Violation of the requirements regarding access to the Exchange System
The Sanctions Commission has imposed a fine of CHF 100'000 on participant X with
decision from 12 March 2020 since employees of Company X not registered with SIX Swiss
Exchange made entries in the Exchange System. X failed to ensure, that personal Trader
IDs were only given to other SIX registered traders and, furthermore, failed to ensure the
traceability of proxies during calendar years 2017, 2018 and 2019.
The Audit Report 2018 of participant X revealed irregularities with regard to its access to the
Exchange System of SIX Swiss Exchange as well as its practice regarding trader substitutions.
The subsequent investigation by the Surveillance & Enforcement unit of SIX Exchange
Regulation AG brought to light that X's trading system used to have shareable sessions
operated by a trading desk, where traders at X had access to SIX Swiss Exchange and traders
could submit orders independently by using the same order session/credentials irrespective of
their individual SIX Swiss Exchange registration. X also confirmed that it did not keep records
that can conclusively determine which individuals were operating the automated/algorithmic
systems on a particular data/time, and that next to this there were no procedures in place for
traders to give their trader ID to other registered traders for purposes of proxy and to trace
proxies.
The Sanctions Commission considered, that consistent compliance with the rules for registering
traders as well as traceability is essential, since it is the only way to ensure unequivocal
accountability for entries made in the exchange system and that the identification of the person
responsible for trades is an indispensable prerequisite for trade surveillance and, hence, for
securing fair and transparent financial markets.
