I agree. Thanks for elaborating more on the 5 criteria. Indeed, I should also have mentioned your points as well.
I met someone 2y ago during a meetup (not from this forum, but another one) who lived in canton Schwyz and just sold put options. He didn’t use leverage at all, but of course it was not hedging in his case (how can selling put options and earning the premium be counted as hedging anyway?), and yet still he was classified as a professional trader and had to pay capital gains plus AHV on his trading profits. I don’t know about his trading volume though. Unfortunately, I don’t have his contact details, but maybe I’ll meet him during the next month.
