How Margin Level and Free Margin Affect
Your Forex Trades?

Margin level and free margin are two important figures shown on many forex trading platforms.

They help show how much of the account is being used to support open positions and how much remains available under the platform’s margin rules.

These numbers can change while trades are open. This happens because forex prices move, and open positions may show changing unrealized profit or loss.

For beginners, margin level and free margin can seem difficult at first. But the main idea is simple. Margin level shows the relationship between account equity and used margin. Free margin shows the amount not currently being used to support open positions.

This article explains both terms in simple English. All examples are for educational purposes only. They are not live prices or trading recommendations.

What Is Used Margin?

Used margin is the amount currently being used to support open positions.

For example, imagine a forex position requires 200 US dollars in margin. While that position is open, the 200 US dollars becomes used margin.

If another position is opened and it requires 100 US dollars in margin, the total used margin becomes 300 US dollars.

Used margin is not usually a fee. It is the amount set aside by the platform to support open positions under the provider’s margin rules.

When a position is closed, the margin used for that position is normally released, subject to the final account result and any applicable charges.

What Is Free Margin?

Free margin is the amount that is not currently being used to support open positions.

A simple way to understand it is:

For example, imagine an account has equity of 1,000 US dollars and used margin of 200 US dollars.

The free margin is:

This means 800 US dollars is not currently being used as margin for open positions.

However, free margin can change as open positions move. If the open position shows a larger negative movement, equity may fall and free margin may also fall.

What Is Margin Level?

Margin level is usually shown as a percentage.

It compares equity with used margin.

A common calculation is:

For example, if equity is 1,000 US dollars and used margin is 200 US dollars, the margin level is:

This means the equity is five times the used margin in this simple example.

If equity falls while used margin stays the same, the margin level also falls.

The exact formula and platform rules should always be checked with the provider, because margin settings can vary.

How Open Positions Affect Free Margin?

Free margin changes when open positions change in value.

Imagine an account starts with:

Now imagine the open position shows an unrealised negative movement of 100 US dollars.

The equity becomes 900 US dollars.

The used margin remains 200 US dollars.

The free margin becomes:

The position is still open, but the free margin has decreased because equity has decreased.

This shows why free margin can move even when no new position is opened.

How Open Positions Affect Margin Level?

Margin level also changes when equity changes.

Using the same example, the account first has:

The margin level is:

Now equity falls to 900 US dollars while used margin remains 200 US dollars.

The margin level becomes:

The used margin did not change, but margin level became lower because equity became lower.

If equity continues to fall, margin level may continue to fall. If it reaches certain platform levels, a margin warning, margin call or stop-out process may apply, depending on the provider’s rules.

Why Free Margin Matters?

Free margin matters because it shows the account amount not currently used to support open positions.

A lower free margin means there is less available margin under the platform’s rules.

If free margin falls too much, the account may have limited ability to support open positions or open new ones.

Free margin can be affected by market movement, position size, spreads, commissions, financing charges and currency conversion.

It is important to understand that free margin does not predict market direction. It only shows part of the account’s current margin condition.

Why Margin Level Matters?

Margin level matters because it gives a percentage view of the account’s margin condition.

Many platforms use margin level to decide when warnings or automatic actions may apply.

For example, a provider may have a margin-call level and a stop-out level. These levels can vary by account type, product and jurisdiction.

If the margin level falls below a certain point, the platform may issue a warning. If it falls further, the platform may close one or more open positions automatically according to its rules.

The exact levels and process should be checked in the platform’s margin policy or client agreement.

Margin Call and Stop-Out

A margin call is a warning or platform action linked to low available margin.

It may happen when the account no longer has enough margin support under the provider’s rules.

A stop-out is usually the level where the platform may begin closing open positions automatically because the margin level has fallen too low.

These processes are not the same on every platform.

One provider may use one margin-call level. Another provider may use a different level. Some platforms may close the largest position first. Others may follow different rules.

Beginners should not guess these rules. They should read the provider’s margin policy, client agreement and product conditions.

How Trade Size Affects Margin Level and Free Margin?

Trade size has a direct effect on used margin.

A larger trade size usually requires more margin than a smaller trade size, if the same currency pair and margin requirement are used.

For example, a 0.10 lot position may require less margin than a 1.00 lot position under the same conditions.

A larger trade size can also make each pip movement have a larger effect on equity.

This means a larger trade size can affect both used margin and equity more strongly.

Because margin level and free margin are linked to equity and used margin, trade size is an important factor to understand.

How Leverage Affects Margin Conditions?

Leverage affects how much margin is required for a position.

Higher leverage usually means a lower margin requirement for the same position size. Lower leverage usually means a higher margin requirement.

However, leverage does not reduce the full market exposure of the position.

A position with lower required margin can still have a large account effect if the trade size is large and the market moves.

This is why free margin and margin level should not be viewed alone. They should be reviewed together with trade size, leverage, pip value and product conditions.

What Beginners Should Check on the Platform?

Before opening a forex position, beginners should check the margin details in the order window or product specification.

They should review the trade size, used margin, free margin, margin level, leverage, pip value and spread.

They should also understand the platform’s margin-call and stop-out rules.

It is useful to check how the platform calculates equity and how often the values update.

These checks do not remove risk. They simply help explain how the account may react when market prices move.

Common Mistakes to Avoid

One common mistake is looking only at balance.

Balance does not always show the full picture when positions are open. Equity, free margin and margin level can change while trades are open.

Another mistake is thinking free margin is fixed.

Free margin changes as equity changes. It can increase or decrease depending on open positions and account conditions.

A third mistake is ignoring used margin.

Used margin shows how much of the account is currently supporting open positions. If used margin is high and equity falls, margin level can drop quickly.
