Yes, it is possible to buy real stocks with leverage on the StocksTrader platform. You can choose different leverage ratios based on your account type and preferences. Leverage does not have to be 1:1, you can select higher leverage ratios depending on the financial instruments you are trading. 

Make sure to open contract specifications to check whether higher leverage is available for the specific instrument you are interested in. However, it's important to note that using leverage increases both potential gains and risks.
