TradeZero_Dan

I am an American living in South Korea. I want to open an account with tradezero. I am a bit confused because some people say I am allowed and some said Im not. Can you clarify all this for me ? Its getting a abit confusing .

Hello, I have a manual routing account for tradezero, but its commission is $0.005 per share. I want to know whether the commission can be reduced if I have enough trading volume every day. Thank you.
