INSIGHTSA margin call occurs when a brokerage firm requires an investor to deposit additional funds or securities into their margin account to cover potential losses. This typically happens when the equity in the account falls below a certain threshold, set by the broker. In many trading environments, the minimum equity requirement is usually a percentage of the total account balance, often referred to as the maintenance margin.
When a margin call is issued, the trader has a limited timeframe to respond, either by adding more capital or liquidating positions to reduce their leverage. If the margin call is not met, the broker may liquidate positions to cover the shortfall, which can lead to significant losses for the trader.
