IB or Swissquote for EU nationals

That is correct. (20 chars)

Not su

Trade Republic is for German residents only.

Scalable Capital doesn’t target Swiss customers (
as they used to, for a brief period). While they don’t rule out Swiss customers themselves, it has been reported as unopenable for those.

Finanzen.net zero is another interesting I come across. And they explicitly include Switzerland as a country for account openings (note: seems to be in German only though).

Anyone with experience with the latter?
