What Is a Margin Call in Forex and What Is a Stop-Out Level?

Most traders meet the margin call for the first time on the worst day of their trading account. Knowing the arithmetic in advance lets you see it coming days earlier.

What people on X are asking

Educational posts keep asking and answering this. One from October 2026 asked what a margin call is and explained it as a threshold of the margin level. Another, from January 2026, asked what margin level is and gave the formula. A November 2026 post from a broker account described how a margin call comes first and a stop-out follows if the level keeps falling. We do not recommend any broker; the mechanics below apply generally.

The fact-checked answer

Four numbers on your platform.

• Balance: deposits plus closed profits and losses.
• Equity: balance plus or minus the open profit and loss right now.
• Used margin: the deposit locked up by open positions. At 50:1 leverage it is 2% of the position value.
• Free margin: equity minus used margin, what is left to absorb losses or open trades.

Margin level. Margin level = equity ÷ used margin × 100. If equity is $2,000 and used margin is $1,000, the margin level is 200%.

The two thresholds. Brokers set a margin-call level (often around 100%, sometimes higher) and a stop-out level below it (often somewhere between 20% and 50%). These values are not standard across the industry. They are in your broker's terms, and offshore brokers' rules can be very different from those of US firms regulated by the CFTC and NFA. FINRA and Investor.gov describe the same idea for stock margin accounts: if equity falls below the maintenance requirement, the firm can sell your positions without asking.

Worked example: one EUR/USD position as price moves against you

Illustration by UXS: $3,000 account, one standard lot (100,000 units) long EUR/USD at 1.1000, $10 per pip, 2% margin ($2,200). Thresholds are example values, not a specific broker's. Tap a column header to sort.

EUR/USD	Open loss	Equity	Used margin	Margin level	What happens (100% call / 50% stop-out)
1.1000 (entry)	$0	$3,000	$2,200	136%	Normal
1.0950	−$500	$2,500	$2,200	114%	Normal, but free margin only $300
1.0920	−$800	$2,200	$2,200	100%	Margin call: no new trades
1.0880	−$1,200	$1,800	$2,200	82%	Below call level
1.0810	−$1,900	$1,100	$2,200	50%	Stop-out: position closed

The striking part: a 190-pip move (about 1.7%) took this account from healthy to forced closure, because one standard lot was far too large for $3,000. With one mini lot the same move would have cost $190.

UXS decision diagram

What should I do when the margin level falls?

Text version of the diagram

1. Is the margin level above 200%? If yes: Comfortable buffer: keep monitoring
2. Is the trade still valid by your original plan? If no: Close it yourself before the broker does
3. Would adding funds just delay a loss you planned to accept? If yes: Do not deposit to rescue it: take the planned stop
4. Can you reduce size to restore the buffer? If yes: Close part of the position to raise the margin level
5. Otherwise: If none of these apply, expect a stop-out at the broker's level and plan the next trade smaller

Stock accounts work differently; see what happens if you can't meet a margin call on a stock account.

How much margin you must post depends on the regulator; see why US brokers limit leverage to 50:1 on majors.

Checklist to avoid margin calls

1. Size trades from your stop distance and risk limit, not from available margin; see how lot size works.
2. Keep total used margin a small fraction of equity.
3. Add up exposure across correlated pairs (EUR/USD and GBP/USD often move together).
4. Know your broker's margin-call and stop-out levels in writing.
5. Check whether margin requirements rise before weekends or major news.
6. Set stop-losses so that you exit long before the stop-out level.

Common mistakes

• Watching balance instead of equity. Balance does not change until you close trades.
• Treating the stop-out as a stop-loss. It fills at market, often at the worst moment.
• Opening more trades because free margin is still positive.
• Assuming stop-out levels are the same everywhere.
• Using offshore leverage of 500:1 and wondering why accounts vanish; see how much leverage to use.

FAQ

What is margin level in forex?

Equity divided by used margin, times 100. A higher number means more buffer.

What is the difference between a margin call and a stop-out?

A margin call is a warning that stops new trades; a stop-out is the broker closing positions automatically at a lower margin level.

Which position gets closed first at stop-out?

Many platforms close the position with the largest loss first, then re-check the margin level; rules vary by broker.

Can I lose more than my deposit?

In fast markets, positions can close beyond the stop-out level. Some brokers offer negative balance protection; check your contract and regulator.

Should I deposit more money after a margin call?

Only if the original trade plan is still valid and the deposit does not simply delay a loss. Usually reducing size is the better fix.

Why did I get a margin call with only one trade?

Because the position was large relative to the account. One standard lot on a $3,000 account uses most of the equity as margin.
