To determine your leverage, you need to check the specific settings of your trading account on the StocksTrader platform. Leverage is a ratio between your own funds and the borrowed funds from your broker. For example, if you have a leverage of 1:500, you can control a larger position with a smaller amount of your own capital. Different instruments have varying leverage limits. For instance, currency pairs can have leverage up to 1:500, while CFDs on US stocks are typically up to 1:20. It is important to note that currency pairs and other CFDs may not be available for trading, please contact your broker's customer support to confirm the availability of specific trading instruments. 

You can find the exact leverage applicable to your account by referring to the "Contract Specifications" section on the platform. If you need a different leverage ratio, you will have to open a new account with the desired settings.
