Trading on margin means that you borrow funds from the broker to buy securities. You only pay a certain percentage (or margin) of the value. This allows you to trade beyond your available balance.
Trading on margin allows you to trade beyond your available cash. You borrow money from the broker to do this. Your open securities positions and cash holdings serve as collateral in this case.

The swap is a typical trading fee in Forex and CFD trading. As they are leveraged derivatives, a financing fee (swap) of the trading position is required. The swap depends on the position size, asset, leverage, and broker.
