Leverage in trading refers to the use of borrowed capital to increase the potential return on an investment. In the context of prop firms, traders can control larger positions in the market with a relatively small amount of capital. For example, with 10:1 leverage, a trader can control $100,000 worth of assets with just $10,000 of their own capital. While leverage amplifies potential profits, it also increases the risk, as losses can exceed the initial investment. Prop firms typically offer high leverage to experienced traders, but they impose strict risk management rules to mitigate the dangers of excessive losses.
