Several brokerages offer a paper trading option so there’s no need to risk real money or fear accidentally leveraging yourself. Just google paper trading, I think thinkorswim has it along with others. If using an actual account just don’t use options and don’t apply for margin when you open the brokerage. It will be a cash only account and you won’t be able to lose more than you put in (assuming we’re talking stocks and bonds here, not Futures).
