Margin Call Explained: Margin Level, Leverage and Stop-Out

A trading account can show a positive balance and still be close to forced liquidation. The balance records money already booked to the account. Open losses can leave much less equity available to support the positions that remain.
A margin call concerns that relationship: the account no longer meets a specified margin condition. Depending on the provider’s rules, this can produce a warning, a requirement to restore margin coverage, or restrictions on trading.
The important numbers are the equity available now, the margin required now and the broker’s intervention thresholds. A deposit made last week says little about today’s margin position.
1. Equity and Margin: What Is Supporting the Trade?
Consider an account with a balance of USD 3,600 and open positions showing a combined loss of USD 1,200.
Ignoring credits and other adjustments:
Equity = Balance + Unrealised profit or loss
USD 3,600 − USD 1,200 = USD 2,400
The balance still reads USD 3,600, but the account’s equity is USD 2,400.
Now suppose the provider requires USD 1,500 of margin for those positions. Margin is collateral required to support exposure. It is not a trading fee deducted from equity, and it is not a ceiling on possible losses.
Under the simplified calculation:
Free margin = Equity − Used margin
USD 2,400 − USD 1,500 = USD 900
These figures describe different things:
Account figure | What it tells you |
Balance | The amount recorded after booked transactions, excluding current floating profit or loss |
Equity | The account’s current value, including floating profit or loss and applicable adjustments |
Used margin | The collateral requirement attributed to the positions |
Free margin | Equity remaining after the margin requirement is deducted |
Exact treatment of credit, commissions, blocked funds and other adjustments depends on the account. MetaTrader’s account display distinguishes these components rather than treating the balance as the complete picture.
Free margin is also not a recommended spending allowance. Using all available capacity to open more positions can leave little room for an adverse move.
2. Margin Level: Turning Coverage into a Percentage
A common platform calculation expresses equity relative to used margin:
Margin level (%) = Equity ÷ Used margin × 100
MetaTrader 5 uses this equity-to-margin relationship for its margin-level display.
For the account above:
USD 2,400 ÷ USD 1,500 × 100 = 160%
That means equity equals 1.6 times the margin requirement. It does not mean the account has earned 160%, or that 160% of the balance can be lost.
The percentage changes when either side of the calculation changes:
- Falling equity reduces margin level.
- A higher margin requirement also reduces margin level.
- Releasing used margin can increase the percentage without recovering a trading loss.
If no margin is being used, this division has a zero denominator. The platform may leave the field blank or display a special value; it should not be read as an ordinary percentage.
3. What Causes a Forex Margin Call?
Open losses are one route to a margin call, but they are not the only one.
Losses consume equity
A position can remain open while its loss grows. Until that loss is booked, the balance may look largely unchanged, even as equity and margin coverage deteriorate.
Several positions can contribute at once. Separate order tickets do not necessarily represent separate risks: multiple trades exposed to the same currency move may lose value together.
Additional trades increase the requirement
Opening another position can raise used margin. Even before a substantial new loss develops, the account may have less coverage relative to its obligations.
Margin requirements change
The denominator is not necessarily fixed. Requirements can vary with instrument rules, exposure tiers, exchange rates or changes announced by the provider. FXCM, for example, states that margin requirements can change with volatility and exchange rates.
Costs and withdrawals reduce available support
Posted financing charges, commissions or withdrawals can reduce equity. Wider spreads can also worsen the valuation of open positions.
This is why forex leverage risk cannot be assessed from the advertised leverage ratio alone. The account’s exposure, losses, costs and collateral requirements must be considered together.
4. Margin Call and Stop-Out Are Different Events
A margin call identifies an account that has reached the provider’s specified margin condition. Stop-out refers to forced position reduction or closure under the applicable closeout rules.
The distinction matters because a warning does not reserve time for a recovery.
For a concrete example, Pepperstone’s EU support page describes an MT4/MT5 margin-call warning when margin level falls below 90%. It identifies 50% as the retail stop-out threshold and describes closing positions beginning with the largest losing trade. These are provider-, platform- and client-specific rules, not universal forex thresholds.
Other arrangements may use different percentages, calculations or liquidation methods. Some systems reduce positions in portions; others close whole positions.
Do not assume “margin call” means a telephone call or a guaranteed opportunity to transfer funds. Pepperstone’s product disclosure also warns that market movements may reach closeout conditions before contact is made.
A stop-out is separate from a stop-loss order. A stop-loss follows an instruction attached to a trade. Stop-out follows the account’s margin condition and the provider’s liquidation policy.
5. Worked Example: Following the Account Towards Stop-Out
The following exercise uses hypothetical account figures and the published 90% warning / 50% retail stop-out reference described above.
It assumes:
- A USD 3,600 balance.
- USD 1,500 of used margin, held constant for the exercise.
- No deposits, withdrawals, credit or separately posted charges.
- Floating losses already reflecting the assumed position valuations.
The constant margin requirement is a teaching assumption. A live account may recalculate margin.
Account snapshot | Floating P/L | Equity | Used margin | Margin level |
Starting snapshot | USD 0 | USD 3,600 | USD 1,500 | 240% |
Losses increase | −USD 1,350 | USD 2,250 | USD 1,500 | 150% |
Below the cited warning level | −USD 2,265 | USD 1,335 | USD 1,500 | 89% |
Below the cited stop-out threshold | −USD 2,865 | USD 735 | USD 1,500 | 49% |
At the warning snapshot:
USD 1,335 ÷ USD 1,500 × 100 = 89%
The account still has positive equity. However, that equity is below the required margin, and the percentage has crossed the cited warning condition.
At the final snapshot:
USD 735 ÷ USD 1,500 × 100 = 49%
That is below the cited retail stop-out threshold. The row illustrates an account condition that would activate the relevant closeout process; it does not predict an exact liquidation price.
Prices can change during execution. The remaining equity after closure may therefore differ from the snapshot.
A 50% Margin Level Does Not Mean Half the Deposit Remains
With USD 1,500 of used margin, a 50% margin level corresponds to:
USD 1,500 × 0.50 = USD 750 of equity
USD 750 is only about 20.8% of the original USD 3,600 balance.
The percentage uses margin as its denominator, not the original deposit. Confusing those two reference points can produce a serious misunderstanding of how much capital remains.
6. Controlling Exposure Before the Warning Appears
The broker’s liquidation threshold answers when its intervention process applies. Your trading plan needs an earlier decision about how much loss you are prepared to accept.
Separate position exposure from the leverage setting
For an unchanged position, a higher permitted leverage ratio does not increase profit or loss per pip. It may reduce the collateral requirement.
The risk increases when that additional capacity is used to carry a larger position relative to equity. This is a central leverage trading risk: an affordable margin requirement can accompany an unaffordable loss exposure.
Test an adverse move across the whole account
Estimate how a specified market move would affect every open position, then recalculate equity and margin coverage.
Include correlated exposure and relevant costs. For instruments whose margin requirement changes with valuation, update the requirement as well.
Understand what reducing a position actually changes
Closing a losing position books an existing loss. It does not, by itself, create another loss equal to the floating amount.
For example, suppose equity is USD 1,335 and used margin is USD 1,500. If a partial closure releases USD 750 of margin while equity remains unchanged before additional costs:
USD 1,335 ÷ USD 750 × 100 = 178%
Margin level rises from 89% to 178%, although the account has recovered no money. Its remaining collateral requirement is smaller, and its exposure has been reduced.
Actual margin released depends on the instrument and account rules.
Do not treat funding as an automatic solution
Additional cleared funds can improve coverage, but they leave the market exposure in place unless the position is also changed. Transfers may not arrive before liquidation.
Review the exposure itself rather than assuming another deposit makes the trade acceptable.
Know the rules before they become urgent
Confirm the warning threshold, closeout threshold, calculation method, liquidation sequence and notification arrangements for your specific account. Check ordinary stop-order execution rules separately: a requested exit price may not be guaranteed.
A rising margin percentage can reflect reduced exposure rather than recovered capital. A positive balance can coexist with severe floating losses. Read equity, used margin and position size together to understand what the account is actually carrying.
Frequently Asked Questions
1. What is a margin call in forex trading?
A margin call means an account has reached the provider’s specified margin condition. It may trigger a platform warning, a request to restore coverage or trading restrictions. It does not necessarily involve a telephone call or give you a guaranteed period to act before positions are closed.
2. How is margin level calculated?
The common formula is Margin level (%) = Equity ÷ Used margin × 100. For example, USD 2,400 of equity and USD 1,500 of used margin produce a margin level of 160%. This percentage measures equity relative to the margin requirement; it is not a return on investment.
3. Can I receive a margin call while my balance is positive?
Yes. Balance excludes current floating profit or loss, whereas equity reflects the value available after those results and applicable adjustments. An account can retain a positive balance while open losses substantially reduce its equity. Margin coverage therefore cannot be assessed from the balance alone.
4. What is the difference between a margin call and stop-out?
A margin call identifies a specified margin condition; stop-out is the forced reduction or closure of positions under the provider’s rules. Warning levels, closeout thresholds and liquidation methods depend on the account and platform. Do not assume that another broker’s percentages apply to yours.
5. Does a 50% margin level mean half my deposit remains?
No. The percentage compares equity with used margin, not with your original deposit. If used margin is USD 1,500, a 50% margin level corresponds to USD 750 of equity. Against an initial USD 3,600 deposit, that is approximately 20.8%, assuming no other account transactions.
6. Does higher leverage make each pip worth more?
For an unchanged position size, changing permitted leverage does not change profit or loss per pip. It can change the margin required to hold that position. Monetary exposure per pip increases when you increase the amount traded. Using higher leverage to carry a larger position can therefore accelerate losses relative to equity.
7. Why can closing a losing trade improve margin level?
Closing a trade can release used margin. The floating loss becomes realised, so closing does not itself recover that money. If equity stays at USD 1,335 while used margin falls from USD 1,500 to USD 750, margin level rises from 89% to 178%, before additional costs or price changes.
8. Will adding money prevent a stop-out?
Additional cleared funds can improve margin coverage, but a pending transfer does not guarantee protection. Prices may move further before the funds arrive, and margin requirements may change. Funding also leaves the existing market exposure in place. Check the account’s live equity, margin requirement and closeout rules rather than relying on the deposit alone.
