SoFi's Self-Directed Invest accounts are margin accounts because this allows you to trade with unsettled funds. However, by default, that does not mean you are able to use leverage for Margin trading. If you would like to use leverage and trade on margin, you must first apply for it and be deemed eligible. Please go to the Margin section of our Invest Help Center to learn more: Margin Trading
SoFi’s IRA accounts are cash accounts. You are not able to trade with unsettled funds.
