Stop Loss Order: What It Is and How to Use It to Protect Your Trades

A stop loss order is an automatic instruction to close a trading position when the market reaches a specified price, helping limit the loss if the trade moves against you. It does not guarantee the exact exit price, however, because fast markets, slippage and price gaps can cause the actual fill to differ from the level you set.

That distinction is easy to miss.

A stop loss is not a force field around your trade. It is a risk-management instruction, and in leveraged markets, where a relatively small price move can have a much larger effect on your account, understanding exactly how it behaves matters.

Whether you trade forex, gold, indices, crypto CFDs or other leveraged products, the question is not simply whether you use a stop. It is where you put it, how much you risk behind it and what happens when the market moves faster than expected.

Key Takeaways

• A stop loss automatically triggers an order to close a position when a specified market level is reached.

• A standard stop loss does not guarantee the exact price at which your trade will be closed.

• The best stop placement depends on the trade setup, market structure and volatility, not simply on how much money you want to lose.

• Five practical approaches include percentage stops, support and resistance, ATR-based stops, moving-average stops and candlestick or chart-pattern stops.

• On MT5, a stop loss can be attached when opening a trade or added to an existing position, but you should understand how Bid, Ask, spread and trailing-stop mechanics affect the trigger.

What Is a Stop Loss Order?

So, what is a stop loss order in practical terms?

It is an instruction you attach to a position that tells the trading system to act if the market reaches a particular price.

If you are long, meaning you bought an asset or CFD expecting its price to rise, your stop normally sits below your entry. If the market falls to that level, the stop is triggered and an order is sent to close the position.

If you are short, your stop normally sits above your entry because you are expecting the price to fall. A rise to the stop level triggers an order to close the position.

Think of it less like a guarantee and more like a predefined line in the sand.

Position	Stop sits	Order triggered	Protects against
Long	Below entry	Sell order	Price falling
Short	Above entry	Buy order	Price rising

The key benefit is that you make the risk decision before the market starts arguing with you.

That matters because traders are very good at changing their minds when a losing position is already open.

“I’ll give it another 10 pips.”

“Maybe it will bounce.”

“I’ll move the stop just a little further.”

That little bit can become a very large loss.

How a Stop Loss Order Works

A stop loss does not normally execute as a limit order at the exact level you entered.

Instead, when the trigger condition is reached, the stop can convert into a market order, which is then filled at the next available price.

Suppose you buy EUR/USD at 1.0850 and place a stop at 1.0800.

That is a 50-pip stop.

If you trade one standard lot of EUR/USD, where one pip is approximately $10, your planned loss at that distance is around:

50 pips × $10 = $500

That is the planned risk before considering spread, commissions or slippage.

There is an important MT5 detail here. For a long position, the stop is triggered using the Bid price. For a short position, the Ask price is relevant. The spread therefore matters when deciding where your stop sits.

A stop that appears 10 pips away on a chart may not behave exactly as a beginner expects if they are looking at a different side of the market.

This is one reason why understanding how does stop loss work is more useful than simply knowing that a stop exists.

Stop Loss vs Stop-Out Level vs Margin Call

These three terms sound similar. They are not.

A stop loss is an order you set to manage the risk of an individual position.

A margin call is a warning or notification that your account’s available margin has fallen to a specified level.

A stop-out is a forced closure of positions by the broker when the account’s margin level reaches the applicable threshold.

You control the first one.

You do not control the second or third in the same way.

Mechanism	Who sets it?	Trigger	What closes?	Can you control it?
Stop loss	Trader	Specified market price	Your selected position	Yes
Margin call	Broker/platform terms	Margin falls to warning level	Usually no immediate forced closure	No
Stop-out	Broker/platform terms	Margin falls to stop-out level	Positions can be forcibly closed	No

For leveraged CFDs, this distinction becomes particularly important because your position can be closed by a stop-out even if you never placed a stop loss.

European retail CFD rules have included a margin close-out framework at 50% of required margin, but the exact terms applicable to an account depend on the jurisdiction and product.

For BitDelta Pro, the applicable stop-out and margin-call levels should be checked against the current account terms before publication or trading.

A stop loss and a stop-out are therefore not substitutes for one another. One is your risk-management instruction. The other is a broker-level protection mechanism triggered when your account no longer meets the required margin conditions.

Types of Stop Loss Orders

Not every stop loss behaves in exactly the same way.

Type	How it triggers	Exit price guaranteed?	Fill guaranteed?	Best for
Standard stop	Market reaches trigger level	No	Generally executes, but price can differ	Most routine risk management
Stop-limit	Stop triggers a limit order	Limit controls worst acceptable price	No	Traders willing to remain in the trade rather than accept a worse fill
Trailing stop	Stop follows favourable price movement	No	No exact-price guarantee	Protecting gains as a trade moves
Guaranteed stop	Designed to guarantee execution at specified level, subject to terms	Yes, where offered	Yes, subject to provider terms	Specific gap-sensitive situations
Mental stop	Trader manually decides when to exit	No	No	Experienced discretionary traders, with discipline

A sell stop order is generally used to trigger a sell when the market falls to a specified level, while a buy stop order is used above the current market to trigger a buy when price rises to that level.

Guaranteed stop-loss orders, or GSLOs, can carry a premium and are not necessarily available on every platform or account. Availability and pricing should be confirmed before publication.

For the broader MT5 order taxonomy, see our MT5 order types guide.

Stop Loss vs Stop Limit

This distinction is particularly important during fast markets.

Suppose you are long and place a stop at 1.2500, with a stop-limit order allowing execution down to 1.2490.

If the market trades through 1.2500 and then gaps directly to 1.2450, your limit condition may prevent the order from filling.

That sounds safer because you have controlled the worst acceptable price.

But there is a catch.

You may still be holding the position.

A standard stop loss prioritises getting you out. A stop-limit prioritises controlling the minimum acceptable execution price.

Stop Loss	Stop Limit
Prioritises execution	Prioritises price control
Can suffer slippage	Can remain unfilled
Useful when exiting is the priority	Useful when avoiding an unacceptable fill is the priority
More exposed to price gaps through the trigger	More exposed to remaining in the trade

So when people search for stop loss vs stop limit, the real question is not which one is universally better. It is which risk you would rather accept.

Trailing Stop Loss

A trailing stop loss moves with the market when your position moves in your favour.

Suppose you buy an asset at $100 and set a 5% trailing stop.

If the price rises to $109, the trailing stop would sit around:

$109 × 95% = $103.55

The market has therefore moved $9 in your favour while the trailing level has moved above your original entry.

A trailing stop can also be moved manually to break-even, creating what traders often call a breakeven stop.

There is an important platform detail with MT5: the native trailing stop is handled by the client terminal. If the terminal is closed, the last calculated stop level remains in place, but the trailing mechanism itself is no longer actively updating until the terminal is running again.

A trailing stop loss vs trailing stop limit comparison follows the same basic trade-off as standard stop and stop-limit orders: one prioritises getting out, while the other adds price constraints that can leave the position open.

Benefits of Using a Stop Loss Order

A stop loss is not exciting.

That is precisely why traders sometimes neglect it.

But the stop loss order benefits are practical rather than glamorous.

1. It Caps the Planned Loss

If your EUR/USD trade has a 40-pip stop and your position size means each pip is worth $5, your planned risk is around $200 before costs and slippage.

2. It Removes an Emotional Decision

You decide the invalidation level before the position starts moving against you, rather than negotiating with yourself after the loss appears.

3. It Makes Position Sizing Possible

Once you know the distance between entry and stop, you can calculate how large your position should be.

4. It Protects You While You Are Away

Markets continue moving while you are working, sleeping or simply not watching the screen. A predefined stop provides an automated risk-control mechanism.

5. It Can Protect Open Profits

A trailing stop can move upward with a long position or downward with a short position, allowing some of the unrealised profit to remain protected.

6. It Defines Risk Before the Trade

Knowing the stop and potential target allows you to assess the trade’s risk-to-reward ratio before committing capital.

That last point is particularly useful because a trade should not become a risk-management problem only after it has already gone wrong.

Risks and Limitations of Stop Loss Orders

A stop loss reduces one type of risk.

It does not eliminate market risk.

Risk	What Happens	Example	How to Reduce It
Slippage	Position closes at a different price from the stop	Stop at 1.0800, fill at 1.0797	Avoid excessive leverage and understand execution conditions
Gapping	Market jumps over your stop	Weekend gap from 1.0805 to 1.0760	Avoid oversized positions through known gap risks
Whipsaw	Price briefly hits stop before reversing	EUR/USD drops 15 pips, triggers stop, then rallies	Place stops beyond meaningful market structure
Stop hunting	Price briefly moves around obvious levels	Stop clustered below a round-number low	Avoid mechanically placing stops at obvious levels
Spread widening	Bid/Ask difference expands	News or rollover widens spread enough to trigger stop	Understand spread conditions and trading sessions

The most important point is simple:

A standard stop loss does not guarantee your exit price.

If the market moves quickly, the available price when the stop is executed may be worse than the level you specified.

Weekend gaps are an obvious example. If a market closes at one price on Friday and reopens significantly lower on Monday, there may simply be no tradable price at your stop.

This is slippage and gapping, not the stop “failing”.

For more detail, see our guide to slippage in trading.

How to Use a Stop Loss Order: 5 Ways to Set Your Stop

There is no universal best stop loss strategy.

The useful rule is simpler:

Put the stop where the trade idea is invalidated, then size the position around that stop.

Not the other way around.

1. Percentage Stop

A percentage stop places the stop a fixed percentage away from the entry price.

For example, if a share trades at $100 and you use a 7% stop, the stop sits at $93.

William O’Neil’s well-known 7–8% rule is associated with this approach in share trading, but applying the same distance mechanically to leveraged forex or CFD positions can produce an entirely different risk profile.

Also, do not confuse a percentage stop distance with a percentage account risk.

A trader risking 1% of a $10,000 account is risking $100. That does not mean the stop should automatically be 1% away from the entry.

The position size connects the two.

2. Support and Resistance Stop

This approach uses market structure.

For a long position, the stop can sit below a relevant swing low or support zone. For a short position, it can sit above a swing high or resistance area.

Suppose EUR/USD breaks above resistance at 1.0850 and you enter at 1.0860. If the previous swing low sits at 1.0820, a stop slightly below that structure may make more sense than an arbitrary 10-pip stop.

Give the market some room.

Placing stops at highly obvious round numbers can also make them vulnerable to brief moves through those levels, particularly in volatile conditions.

3. Volatility Stop Using ATR

A fixed stop can behave very differently in quiet and volatile markets.

The Average True Range (ATR) provides a way to account for that changing volatility.

A simplified formula is:

Stop distance = ATR × multiplier

Suppose EUR/USD has a 14-period ATR of 70 pips and you use a 1.5× multiplier:

70 × 1.5 = 105 pips

A volatility-based stop would therefore sit around 105 pips from the entry, depending on the direction of the trade.

A fixed 50-pip stop might be generous in a quiet market but extremely tight during a high-volatility session.

ATR does not tell you where the trade idea is wrong. It tells you how much the market is currently moving, which can help you avoid placing a stop where normal price noise is likely to trigger it.

4. Moving Average or Indicator Stop

Some traders use a moving average as a dynamic exit level.

For example, a trend trader might enter a long position and decide that a sustained close below the 20 EMA or 50 EMA invalidates the setup.

The important word is close.

If you wait for a candle to close below the moving average before exiting, that is not the same as having an automatically triggered stop at the moving average. Unless the order is automated, it is effectively a manual or mental stop.

That creates execution and discipline risk.

5. Candlestick and Chart-Pattern Stop

Chart patterns provide another way to define invalidation.

If you enter after a bullish hammer, the stop might sit below the hammer’s low. If you enter a short position following a bearish shooting star, the stop could sit above the candle’s high.

The logic is straightforward: if price breaks the level that invalidates the pattern, the original trade idea may no longer make sense.

The stop therefore comes from the setup, rather than from an arbitrary dollar amount.

For more on price-action setups, see our candlestick patterns guide.

Position Sizing: Turning Your Stop Into a Risk Number

A stop only becomes meaningful when you connect it to position size.

A simple position-sizing formula is:

Position size = (Account × Risk %) ÷ (Stop distance × Pip value)

Consider a $10,000 account where you are willing to risk 1%:

$10,000 × 1% = $100

Now assume your EUR/USD stop is 40 pips and the pip value at the chosen position size is $10 per standard lot.

The required position size is:

$100 ÷ (40 × $10) = 0.25 lots

So a 0.25-lot position with a 40-pip stop gives approximately $100 of planned risk before transaction costs and slippage.

This is where leverage is often misunderstood.

Using 500× leverage does not mean you should risk 500 times more money. Leverage changes the margin required to open the position. Your stop distance and position size determine the planned loss if the stop is triggered.

In other words, choose the stop from the trade idea, then choose the position size from the risk limit.

Do not choose the stop based on how much money you happened to want to risk.

Combining Stop Loss and Take Profit

Stop loss and take profit work together.

Suppose you risk 40 pips and target 80 pips.

That gives you a 1:2 risk-to-reward ratio.

If you win 1 trade and lose 2, you would have:

1 × 80 pips = +80

2 × 40 pips = -80

Ignoring costs, that is approximately break-even.

That means a 1:2 setup has a theoretical break-even win rate of around 33.3% before spread, commission and slippage.

The ratio itself does not make a trade profitable. A poor strategy can lose money with a 1:5 target if it rarely reaches the target.

The point is to know what you are risking before you enter.

How to Set a Stop Loss on MT5 and BitDelta Terminal

On MetaTrader 5, you can generally add a stop loss when opening a position or attach one to an existing trade.

When Opening a New Trade

1. Open the New Order window.

1. Select the instrument and order type.

1. Enter your position size.

1. Set the S/L field to your chosen stop price.

1. Set your take-profit level if required.

1. Review the trade and submit the order.

Adding a Stop to an Existing Position

1. Locate the open position in the Toolbox/Trade section.

1. Right-click the position.

1. Select Modify or Delete Order.

1. Enter the required stop-loss level.

1. Confirm the modification.

Depending on your MT5 setup, you can also drag the stop-loss line directly on the chart.

Adding a Trailing Stop

Right-click the open position and select the relevant Trailing Stop option, then choose the required distance.

Remember the MT5 client-side limitation discussed earlier: the trailing mechanism relies on the running terminal, while the latest stop level remains in place if the terminal is closed.

Pending Orders and Expiry

For applicable pending orders, check the expiry/time-in-force settings. GTC, or Good ‘Til Cancelled, means the order remains active until it is cancelled or triggered, subject to the platform’s rules.

For BitDelta Terminal, the exact stop-loss and trailing-stop workflow should be confirmed against the current platform functionality and screenshots before publication, as the supplied brief specifically flags native trailing-stop support as requiring client confirmation.

You can also practise placing and modifying stops on a demo account before risking live capital.

Common Stop Loss Mistakes to Avoid

Mistake	Fix
Setting the stop too tightly	Give the trade enough room for normal volatility
Moving the stop further away after entry	Define the maximum risk before entering and respect it
Placing stops exactly at obvious round numbers	Consider nearby market structure and spread conditions
Ignoring Bid and Ask	Understand which side of the market triggers your stop
Holding without protection through major news	Decide beforehand whether the trade should remain open
Choosing position size first	Determine the stop from the chart, then size the position around the risk

One of the worst habits in stop loss trading is moving the stop further away because the market is approaching it.

The reasoning usually sounds sensible in the moment.

“Just another 10 pips.”

But the trade has not become better because the stop moved. The trader has simply increased the amount they are willing to lose.

A stop should be allowed to do its job.

FAQs

What Is the 7% Rule for Stop Loss?

The 7% rule generally refers to the practice of cutting a losing share position when it falls around 7% below the entry price, a rule associated with William O’Neil’s trading methodology. It is not a universal rule and should not be applied mechanically to leveraged forex or CFD trading, where volatility and position sizing can be very different.

What Is the Golden Rule for Stop Loss?

A useful golden rule is simple: never widen your stop just because the trade is losing. The stop should be positioned where your original trade idea becomes invalid. If the market reaches that point, accept the predefined loss rather than changing the rules after the position has gone against you.

What’s the Difference Between a Stop Limit and a Stop Order?

A standard stop order generally becomes a market order once its trigger level is reached, prioritising execution but exposing you to slippage. A stop-limit order adds a limit price, giving you more control over the worst acceptable fill but creating the possibility that the order will not execute at all if the market moves beyond the limit.

Does a Stop Loss Guarantee My Exit Price?

No. A standard stop loss does not guarantee the exact price at which your position will close. Once triggered, the order may execute at the next available price, which can be different because of slippage, fast markets, low liquidity or price gaps. A stop controls the trigger level, not necessarily the final execution price.

Can a Stop Loss Trigger Over the Weekend?

Yes. If the market reopens at a price beyond your stop after a weekend gap, the position can be closed at the next available price rather than at the exact stop level. This is why traders holding leveraged positions through weekends need to consider gap risk and avoid assuming that a stop guarantees a particular exit price.

Where Should I Put My Stop Loss?

Put the stop where the trade idea is invalidated rather than choosing a distance simply because it produces a preferred dollar loss. Depending on the strategy, that may be beyond a swing high or low, support or resistance, an ATR-based volatility level, a moving average or a chart-pattern invalidation point.

Is Stop Loss Hunting Real?

Price can move through obvious support, resistance and clustered order levels before reversing, but that does not automatically mean a broker is deliberately hunting your stop. Stops placed around highly visible levels can naturally become part of market liquidity. Using meaningful market structure, appropriate position sizing and a sensible volatility buffer can reduce the risk of being stopped by ordinary market noise.

Practise Your Stop Loss Strategy on Demo

A stop loss is only useful if you understand what it does before you need it.

Test different placement methods on a demo account. Compare a structure-based stop with an ATR stop. Watch what happens around major news, during volatile sessions and when spreads widen. Then review whether your position size still makes sense once the stop distance changes.

Most importantly, remember what a stop loss can and cannot do. It can automate your exit decision and help define risk. It cannot guarantee your price or make a bad trade good.

And it certainly cannot remove the risk that comes with leveraged trading.
