A margin call is triggered when the equity in your trading account falls below the required minimum margin level.
At FNmarkets, a margin call occurs when your account equity drops to 100% of the required margin. (Margin Level = Equity ÷ Margin × 100%).
When this happens, you are signaled to either deposit additional funds or close some positions to meet the margin requirement. If no action is taken, positions may be automatically closed at the stop-out level (20%) to protect the account from further losses.
