I have gotten approval in a few different jurisdictions for retail derivs trading. The barrier to entry is pathetically low in all cases. Literally: Tick a box to agree if you accept risk and are "qualified".
I assume it's a compliance requirement, they get a record of me having said the right things at one time and don't really know if I got someone else to tell me what to answer. Still, I think it's actually keeping some people out, judging from some forum threads where they try to get help to pass and seemingly fail even though others are telling them basically what to respond with.
