Margin Call: Causes and Ways to Avoid It to Protect Your Trading Account
A margin call is one of the most important and serious concepts in the Forex market, as ignoring it can lead to the loss of a significant portion of your capital or even the forced closure of your trades by the brokerage firm.
Therefore, properly understanding how margin works and managing risk are the cornerstones of any trader’s longevity in the financial markets.
Here, we’ll review the concept of a margin call, the reasons it occurs, the factors that increase the likelihood of experiencing one, as well as the most important practical strategies for avoiding the forced liquidation of positions.
What Is a Margin Call?
A margin call is a notification or alert issued by a brokerage firm when the equity in a trading account falls to a level close to the used margin, indicating that the account no longer has sufficient liquidity to cover floating losses.
If losses continue and the margin level falls below the threshold set by the brokerage firm, a process known as “forced liquidation” , where the platform automatically closes losing positions to protect the broker from the account balance turning negative.
How does a margin call occur?
The margin level depends on the ratio of equity to used margin, according to the following formula:
Margin Level (%) = (Equity ÷ Used Margin) × 100
When equity declines due to floating losses, the margin level begins to drop gradually until it reaches danger levels.
Common Margin Levels
- Over 500%: Extremely safe.
- Between 300% and 500%: A comfortable and stable situation.
- Between 100% and 200%: A warning zone that requires caution.
- 100% or less: High risk; margin call alerts may begin.
Stop-Out Level: The platform begins automatically closing positions in accordance with the brokerage firm’s policy.
Main Causes of Margin Calls
1. Using position sizes larger than the account balance
Poor management of position size is the most common cause of margin calls.
When a trader opens positions that are large relative to their capital, even a small price movement against the position can deplete a significant portion of the available margin.
2. Excessive use of leverage
Leverage allows you to control large positions with a small amount of capital, but it amplifies losses just as quickly as it amplifies profits.
The higher the leverage, the greater the likelihood of receiving a margin call during periods of high volatility.
3. Trading Without Stop-Loss Orders
The absence of stop-loss orders leaves losses open-ended and unlimited, which can rapidly erode margin when the market moves sharply.
4. Overtrading
Opening a large number of trades at once consumes a significant portion of free margin and reduces the account’s ability to withstand sudden fluctuations.
5. Ignoring the Impact of Economic News
Major economic events such as:
- Interest rate decisions.
- Inflation data.
- The U.S. Nonfarm Payrolls (NFP) report.
- Central bank press conferences.
These can cause sharp price movements and widening spreads, leading to significant losses in a short period of time.
The Best Ways to Avoid Margin Calls in Forex
- Manage position size professionally
The golden rule among most professionals is to risk no more than 1% to 2% of your capital per trade.
For example:
An account with a balance of $1,000.
Risk percentage: 1%.
Maximum allowable loss = only $10.
This strategy helps ensure the account can withstand a series of losing trades without coming close to a margin call.
- Use moderate leverage
Many experts recommend using leverage ranging from 1:10 to a maximum of 1:50.
This is preferable to high leverage ratios such as 1:500 or 1:1000, which significantly increase the account’s risk.
- Strictly adhere to stop-loss orders
Before entering any trade, you must determine:
The entry point.
Stop-loss level.
Price target.
Risk-to-reward ratio.
You should also avoid widening the stop-loss after entering a trade in the hope that the price will rebound.
- Continuously monitor the margin level
You should track:
Used Margin.
Free Margin.
Margin Level.
It is best to maintain a high margin level, which gives the account sufficient room to withstand market fluctuations.
- Maintain Reserve Liquidity
A common mistake is using all of your capital for trading.
Keeping a portion of your balance unused helps absorb sudden fluctuations and reduces the likelihood of receiving a margin call.
- Avoid Correlated Risks
Many traders make the mistake of opening multiple positions on correlated currency pairs such as:
EUR/USD
GBP/USD
AUD/USD
Although these appear to be different trades, they are often influenced by the same factors—especially if upcoming news involves the U.S. dollar, which is the common factor among them—thereby doubling the actual risk to the account.
Warning Signs Before a Margin Call
There are several indicators that signal an account is approaching the danger zone, most notably:
- A continuous decline in the margin level.
- Rising floating losses.
- Depletion of most of the free margin.
- Opening successive stop-loss trades without a clear plan.
- Relying on high leverage.
- Holding losing trades for long periods without a stop-loss.
Can a margin call be used as a risk management signal?
In fact, a trader should not wait until the account reaches the margin call stage.
Professional traders manage risk proactively by controlling position sizes, allocating capital, and using protective orders.
Therefore, a margin call is often an indication of a flaw in capital management rather than just a passing event.
Ultimately, a margin call is one of the greatest risks facing Forex traders, but at the same time, it is one of the most avoidable risks through proper capital management.
Success in Forex does not depend solely on making profits; rather, it depends primarily on the ability to protect capital and avoid mistakes that could lead to significant losses or permanent exit from the market.
