So what are margin and margin level?

Margin is the amount of money set aside in your account to support a leveraged trade. Margin level is a percentage that compares your current account value with the margin already being used.

You already know from What Is Leverage in Forex Trading? that leverage lets you control a larger position than the cash you put down. Margin is the cash the provider sets aside so that larger position can stay open. It is not the full trade size.

Think of margin like a hotel room deposit. The hotel does not charge the deposit as the room price, but it holds the money while you use the room. In trading, the margin is held while the position is open, although your account value can still rise or fall as the market moves.

Beginners often confuse margin with leverage. Leverage describes the relationship between your position size and the money needed to control it. Margin is the money set aside, and margin level tells you how safely or tightly your open trades fit inside your account.

Balance

Your balance is the account value after closed trades and account cash movements have been recorded.

Equity

Equity is your current account value, including running profit or loss on open trades.

Used margin

Used margin is the total money currently set aside to support open positions.

Free margin

Free margin is the part of equity that is not tied up as used margin.

Those four numbers are the margin language you will see on a real trading screen. The next step is to see why they matter before you click buy or sell.

Why margin level can decide what you can do next

Margin level matters because it affects whether you can open new trades and whether existing trades may be restricted or closed automatically. It turns the risk of a leveraged position into a live account number that changes with every price move.

On a trading screen, you will usually see equity, margin, free margin, and margin level near the account summary or order area. If you open a larger position, used margin rises. If an open trade moves against you, equity falls, and margin level falls with it.

Here is the size of the consequence with round hypothetical numbers. If your equity is $1,000 and your used margin is $100, your margin level is 1,000 percent. If the same account has $500 of used margin, the margin level is only 200 percent.

The trade has not been closed in the last row, but the running loss already matters. It reduces equity, reduces free margin, and can bring the account closer to the provider rules for margin call or automatic close out. A margin call is a warning, restriction, or request for more funds when the account no longer has enough room. A close out is an automatic closure of one or more positions under the provider rules.

Providers set their own margin call and close out levels, so you should not memorize one universal number. The habit that transfers across platforms is simpler. Watch how position size and running profit or loss change margin level before the account reaches a forced decision point.

How margin level is calculated step by step

Margin level is calculated by dividing equity by used margin and multiplying by 100. The result shows how much current account value you have compared with the margin already locked behind open positions.

The calculation is simple, but the order matters. First the trade size determines the required margin. Then market movement changes equity. Finally the platform compares equity with used margin to update margin level.

Step 1. The position creates a margin requirement

A position is the trade you open in the market. Its notional value is the full market value of what you control. If you control $10,000 of a currency pair, the notional value is $10,000, even if only part of that amount is set aside as margin.

The margin requirement is the percentage of the position value that must be set aside. If the requirement is 5 percent, a $10,000 position needs $500 of margin. That $500 becomes used margin while the position is open.

Step 2. Equity updates as the open trade moves

Equity is not frozen at your balance. It moves with the market because open profit or loss is included in the account value.

If your balance is $1,000 and your open position shows a running loss of $150, your equity is $850. Closing the position would fix the final result, but the open loss has already reduced the funds available in the account.

Step 3. Free margin shows the room that remains

Free margin is equity minus used margin. It is the account room not currently supporting open trades.

Free margin = equity minus used margin

Equity means the current account value including running profit or loss. Used margin means the money already set aside for open positions.

If equity is $850 and used margin is $500, free margin is $350. That does not mean you should spend the $350 on another trade. It means that, at that moment, $350 is not tied up as margin.

Step 4. Margin level puts the account room into a percentage

Margin level converts the relationship between equity and used margin into one percentage. It is often the clearest margin number on the screen because it updates as both position size and running profit or loss change.

Margin level percent = equity divided by used margin multiplied by 100

Equity is the current account value. Used margin is the total margin supporting open positions. Multiplying by 100 turns the result into a percentage.

If equity is $850 and used margin is $500, the margin level is 170 percent. The account has $1.70 of equity for every $1 of margin being used.

The key point is that margin level can fall in two ways. You can increase used margin by opening or adding positions. You can also lose equity through adverse price movement while positions remain open.

A worked margin level example with one trade

This example shows how one leveraged forex trade changes used margin, free margin, and margin level. The numbers are hypothetical and rounded so you can reproduce the arithmetic.

Assume a trader has a $1,000 balance and opens a $10,000 position in a currency pair. The margin requirement is 5 percent, so the trade uses $500 of margin. After the market moves, the open trade shows a running loss of $150.

The trader still has an open position, but the $150 running loss already affects the account. Equity is now $850, free margin is $350, and margin level is 170 percent.

The useful conclusion is not that 170 percent is safe or unsafe in every case. The useful conclusion is that a $10,000 position used half the original $1,000 account as margin before any market movement happened. A modest running loss then reduced the remaining room from $500 to $350.

This is why margin should be checked before the trade, not after the account feels uncomfortable. The order ticket tells you the position size. The account summary tells you what that position does to used margin and margin level.

How to use margin level before you place a trade

You use margin level by checking how the next trade will change used margin, free margin, and equity sensitivity before you place the order. The point is not to predict the market. The point is to know how much room the account has if the market moves against the position.

Start with the order ticket. Look for the position value, the margin required, or the estimated margin impact. Different platforms use different labels, but the number you need is the amount that will be added to used margin if the trade opens.

Then look at the account summary. Check equity, used margin, free margin, and margin level before you enter. If there are already open trades, remember that a new trade increases used margin while old trades can still change equity through running profit or loss.

• Check the margin required for the new trade before sending the order.
• Compare that amount with current equity, not only with balance.
• Ask what margin level would look like after a reasonable adverse move.
• Read your provider rules for margin call and automatic close out before trading live.
• Reduce position size if the trade would leave too little room for normal price movement.

The beginner trap is to treat margin as permission to trade as large as the platform allows. Margin is better understood as a constraint. It tells you how much of the account is already committed before the market has had a chance to test the trade.

Another trap is watching balance while ignoring equity. Balance can look unchanged while an open trade is losing money. Equity and margin level show the live account condition more clearly because they include the running profit or loss.

Once you can read margin and margin level, the next question is direction. You know what size of position your account can support, but you still need to know what it means to buy or sell a currency pair. Long vs Short: How to Profit in Both Directions answers that next question.
