Onvista Bank and thus also the broker cease operations.
The Commerzbank ($CBK ) subsidiary intends to cease business operations.
New customers have not been accepted for a while and existing customers have to find a new broker for the transfer.
(Incidentally, if you want to join the parent company, you have to open a new securities account).
Some Onvista users I know have already started switching, even if it is already time.
Flatex tends to be quite high up in the rankings, rather than the classic new brokers.
