Online trading platforms offer various types of instruments, including stocks, ETFs, forex, futures, and options. If you are a non-US trader who wants to trade in the U.S. markets, you can if you have the necessary paperwork. So if you are a U.S. resident but not a citizen or a non-US citizen living outside of the U.S., you can open an account with an international or U.S.-based broker that accepts applications from your country of residence.
