Stop-loss order

What a stop-loss order means

A stop-loss order is an instruction to close a position automatically when the market reaches a price you choose. If you hold a long position, the stop sits below the current price. If you are short, it sits above. The purpose is to put a ceiling on how much a single trade can lose, so that a bad outcome is limited to a size you decided in advance.

The order is stored with your broker or on the exchange and does not require you to watch the screen. When the market touches the stop price, the order is triggered. In the standard version it then becomes a market order and closes the position at the next available price.

Stop-losses are used by active traders in forex, CFDs, stocks, futures and options, and also by longer-term investors who want a floor under a holding. They are one of the basic tools of risk management, alongside position sizing and diversification.

How it works

The mechanics follow a short sequence.

1. You open a position and choose a stop price, either as a price level or as a distance in pips or points.
2. The broker monitors the market. Depending on the platform, the trigger can be based on the bid, the ask, the last traded price or a mid price. For a long CFD position the stop usually watches the bid, because that is the price at which you could sell.
3. When the trigger price is touched, the stop order becomes a market order.
4. The position closes at the best available price. This is usually close to your stop but can be worse during fast markets or gaps. This difference is called slippage.

There are several types. A standard stop is the one described above. A guaranteed stop, offered by some brokers in some regions for an extra premium or wider spread, closes at exactly your level even in a gap. A trailing stop follows the price at a fixed distance when the trade moves in your favor, locking in part of the gain. A stop-limit adds a price cap but may not fill.

Where to place the stop is a separate decision. Traders may use a fixed percentage, a multiple of average true range (a volatility measure), or a technical level such as just beyond a recent swing low.

A worked example

The following numbers are illustrative. You buy EUR/USD at 1.0850 and decide that you will accept a loss of 40 pips. Your account is 5,000 USD and you want to risk 1% of it, which is 50 USD.

• Entry: 1.0850
• Stop-loss: 1.0810 (40 pips below)
• Maximum risk: 1% × 5,000 = 50 USD
• Value of one pip for a standard lot (100,000 units) is about 10 USD, so for position size x lots: 40 pips × 10 USD × x = 50 USD
• x = 50 ÷ 400 = 0.125 lots, which rounds down to 0.12 lots

If the market falls to 1.0810, the stop triggers and the position closes with a loss of about 40 × 10 × 0.12 = 48 USD, plus spread. If the market gaps to 1.0795 over a weekend, the fill happens near 1.0795 and the loss is 55 pips, about 66 USD, larger than planned. A guaranteed stop would have closed at 1.0810.

Why it matters

A stop-loss turns an open-ended risk into a defined one, at least in normal conditions. That helps with discipline: you decide the exit when you are calm, not in the middle of a drawdown when emotions are strong. It also makes position sizing possible, because the distance to the stop is an input to how many units you can afford to trade.

For leveraged products the stop is especially relevant, because small price changes can mean large changes in account equity. Brokers also differ in how they execute stops, what fees apply to guaranteed stops, and whether the platform shows stop levels to others.

How to use it in practice

1. Decide the stop level before you enter the trade, based on the market structure or volatility and not on how much you hope to lose.
2. Calculate the position size from the stop distance and the amount you are willing to risk.
3. Check the trigger price type your broker uses and compare it with the spread, so the stop does not trigger on a routine spread widening.
4. Allow for normal volatility. A stop placed inside the usual noise is likely to trigger without any real change of view.
5. Check whether a guaranteed stop is offered, what it costs and whether it is available for your account type.
6. Review the order at week end and before known events such as central bank decisions and earnings releases.
7. Never move a stop further away just to avoid a loss.

Common mistakes and misconceptions

• Assuming a stop guarantees the exit price. A standard stop guarantees only that an order is sent when the level is hit.
• Placing stops at obvious round numbers where many other orders cluster and price often spikes.
• Setting a stop so tight that ordinary fluctuation closes the trade.
• Leaving out the stop because "I will watch it", which fails during sleep, outages or sudden news.
• Removing or widening the stop after the trade moves against you.
• Ignoring the spread, which can trigger a stop on the bid even when the chart price has not touched the level.

Risks and limitations

Stops can slip. In a gap, trading halt or very illiquid market, execution may be far from the chosen level, and on some leveraged products the loss can exceed the deposit unless negative balance protection applies. Stops can be triggered by brief spikes that reverse right afterwards, leaving you out of a trade that would later have recovered. A stop-loss does not remove market risk; it only manages it, and it does not suit every strategy. Rules and the availability of guaranteed stops differ by jurisdiction.

How Brokeli looks at it

We check which stop types a broker supports, whether guaranteed stops exist and under what conditions, and how the platform describes execution during gaps. These details are recorded from the broker's own documents in our published research snapshots. We treat stop handling as part of execution quality and risk protection rather than as a feature to rank by itself.
