Stop Out vs Margin Call: What They Mean in Forex Trading

Most traders hear the words margin call and stop out only after something has already gone wrong. A trade moves against them, a warning appears on the screen, and then positions start closing without any action on their part. Understanding these two terms before it happens is one of the simplest ways to protect your account. In this guide, we explain what margin, margin level, margin call and stop out mean, show how the numbers work with a worked example, and share practical habits that keep you away from forced closures.

What is margin?

Margin is the amount of your own money that your broker sets aside to keep a leveraged position open. It is not a fee, and you get it back when the position is closed. Think of it as a good faith deposit that supports the trade while it is running.

The size of the margin depends on the position size and on your leverage. If you open a larger position, more margin is needed. If your leverage is higher, less margin is needed for the same position. This is why leverage lets you control a big position with a small amount of capital, and also why it needs to be handled with care. Our guide on the risks of high leverage trading goes deeper into this point.

The key terms on your platform

On MetaTrader 4 and MetaTrader 5, a few numbers are shown at the bottom of the screen in the trade tab. It helps to know what each one means.

Balance is the money in your account without counting any open trades. Equity is your balance plus or minus the floating profit or loss on open positions. Margin, sometimes called used margin, is the amount currently locked in your open positions. Free margin is the money you still have available to open new trades or absorb losses. It equals your equity minus your used margin.
Margin level is the number that matters most here. It is calculated as equity divided by used margin, multiplied by 100, and it is shown as a percentage.

What is a margin call?

A margin call is a warning. It happens when your margin level falls to a level set by your broker, which tells you that your account no longer has a comfortable cushion. At that point, you usually cannot open new positions, and you are expected to act, either by adding funds or by reducing your exposure.

In practice, many traders do not receive a dramatic phone call. The warning appears as a notification or a change in your platform, and your account may be restricted from opening new trades. The exact margin call level differs from broker to broker and between account types, so you should check the specifications for your own account rather than assuming a number.

What is a stop out?

A stop out is the automatic closure of your positions. It happens when your margin level falls further, to the stop out level set by your broker. The system then begins to close positions, usually starting with the one that is losing the most, until your margin level goes back above the required level.

The purpose is protective. It is meant to stop losses from growing beyond what your account can support. But from a trader's point of view, it also means that a trade you wanted to hold can be closed at a loss without your approval.

The margin call level is always higher than the stop out level. You can think of it as a yellow light, followed by a red light.

A worked example

Let us use simple numbers. Imagine you deposit $1,000 and open positions that require $400 of margin. With no floating profit or loss, your equity is $1,000.

Your margin level is 1,000 divided by 400, times 100, which is 250 percent. That is a healthy level.
Now the market moves against you, and your floating loss reaches $700. Your equity drops to $300. Your margin level is now 300 divided by 400, times 100, which is 75 percent.

Suppose, for this example, that the stop out level is 50 percent. The system would begin closing positions when equity falls to half of the used margin, which is $200. That means a floating loss of $800 would trigger it, while you had only $1,000 to begin with.

The numbers in this example are illustrations, and your own account levels may be different. What matters is the logic. A relatively small amount of margin can support a large position, but the cushion between your equity and the stop out line is what keeps you in the trade.

Why traders get stopped out

The most common cause is a position that is too large for the account. When you use most of your balance as margin, you leave very little room for the price to move against you. Even a normal fluctuation can push the margin level down to dangerous levels.

The second cause is too much leverage combined with no stop loss. A trade without a stop can slowly eat into your equity while you wait for a reversal that does not arrive.

The third cause is trading around major news. Events like the non farm payroll release can move prices sharply in seconds, and the gap between your entry and the price can widen quickly. Our guide on how to handle extreme volatility during the NFP release covers this in detail.

The fourth cause is adding to a losing trade. Opening more positions to average down increases your used margin at the same time that your equity is falling, which pushes the margin level down twice as fast.

How to avoid a margin call and a stop out

Start with position sizing. Decide how much you are willing to lose on a trade, based on a small percentage of your account, and size the trade from your stop loss distance. Then check how much margin it requires. If the margin is a large share of your balance, reduce the size.

Always use a stop loss. It limits the loss on each trade before the platform has to step in. A stop you control is far better than a stop out that the system controls.

Keep free margin. Many traders try to keep a comfortable level of free margin at all times, so a sudden move does not leave them close to the stop out line. Avoid opening several large positions at once.

Watch your margin level. It is shown in real time on the platform. If it starts to fall quickly, act early by closing part of the position or adding funds, instead of waiting for the warning.

Be careful around news. Reduce size or stay out of the market during major releases, when prices can jump and spreads can widen.

Stop out and bonus accounts

If you use a promotional bonus, it is worth reading the terms with the stop out in mind. In the terms of the 30% deposit bonus, for example, a stop out on the account causes the bonus to be written off. That makes it even more important to size positions carefully and keep a healthy margin level while the bonus is active.

Does a stop out mean you lose everything?

Not necessarily. A stop out closes positions to protect the account, and the amount you lose depends on the trades that were open and the prices at which they were closed. Still, it often leaves a much smaller balance than the one you started with, and in fast markets, prices can slip beyond the level you expected. Some brokers also offer negative balance protection, which is worth checking, and you can read what to look for in our guide on negative balance protection.

Final thoughts

A margin call is the warning, and a stop out is the automatic closure that follows if the warning is ignored. Both are tied to your margin level, which compares your equity with the margin used by your open trades. If you size your positions with care, use stop losses and keep a cushion of free margin, you can avoid most forced closures and stay in control of your trades.
