Quality of Trading

Monitored Trading

Both, trading on Xontro and trading on the fully electronic trading system Equiduct are continuously monitored. The following official institutions ensure fair and orderly trading.

Monitored Trading

Trade Surveillance (Hüst)

German exchange law stipulates that each exchange must have a trade surveillance (HÜST) as an independent exchange organ. The trade surveillance gathers and analyses all data produced during exchange trading and monitors the price fixing through lead brokers. Furthermore the HÜST controls the market participants’ compliance to the exchange rules and regulations and carries out investigations if a market participant has violated the rules. The HÜST is the first point of contact if investors suspect irregularities in their executions. You can reach the HÜST during trading hours (from 8:00 - 22:00 CET) by email (handelsueberwachung@boerse-berlin.de).

The Exchange Supervisory Authority

Börse Berlin is supervised by the competent federal state authority of the City of Berlin – the Exchange Supervisory Authority. In Germany Exchange Supervisory Authorities are generally part of the Economy or Finance ministries or the Senate Administrations of the federal states. The competences of the Exchange Supervisory Authority range from the authorisation of an exchange (or the closing of it) to the supervision of correct trade procedures and exchange transactions and the securing of the adherence to exchange related rules and regulations. In Berlin the Exchange Supervisory Authority is part of the Senate for Economy, Technology and Research.

The Federal Financial Supervisory Authority (BaFin)

The Exchange Supervisory Authority is a part of the financial services supervisory authority. In Germany supervision of the financial services sector is carried out by the Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht (BaFin)). BaFin supervises all areas of the financial industry. It is in turn subject to supervision by the Federal Ministry of Finance.

BaFin’s central tasks in the area of supervision of securities are the combating of insider dealings and market manipulations. All security transactions in Germany need to be reported to BaFin. BaFin staff members analyse trade proceedings using the reported data. BaFin also examines the contents of ad-hoc and director dealing notices and their impact on the price development. If a suspicion arises, that insider trading might have taken place, an official investigation is launched.
