What Is Margining?

Margining is an essential concept to understand in the world of trading. It allows you to leverage your investments and potentially boost your gains, but it comes with its own set of rules and requirements. It's essentially a loan from your broker that enables you to increase your trading power.

Let's dive into margining, with a focus on two key terms: initial margin and maintenance margin.

Initial Margin

Think of initial margin as the ticket to the trading game. To open a position, you must deposit an initial margin, which is a percentage of the total trade value. This margin acts as a security deposit, ensuring you have a stake in the game and can cover potential losses. It's like paying a small deposit when you rent a car.

For example, suppose you want to buy 100 shares of a company's stock at $50 per share. The total trade value is $5,000. If the broker's initial margin requirement is 50%, you need to deposit $2,500 to open the trade. This ensures you have some skin in the game and can cover potential losses up to a certain point.

Maintenance Margin

Maintenance margin is the ongoing check to ensure you can cover potential losses while your trade is active. Think of it as the level you must maintain to stay in the game. If your trade's value drops too much and your account balance falls below the maintenance margin, your broker might issue a margin call.

A margin call is like a referee telling you to keep playing by the rules. You'll be required to deposit more funds to bring your account balance back above the maintenance margin. If you fail to do so, your broker might close your position to limit further losses, similar to a referee ending a match when a player can't continue.


Understanding the difference between initial margin and maintenance margin is crucial. Margining offers the potential for increased gains but also carries a degree of risk. It's essential to use margin carefully, understanding that while it can amplify your profits, it can also magnify your losses. As a beginner it's advisable to start small and gain experience before diving into more significant margin trades.
