Does swissquote charge just for having an account open (unused) or could I open one for free (never making transactions) so that I can get some bid/ask estimate there to use on Degiro. Also do I read it correctly as saying that I am guaranteed to be able to buy 100000 units at 4.8675 (at that moment)? And if I were to offer in between the bid and the ask nothing would be traded unless/until some other investors / market makers change their sell order?
