A Webull (https://www.webull.com) account is probably what you want. I want to make something clear to you as a private person, however. These accounts are like opening a bank account. They require lots of information including bank account numbers and drivers license photo.
Hmm, sounds ultra complex. Not what DH would like to do!
BTW I want to put a link on my twtter to a Niatonin site, what would be the best one that people can follow if they want?
