Almost all online banks offer free brokerage accounts. There are always tests on this. For example, here: https://madamemoneypenny.de/aktiendepot-konten (GERMAN). I've had mine at ING-DIBA for years and I'm very satisfied with it. If you would like to open one there as well, please use the following link: https://www.ing.de/depotkwk/a/FhStoEueTB*. For every new customer acquired, 40 euros are donated to Unicef. This way we will do something good together and helped others with your step into independence.  *PS: This is not paid advertising, I use the depot myself too and receive nothing except this Unicef donation for my recommendation.
