SoFi offers individual Active Invest accounts; these are margin accounts. However, we do not offer margin trading at this time.
Margin trading is where you borrow funds from the brokerage firm (ie. SoFi) to make purchases. When you are trading on margin, you pay interest on the money that you are borrowing.
Our individual active accounts are margin accounts that allow you to trade with unsettled funds. When you are trading in a cash account you are required to have settled cash for your purchases by the time the purchase settles. Those actively trading in cash accounts will need to be careful to not violate the cash account trading rules such as Good Faith Violations.
Note: If you have an individual Active Invest account, you are not trading on margin and are not being charged any interest.
