What sort of rules are you envisaging here? I know the FCA here in the UK does have a host of requirements like negative account protection, max leverage of 1:30 and access to compensation in the event of broker insolvency.
For me, I don’t know if more regulations are needed. I think it’s more about educating beginners about the risks and challenges of day trading so newbies go into it with their eyes wide open.
