A margin account is a type of brokerage account that allows traders to borrow funds from a broker to trade financial assets. By using leverage, traders can increase their purchasing power, which can amplify potential gains. However, this also increases the risk of losses.
When a trader uses a margin account, they are typically required to deposit a certain percentage of the total trade value, known as the margin requirement. The trader can then borrow the remaining funds from the broker. If the value of the assets in the margin account declines significantly, the broker may issue a margin call, requiring the trader to deposit additional funds or sell assets to maintain the required equity.
