What Is a Stop-Out Level? Forex and CFD Close-Outs Explained
In this article
A stop out level is the margin threshold at which a broker begins automatically closing one or more open positions because account equity has fallen too low relative to the margin required to maintain them. It acts as a last-resort risk control when losses reduce an account’s available margin.
So, what is stop out level? A stop-out level is the margin threshold at which a broker begins automatically closing one or more open positions because account equity has fallen too far relative to the margin required to keep those positions open. It acts as a last-resort risk control, but it does not guarantee a specific exit price or prevent all further losses.
If you trade CFDs or forex with leverage, understanding stop-out levels really matters. Adverse price movements can eat into your account equity through unrealised losses — and if your margin level falls far enough, your positions may be closed automatically, even if you haven't placed a closing order yourself.
Consider this your stop out level explained guide — covering how it works, how it differs from a margin call and how the Financial Conduct Authority's (FCA) margin close-out rules apply to UK retail clients.
Quick Takeaways
- A stop-out level is the margin threshold at which a broker begins closing open positions automatically.
- For UK retail clients covered by FCA rules, firms must close one or more relevant positions if net equity falls below 50% of the margin required to maintain open positions.
- The broker's terms and execution procedures determine which positions are closed and in what order. The regulatory rule does not require the largest losing position to be closed first.
- A close-out may be affected by slippage or market gaps, so an exact execution price is not guaranteed.
- Maintaining sufficient free margin can reduce the likelihood of an unexpected close-out during market volatility.
What Is a Stop-Out Level in Trading?
The stop out level meaning is straightforward: it's the margin level at which a broker begins closing open positions because there is no longer enough account equity relative to the margin required to maintain those positions.
Many trading platforms express margin level as:
Margin Level = (Equity / Used Margin) × 100
Where:
- Equity is the account balance adjusted for unrealised profits and losses on open positions.
- Used Margin is the amount of margin currently allocated to maintain open positions.
As unrealised losses increase, account equity falls. If used margin remains unchanged, this causes the margin level percentage to decline.
If the margin level reaches the applicable stop-out threshold, the broker may begin closing positions automatically. The precise calculation and close-out process depend on the broker, account type and regulatory regime.
For UK retail clients covered by FCA margin close-out rules, the relevant regulatory threshold is based on net equity falling below 50% of the margin requirement needed to maintain open positions.
Margin Call vs Stop-Out Level: What Is the Difference?
So what does stop out level mean compared to a margin call? They're related, but not the same thing.
A margin call generally refers to a warning or account condition indicating that available margin is becoming low. A stop-out goes further: the broker begins closing one or more positions to reduce the account's margin requirement.
Feature | Margin Call | Stop-Out Level |
|---|---|---|
Main Purpose | Warns that available margin is becoming low | Triggers the closing of one or more positions |
Threshold | Broker-specific and may vary by account | Depends on the broker and regulatory regime; FCA rules use a 50% account-level threshold for covered UK retail clients |
Broker Action | May issue an alert or apply account restrictions, depending on its terms | Begins closing one or more open positions |
Trader Action | May be able to reduce exposure or add funds before close-out | There may be little or no time to intervene once close-out begins |
Position Impact | Positions may remain open | One or more positions are closed |
There is no universal margin-call percentage that applies to every broker. A broker may set its own warning level above the stop-out threshold and may communicate it through its trading platform, email or another channel.
The important distinction is that a margin call generally acts as a warning, while a stop-out involves the actual closing of positions.
How Stop-Out Execution Works in Practice
When an account reaches its stop-out threshold, the broker's systems begin closing one or more positions according to the firm's terms and execution procedures.
The order in which positions are closed is not universal. Some brokers may close the largest losing position first, while others may use a different method. ESMA's margin close-out framework does not prescribe which positions must be closed or the order in which they must be closed.
Consider a simplified example:
- Account Balance: $1,000
- Used Margin: $200
- Stop-Out Level: 50%
Assuming the account uses a 50% stop-out threshold:
Stop-Out Equity Threshold = Used Margin × (Stop-Out Level / 100)
Stop-Out Equity Threshold = $200 × 0.50 = $100
If account equity falls to $100, the margin level would be:
Margin Level = ($100 / $200) × 100 = 50%
At $100 of equity, the margin level is 50%. If equity falls below this level, the FCA margin close-out requirement applies to covered UK retail accounts.
When a position is closed, some of the used margin is released. This reduces the amount of margin required to maintain the remaining positions and can raise the margin level.
The final close-out price depends on available market prices and the broker's execution policy. During fast-moving markets, major news releases or price gaps, a position may be closed at a different price from the level visible when the stop-out threshold was reached.
This difference is known as slippage. It means the actual execution price may differ from the expected price.
Using stop-loss orders on individual positions can help define an earlier exit point before the account reaches its stop-out threshold. However, a standard stop-loss does not guarantee a specific execution price and may also be affected by slippage or market gaps.
ESMA has recognised that market gaps can create situations in which margin close-outs cannot be executed without price slippage.
In forex trading, understanding pip value can also help traders estimate how a given price movement may affect unrealised profit or loss, account equity and, in turn, the margin level.
Regulatory Protection: The FCA 50% Margin Close-Out Rule
The Financial Conduct Authority (FCA) applies an account-level margin close-out requirement to restricted speculative investments offered to UK retail clients.
Under FCA COBS 22.5.13, a firm must ensure that a retail client's net equity does not fall below 50% of the margin required to maintain the client's open positions. If net equity falls below this threshold, the firm must close one or more relevant open positions as soon as market conditions allow.
This is an important distinction: reaching the 50% threshold does not guarantee that every position will be closed at an exact price or at precisely the moment the threshold is crossed. Market conditions can affect execution.
The FCA also requires firms to explain how their margin close-out level is calculated and triggered before a retail client opens their first relevant position.
The FCA framework covers restricted speculative investments, including leveraged CFDs and rolling spot forex contracts offered to retail clients.
In the EU, the European Securities and Markets Authority's (ESMA) original CFD intervention measures introduced a 50% account-level margin close-out threshold. Similar requirements now apply through national CFD product intervention measures across the EU. The framework does not prescribe which individual positions must be closed or the order in which they should be closed.
The margin close-out rule is separate from negative balance protection.
Under FCA rules, a retail client's liability for restricted speculative investments connected to the relevant trading account is limited to the funds in that account. This protection acts as a backstop when rapid market movements prevent the margin close-out mechanism from containing losses as intended.
Common Margin Mistakes That Increase Stop-Out Risk
A stop-out can result from a sharp market move, but how you manage your account can also affect how quickly your margin level falls.
- Using too much leverage: Large positions can consume a significant proportion of available margin, leaving less room for adverse price movements.
- Ignoring correlated exposure: Several positions in highly correlated currency pairs, indices or other markets may behave like one larger exposure when prices move in the same direction.
- Underestimating event risk: Major economic announcements can cause rapid price movements, wider spreads and slippage, which may reduce equity quickly.
- Treating the stop-out level as a stop-loss: Your broker's margin close-out mechanism is a last-resort account protection — it's not a substitute for managing the risk on your own individual positions.
Conclusion
A stop-out level is the point at which a broker begins closing positions because account equity has fallen too low relative to the margin required to keep those positions open. Unlike a margin call, which generally acts as an earlier warning or account condition, a stop-out results in actual position closures.
For UK retail clients covered by FCA rules, the regulatory margin close-out threshold is 50% of the margin required to maintain open positions. However, the rule does not guarantee an exact execution price or specify which position must be closed first.Keeping an eye on your account equity, used margin and position size can help you gauge how close you are to your stop-out level. Stop-loss orders can help you manage individual trade risk before you reach that point, though standard stop-loss orders can still be affected by slippage.
Understanding how leverage affects both required margin and potential losses is an important part of managing leveraged positions.

FAQ
What Is a Stop-Out Level in Forex Trading?
A stop-out level is the margin threshold at which a broker begins automatically closing one or more open positions. It is triggered when account equity falls too low relative to the margin required to maintain those positions. The exact close-out process depends on the broker, account type and applicable regulatory rules.
What Is the Difference Between a Margin Call and a Stop-Out Level?
A margin call generally warns that an account's available margin is becoming low, although the threshold and notification method vary between brokers. A stop-out occurs when the applicable margin threshold is reached and the broker begins closing one or more positions automatically. A margin warning may not always occur before a stop-out, particularly during rapid market movements or price gaps.
What Is the Regulatory Stop-Out Level Under FCA and ESMA Rules?
For UK retail clients covered by FCA rules, firms must close one or more relevant positions when account net equity falls below 50% of the margin required to maintain open positions, as soon as market conditions allow. In the EU, ESMA's original CFD intervention measures also introduced a 50% account-level margin close-out threshold. Similar requirements now apply through national CFD product intervention measures across the EU.
Can a Stop-Out Result in Losses Beyond the Funds in an Account?
Rapid price movements or market gaps can cause slippage, meaning positions may be closed at a worse price than expected. However, FCA negative balance protection limits a UK retail client's liability for covered leveraged products to the funds in the relevant trading account. Similar negative balance protection applies to retail CFD accounts covered by the EU's permanent national CFD intervention measures.
Which Trades Are Closed First During a Stop-Out?
There is no universal rule determining which position must be closed first during a stop-out. The order depends on the broker's terms and close-out procedures. A broker may close one or more positions to reduce the account's margin requirement. ESMA's margin close-out framework does not prescribe which positions must be closed or the order in which they are closed.
