 69 21118310. 

We kindly request you to direct any questions regarding specific orders or transactions to your order-executing bank as the direct exchange participant which might involve the respective exchange or the TSO for their response.

You may also inform the TSO on potential violations of the rules (in particular market abuse and insider trading) by email to (for the Frankfurt Stock Exchange) or to (for Eurex Deutschland). In this context, please be advised that the TSO is obliged to maintain confidentiality in accordance with the Exchange Act and the Market Abuse Regulation and is not permitted to inform the whistleblower on the results of their investigation.
