What is the best way to begin trading stocks under 18? I have been using the practice account on Trading-212, and I've made a decent amount of money trading small scale. I was wondering what the best way to start trading stocks is for under 18's, as all online services I have seen require you to send ID, yet I have read success stories about people becoming millionaires whilst still in school. I have done a bit of research into this and the best way, at least in the UK, is to set up and ISA account, and give a your parent/ guardian control over it, so 'they' can buy stocks. The only issue with this is that there is a cap on how much you can put in the account per year, which is a measly 4k at most banks So do you have any suggestions or experience with this?
