Direct answer
You get margin called in forex when the value of your account equity falls below the broker’s required margin level for your open leveraged positions. This is usually caused by adverse price movement against your positions, which reduces equity and can make your account no longer meet the margin requirement.
How a margin call works (key terms)
In forex, you typically control a position that is larger than your cash deposit using leverage. Two simple ideas matter:
- Margin requirement: the amount of funds the broker expects you to have to keep a position open.
- Equity: your account’s total value, generally including your cash balance plus (or minus) unrealized profit and loss (P/L) from open trades.
A margin call is triggered by your broker’s system when equity declines relative to the required margin for your current open positions. Because leveraged trades can produce unrealized losses quickly, equity can deteriorate even if you have not closed the trade.
Common pathways to a margin call include:
- Adverse price movement: your position moves against you, creating unrealized losses.
- High leverage / large position size: more exposure means equity changes faster.
- Withdrawals or reduced available funds: lowering free margin makes it easier to breach margin thresholds.
Example checks you can use
Consider a leveraged long position: if the forex price falls, your unrealized loss increases, which reduces equity. If that reduction is enough that your equity-to-margin relationship drops below the broker’s required level, a margin call can be generated.
You can independently sanity-check the situation using two values your platform usually shows:
- Unrealized P/L: does it look increasingly negative?
- Margin level / free margin: is the platform displaying a declining buffer toward a minimum threshold?
If your broker also uses an automated stop-out rule, trading may be forcibly reduced or closed after certain margin thresholds are reached. The specific thresholds and sequence vary by broker and account settings, so treat this as a general mechanism rather than a universal rule.
Limitations and uncertainties
Margin calls are broker- and account-dependent. The exact calculation (and labels like “margin level”), the thresholds, and whether partial or full liquidation occurs can differ. Without your broker’s current terms, platform definitions, and account settings, you can only verify the concept, not the precise trigger.
Also, this explanation is informational. It does not predict when a margin call will occur in your specific situation, because real timing depends on live prices, your open exposure, and the broker’s rules at that time.
If you want, you can check your broker’s platform for the definitions of equity, margin requirement, margin level, free margin, and the displayed minimum thresholds.
