Are we allowed to swing trade in foreign stock markets?

Just out of curiosity, can I do swing trades in US, EU, HKEX and other stock markets legally? Only day trading is banned right? Also, is there a minimum holding duration or something?


But Margin trade is not allowed. Is it possible to start a foreign company as a shell to legally trade derivatives also? I saw another thread about this, but it was not very definitive.

Thanks for replying!
