Stop loss orders are a trader’s best friend. Most new traders think that if they can learn the newest / best / most accurate way of forecasting the market movements they will have the key to untold riches in the market. After trading for a while these new traders are inevitably disappointed with the results of this search for the Holy Grail.

Why? Because they have not learned to limit their losses – they need stop loss orders!

Understanding the trading profitability equation shows that limiting losses and protecting capital is the key to first surviving and then trading profitably. No trader will remain consistently profitable until they learn how to control their losses. This is true whether you trade Forex, Futures, Bonds or the Stockmarket.

A Stop Loss is the most useful tool to limit your trading losses

Having an automatic mechanism to limit your losses on every single trade will help prevent one trade from becoming a monster loser (or many trades becoming large losses) which eats into your trading profits. The stop loss order is this mechanism.

If you losing trades are too big,
your winners can’t overcome them!

What Is A Stop Loss Order?

A stop loss order is an order that you place when you open a trade which will automatically close your trade if it moves against you by a certain amount.

For example, lets say you are buying ABC stock at $50 per share and you think that if it drops to $45 per share you must be wrong on the trade and you want to get out. If this was the case you would place a stop loss at $45 so that if the price dropped that far your order would be executed and you would be out of the market.

A stop loss gets you out of a trade
if it moves too much against you

The stop loss order remains dormant until the stop price is hit. At this time it is placed into the market as a market order and will be executed at the prevailing price.

Benefits Of Stop Losses:

The main benefit of stop loss orders is that they allow you to predetermine the level at which you want to exit the trade. If that level is hit, you exit! This takes the emotion and second guessing and hope out of the exit. If the level is hit you exit.

One of the biggest mistakes traders make is holding onto a losing position hoping that it will turn around…when it doesn’t the results can be disastrous!

Losing 5 or 10 times what you intended to risk on a trade is
a sure path to ruin. A stop loss can help prevent this!

As a system trader I don’t care what any one of my positions does. I know that if I design a trading system for the Stockmarket, Futures or Forex which cuts my losses and lets my profits run then I have a good chance of a profitable trading system. Executing this system consistently over many many trades generates the profits I am looking for.

Every trading system that I design has stop losses. This ensures several things:

  • I know my initial risk on each trade
  • If my stop loss is hit I exit – even if I am not monitoring the market
  • I avoid the fatal psychological mistake of hoping a losing trade will turn around
  • My big winning trades are not overshadowed by large losses

Drawbacks Of Using A Stop Loss:

There are two drawbacks of using stop losses that traders should be aware of. Neither in my opinion warrants not using stops because the benefits are so great.

The first drawback is that an intraday volatile spike in price against your position could stop you out during the trading day only to reverse and end up back where it was or higher.

This can be immensely frustrating and makes it very tempting to stop using stop loss orders. What you probably don’t realize though is that this is just a small price to pay for all the times that your stop loss orders get you out and the market keeps moving against you.

Trading profitability is not about milking the most from any one trade. It is about designing a trading system that fits you, has a positive expectancy and executing it consistently over time. So my suggestion is not to focus on the few times the stops force you out early, but focus on the design of your trading system, including stops to limit your worst case loss.

The second drawback of stop losses is that they can incur a lot of slippage if you trade thin or illiquid markets.

Slippage is a fact of life in trading, however you can mitigate it by trading highly liquid instruments. Even though illiquid instruments can give you a lot of slippage with stop loss orders, they can move even further against you if you don’t get out when you should.

My personal opinion is that it is better to get out with some slippage than to stay in and risk the trade moving even further against you, but that is just my opinion – you need to design your system based on your objectives and beliefs to fit you.

Stop Losses are a very important consideration
for all traders – Ignore them at your peril!

Conclusion:

Protecting your trading capital by placing a stop loss on every trade is a great way of introducing discipline into your trading. It helps ensure you exit small losing trades before they become big losing trades. It also eliminates one of the big psychological problems new traders have – Taking Losses.

Stop loss orders take you out of losing trades
at a small loss and protect your capital

Frequently Asked Questions about Stop Loss Order

What is a stop-loss order?

A stop-loss order is a crucial tool in trading, designed to limit potential losses on a trade. Here’s how it works:

  • Definition: A stop-loss order is an order you place with your broker to sell a stock if it falls to a certain price. This order remains inactive until the stock hits the specified stop price, at which point it becomes a market order and is executed at the best available price .
  • Purpose: The primary goal of a stop-loss order is to protect your trading capital by automatically closing a trade if it moves against you by a predetermined amount. This helps prevent small losses from becoming large ones, which is essential for long-term trading success .
  • Benefits: Stop-loss orders take the emotion out of trading decisions, ensuring you exit a losing trade at a small loss rather than holding on and hoping for a reversal. This discipline is vital for maintaining a profitable trading strategy .
  • Drawbacks: One potential drawback is slippage, where the execution price may differ from the stop price due to market volatility. However, the benefits of protecting your capital generally outweigh this risk .

Incorporating stop-loss orders into your trading system is a smart way to manage risk and maintain discipline.

What is the best stop-loss strategy?

The best stop-loss strategy often depends on your trading style and the specific market conditions you’re dealing with. However, a volatility-based stop-loss using the Average True Range (ATR) is generally a solid choice. Here’s why:

  • Adaptability: ATR-based stop-losses adjust to the volatility of the stock. If a stock is more volatile, the stop-loss is set wider, and if it’s less volatile, the stop-loss is narrower. This adaptability helps prevent getting stopped out by normal market fluctuations .
  • Objective and Backtestable: Unlike subjective methods like support and resistance, ATR-based stops can be rigorously backtested, allowing you to build confidence in your system’s performance .
  • Consistency Across Markets: You can apply the same ATR-based rule across different stocks and markets, ensuring a consistent approach to risk management .
  • Avoiding Noise: By setting the stop-loss at a multiple of the ATR, you reduce the likelihood of being stopped out by random market noise, which is a common issue with overly tight stops .

While ATR-based stops are highly effective, it’s crucial to backtest and ensure they fit your trading strategy and risk tolerance.

What is the difference between a limit order and a stop-loss order?

The difference between a limit order and a stop-loss order is primarily in their purpose and execution:

  • Limit Order: This order type is used to buy or sell a stock at a specific price or better. For a buy limit order, you set the maximum price you’re willing to pay, and for a sell limit order, you set the minimum price you’re willing to accept. Limit orders are great for ensuring you get the price you want, but they might not get filled if the market price doesn’t reach your specified limit .
  • Stop-Loss Order: This is a type of order designed to limit an investor’s loss on a position. It’s set at a specific price, and if the market hits that price, the stop-loss order becomes a market order and is executed at the best available price. The main goal is to protect your capital by automatically selling a stock if it falls to a certain level, thus preventing further losses .

In essence, limit orders are about price control and getting the best deal, while stop-loss orders are about risk management and protecting against significant losses. 

Why are stop losses a bad idea?

Stop losses aren’t inherently a bad idea, in fact, they’re crucial for risk management. However, there are some nuances to consider that might make them seem problematic in certain situations:

  • Slippage: When a stop-loss order is triggered, it becomes a market order, which means it will be executed at the best available price. In volatile markets, this can lead to slippage, where the execution price is worse than expected .
  • Intraday Noise: Markets can be noisy, with price spikes that might trigger your stop-loss prematurely. This can result in being stopped out of a position only to see the market recover shortly after, which can be frustrating .
  • Fear and Greed: Stop-loss orders can sometimes get executed at the point of maximum fear, especially during intraday volatility. This can mean exiting a trade at a low point, missing out on potential recovery .
  • Backtesting Considerations: It’s essential to backtest your trading system with different stop-loss strategies to see what works best. Sometimes, alternative approaches like a next bar on open stop can yield better results, as I’ve found in my own trading systems .

While stop losses are vital for protecting your capital, it’s important to understand these potential drawbacks and adjust your strategy accordingly.

How many days is a stop-loss order valid?

The validity of a stop-loss order can vary based on how you set it up. In some trading platforms, you can specify the duration for which the stop-loss order remains active. For instance, you might set it to be valid for a certain number of days, or you could choose to have it remain active indefinitely until the trade is closed or the stop-loss is triggered.

In the context of using the ApplyStop function in Amibroker, you can specify how long a stop-loss remains active. You might set it to be active for a specific number of days, like ten days, or you could set it to remain active for the entire life of the trade by using a setting that allows it to go on indefinitely .

Ultimately, the duration of a stop-loss order depends on your trading strategy and the settings you choose in your trading platform.

When should I use stop-loss?

Using stop-loss orders is a key part of risk management in trading, and they should be used thoughtfully based on your trading strategy and risk tolerance. Here are some scenarios where using a stop-loss is particularly beneficial:

  • Protecting Capital: If you’re concerned about limiting potential losses on a trade, a stop-loss can automatically close your position if the market moves against you, preventing further losses .
  • Maintaining Discipline: For traders who struggle with emotional decision-making, stop-loss orders can enforce discipline by ensuring you exit losing trades before they become large losses .
  • Volatile Markets: In highly volatile markets, stop-loss orders can help manage risk by getting you out of trades that move sharply against you, which is crucial to avoid catastrophic losses .
  • When Backtesting Supports It: If your trading system backtests better with stop-losses, it’s a good indication that they should be part of your strategy. Always backtest to ensure your approach is optimal .
  • When You’re Not Actively Monitoring: If you can’t monitor your trades constantly, stop-loss orders can act as a safety net, ensuring you don’t suffer large losses due to unforeseen market movements .

Ultimately, the decision to use stop-losses should be based on your trading system’s performance and your personal risk management preferences.

How to execute a stop-loss order?

Executing a stop-loss order involves a few key steps, and it’s important to understand how it functions within your trading platform. Here’s a straightforward guide:

  • Determine Your Stop-Loss Level: Decide the price at which you want to exit the trade if it moves against you. This could be based on a percentage of your entry price, a specific dollar amount, or a volatility measure like the Average True Range (ATR) .
  • Enter the Order: In your trading platform, select the option to place a stop-loss order. You’ll need to specify the stop price, which is the trigger point for your order to become active .
  • Choose the Order Type: Decide whether you want a traditional stop-loss order, which becomes a market order when triggered, or a stop-limit order, which becomes a limit order with a specified price limit to control slippage .
  • Set the Duration: Specify how long you want the stop-loss order to remain active. This could be for a day, until canceled, or for a specific number of days, depending on your strategy and platform capabilities .
  • Monitor and Adjust: Keep an eye on your trades and adjust your stop-loss levels as needed, especially if the market conditions change or if you’re trailing your stop to lock in profits .

Executing stop-loss orders effectively is crucial for managing risk and protecting your capital. 

How long does a stop-loss order last?

The duration of a stop-loss order can vary based on how you set it up in your trading platform. Typically, you have a couple of options:

  • Good Till Canceled (GTC): This means the stop-loss order remains active until you manually cancel it or it gets triggered. It’s a common choice for traders who want their stop-loss to protect their position for the entire duration of the trade .
  • Good for Day: This option means the stop-loss order is only valid for the trading day on which it was placed. If it’s not triggered by the end of the day, it will expire and you’ll need to set it again for the next day if you still want that protection .

Choosing the right duration depends on your trading strategy and how actively you manage your trades.

Can a stop-loss order be cancelled?

Absolutely, a stop-loss order can be canceled. If you decide that you no longer want the stop-loss order to be active, you can go into your trading platform and cancel it manually. This is particularly useful if market conditions change or if you decide to adjust your trading strategy.

For instance, if you’re using Interactive Brokers’ Trader Workstation, you can manage your orders directly through the platform. You have the flexibility to cancel a stop-loss order at any time before it’s triggered. This allows you to adapt to changing market conditions or new insights that might affect your trading decisions .

It’s always a good idea to regularly review your active orders to ensure they align with your current trading strategy and market outlook.

Is stop-loss valid for one day?

A stop-loss order isn’t typically set to be valid for just one day. Generally, when you place a stop-loss, you want it to be “Good Till Canceled” (GTC). This means it stays active until it’s either triggered or you decide to cancel it manually. The idea is to have that safety net in place for the entire duration of your trade, not just for a single day .

If you were to set a stop-loss as “Good for Day,” it would expire at the end of the trading day if not triggered, which isn’t usually what traders want. You want that protection to be there consistently, especially if you’re not monitoring the market constantly. So, it’s crucial to ensure your stop-loss is set as GTC to maintain that ongoing protection .

Can a stop-loss order fail?

A stop-loss order can indeed fail to execute as expected, and there are a few reasons why this might happen:

  • Slippage: When a stop-loss is triggered, it turns into a market order. If the market is moving quickly, the order might be filled at a price significantly different from the stop-loss level you set. This is especially common in volatile markets or during significant news events .
  • Gaps: If the market opens at a price significantly lower than your stop-loss level, your order will be executed at the opening price, not your stop-loss price. This can result in a larger loss than anticipated .
  • Intraday Noise: Sometimes, a temporary price spike can trigger your stop-loss, only for the price to quickly recover. This can be frustrating as it takes you out of a position prematurely .
  • Execution Issues: In rare cases, technical issues with your broker or trading platform can prevent a stop-loss from executing properly.

It’s crucial to understand these risks and consider them when setting stop-loss orders. Backtesting your strategy can help you understand how these factors might impact your trades and adjust your approach accordingly .

Which is better, stop-loss or stop-limit?

The choice between a stop-loss and a stop-limit order really depends on your trading strategy and risk tolerance. Here’s a breakdown to help you decide:

  • Stop-Loss Order: This order type is triggered when the price hits your specified level, and it becomes a market order. The main advantage is that it provides certainty of execution, meaning you’ll definitely exit the trade if the stop level is hit. However, it can suffer from slippage, especially in fast-moving or illiquid markets, where the execution price might be worse than expected .
  • Stop-Limit Order: This combines a stop order with a limit order. When the stop price is hit, it becomes a limit order, which will only execute at your specified price or better. This helps control slippage, but there’s a risk that the order won’t be executed if the market moves past your limit price without filling your order. This could leave you exposed to further losses if the market continues to move against you .

In general, if you’re prioritizing getting out of a trade no matter what, a stop-loss order might be more suitable. But if you’re concerned about slippage and want more control over the execution price, a stop-limit order could be the way to go. It’s crucial to backtest and see which fits your trading style better .

Is a stop-loss guaranteed?

A stop-loss order isn’t guaranteed to execute at your specified price due to slippage. When a stop-loss is triggered, it becomes a market order, which means it will be filled at the best available price in the market at that time. If the market is moving quickly or is illiquid, you might get executed at a price worse than your stop-loss level, which is known as slippage .

For instance, if there’s a sudden price drop, your stop-loss might be triggered, but the execution could occur at a lower price than you anticipated. This is particularly common during volatile market conditions or when there’s a gap in prices between trading sessions .

To mitigate this, some traders use stop-limit orders, which provide more control over the execution price but come with the risk that the order might not be filled if the market moves past the limit price without executing . It’s crucial to understand these dynamics and incorporate them into your trading strategy.

What are the disadvantages of a stop-loss order?

Stop-loss orders, while essential for risk management, do come with a few disadvantages:

  • Slippage: When a stop-loss is triggered, it becomes a market order. This means it will be executed at the best available price, which can be significantly different from your stop-loss level, especially in fast-moving or illiquid markets. This slippage can erode your profitability if not managed carefully .
  • Gaps: If the market opens at a price significantly lower than your stop-loss level, your order will be executed at the opening price, not your stop-loss price. This can result in a larger loss than anticipated .
  • Intraday Noise: Sometimes, a temporary price spike can trigger your stop-loss, only for the price to quickly recover. This can be frustrating as it takes you out of a position prematurely .
  • Market Volatility: In highly volatile markets, stop-loss orders can be triggered frequently, leading to multiple small losses that can add up over time.

Despite these drawbacks, stop-loss orders are crucial for protecting your trading capital and ensuring discipline in your trading strategy. It’s important to weigh these disadvantages against the benefits and adjust your strategy accordingly . 

What does 5% stop-loss mean?

A 5% stop-loss means that you set your stop-loss order to trigger if the stock price drops by 5% from your entry price. This is a way to limit your potential loss on a trade to a manageable level. For example, if you buy a stock at $100, a 5% stop-loss would be set at $95. If the stock price falls to $95, your stop-loss order would be triggered, and you’d exit the trade to prevent further losses .

Using a percentage-based stop-loss is a straightforward method to manage risk, but it’s important to remember that it doesn’t adapt to different levels of volatility. In highly volatile markets, a 5% stop-loss might be too tight, causing you to exit trades prematurely. Conversely, in less volatile markets, it might be too loose, exposing you to larger losses than necessary .

It’s crucial to consider the market conditions and your trading strategy when setting a stop-loss percentage. Backtesting your strategy can help you determine the optimal stop-loss level for your specific approach.

When to put stop-loss order?

Placing a stop-loss order is a crucial part of managing risk in your trading strategy. Here are some guidelines on when to put a stop-loss order:

  • Immediately After Entering a Trade: It’s generally wise to set your stop-loss as soon as you enter a trade. This helps protect your capital from unexpected market movements and ensures you have a predefined exit strategy .
  • Based on Chart Patterns: You can set a stop-loss just below a recent support level or a significant chart pattern. This approach uses technical analysis to determine logical points where the trade might be invalidated .
  • Volatility Considerations: If you’re using a volatility-based stop-loss, consider the Average True Range (ATR) to determine how far the price typically moves. This helps you avoid getting stopped out by normal market fluctuations .
  • Market Conditions: During volatile or uncertain market conditions, you might want to adjust your stop-loss levels to account for increased price swings. This can help prevent premature exits due to temporary price spikes .
  • Risk Tolerance: Your personal risk tolerance should guide where you place your stop-loss. Determine how much of your capital you’re willing to risk on a single trade and set your stop-loss accordingly .

Remember, the key is to have an objective exit rule that aligns with your trading strategy and risk management plan.

What happens when a stop-loss order is triggered?

When a stop-loss order is triggered, it converts into a market order. This means it will be executed at the best available price in the market at that time. The primary purpose of a stop-loss is to limit your losses by automatically selling your position if the price moves against you to a predetermined level .

However, it’s important to be aware of slippage. Since the stop-loss becomes a market order, the execution price might differ from your stop-loss level, especially in fast-moving or illiquid markets. This can result in a sale price that’s worse than expected, which is a common risk associated with stop-loss orders .

For example, if you set a stop-loss at $49 and the price drops to that level, your order is triggered and becomes a market order. If there are enough buyers at $49, your order will be filled at that price. But if there aren’t enough buyers, the order will continue to execute at the next available prices until it’s completely filled, potentially at a lower price .

Understanding these dynamics is crucial for effective risk management in trading. 

Do stop losses work in a crash?

Stop-loss orders can be quite tricky during a market crash. In theory, they’re designed to protect you by automatically selling your position if the price falls to a certain level. However, in a crash, the market can move so quickly that your stop-loss might not execute at your specified price due to slippage and gaps .

  • Slippage: When a stop-loss is triggered, it becomes a market order. In a fast-moving market, the execution price can be significantly worse than your stop-loss level because the order chases the best available price, which might be much lower than expected .
  • Gaps: If the market opens significantly lower than your stop-loss level, your order will execute at the opening price, not your stop-loss price. This can lead to larger-than-expected losses .

Despite these challenges, stop-loss orders are still a crucial part of risk management. They help ensure you exit losing trades before they become catastrophic, even if they don’t always execute perfectly in extreme conditions . It’s important to be aware of these limitations and consider them when designing your trading strategy.

Can we put stop-loss for long term?

Absolutely, you can use stop-loss orders for long-term positions, and it’s actually a smart move to protect your investments over time. For long-term holdings, a trailing stop-loss can be particularly effective. This type of stop-loss adjusts as the stock price moves in your favor, allowing you to lock in profits while still giving the stock room to grow .

  • Trailing Stop-Loss: This is set at a certain percentage below the highest price reached since you entered the trade. As the stock price increases, the trailing stop moves up, but it doesn’t move down. This way, if the stock price reverses and hits the trailing stop, you exit the position, securing your gains .
  • Volatility Considerations: For long-term positions, it’s often better to use a wider trailing stop, like 20-30%, to accommodate normal market fluctuations without getting stopped out prematurely .
  • Risk Management: Always align your stop-loss strategy with your overall risk management plan. This ensures you’re not risking more than you’re comfortable with, even in the long term .

Using stop-loss orders in this way helps you manage risk and protect your capital while still participating in potential long-term growth.

 

How do you calculate a stop-loss?

Calculating a stop-loss involves determining the price level at which you’ll exit a trade to limit your losses. Here are a few methods to calculate it:

  • Chart-Based Stop-Loss: Identify a recent support level or turning point on the chart and set your stop-loss just below that level. This method uses technical analysis to find logical points where the trade might be invalidated .
  • Volatility-Based Stop-Loss: Use the Average True Range (ATR) to determine how much the price typically moves. A common approach is to set your stop-loss a certain number of ATRs below the current price. For instance, you might use 2-3 ATRs for a tighter stop or 4-6 ATRs for a looser stop .
  • Percentage-Based Stop-Loss: Decide on a percentage of the stock price you’re willing to risk. For example, you might set a stop-loss at 5-10% below the entry price for a tighter stop, or 15-25% for a looser stop .

Each method has its pros and cons, and the best choice depends on your trading strategy and risk tolerance. Backtesting your strategy can help determine which stop-loss method works best for you . 

What is an example of a stop order?

A stop order is a type of order used to limit losses or protect profits on a position. Here’s a practical example:

Let’s say you bought a stock at $52 and you want to protect yourself from a significant loss. You decide to place a stop-loss order at $49. If the stock price falls to $49, your stop-loss order is triggered, converting into a market order. This means your stock will be sold at the best available price, which could be $49 or potentially lower, depending on market conditions and liquidity .

The main advantage of a stop order is that it helps you manage risk by automatically exiting a trade if the price moves against you. However, it’s important to be aware of slippage, which can occur if there aren’t enough buyers at your stop price, causing the execution price to be lower than expected .

This example illustrates how a stop order can be a powerful tool for risk management in trading.

What are common stop-loss mistakes?

When it comes to stop-loss orders, traders often make several common mistakes that can significantly impact their trading outcomes:

  • Tight Stop-Losses: Using stop-losses that are too tight can be problematic, especially in mean reversion trading. Tight stops can lead to small gains turning into losses because the trade might move against you before bouncing back. This is particularly true if you’re relying on a high win rate for positive expectancy .
  • Ignoring Volatility: Not accounting for market volatility can lead to stop-losses being triggered too easily. A volatility-based stop-loss, which uses the Average True Range (ATR), can help accommodate normal price fluctuations and prevent premature exits .
  • Hold and Hope: Failing to exit a trade when a stop-loss is triggered, hoping the market will turn around, can lead to massive losses. It’s crucial to stick to your plan and exit when your stop is hit to avoid large drawdowns .
  • Systematic Errors: Making systematic mistakes, like consistently setting stop-losses too close due to fear of loss, can erode your trading performance over time. These small errors add up and can have a significant impact on your account .
  • Not Backtesting: Failing to backtest your stop-loss strategy can lead to unexpected results. Testing different stop-loss methods helps determine what works best for your trading system and market conditions .

Avoiding these mistakes can dramatically improve your trading results.

What happens if the market opens below stop-loss?

If the market opens below your stop-loss level, your stop-loss order will be triggered, but it will execute at the best available price, which could be significantly lower than your stop-loss level. This situation is known as a gap down, and it can lead to larger-than-expected losses due to slippage .

Here’s how it typically plays out:

  • Gap Down: If the market opens significantly lower than your stop-loss level, your order will execute at the opening price, not your stop-loss price. This can result in a larger loss than anticipated .
  • Slippage: In a fast-moving market, the execution price can be worse than your stop-loss level because the order chases the best available price, which might be much lower than expected .

This is one of the risks associated with stop-loss orders, especially in volatile markets or during significant news events. It’s important to be aware of these limitations and consider them when designing your trading strategy.

Why does my stop-loss always hit?

If your stop-loss is consistently getting hit, it might be due to a few common issues:

  • Tight Stop-Losses: One of the most frequent mistakes is setting stop-losses too tight. This can lead to getting stopped out by normal market fluctuations or “noise,” rather than significant price movements. It’s crucial to give your trades enough room to breathe, especially in volatile markets .
  • Volatility Ignorance: Not accounting for the stock’s volatility can result in stop-losses being triggered too easily. Using a volatility-based stop-loss, like one calculated with the Average True Range (ATR), can help adjust for this by setting wider stops for more volatile stocks and narrower stops for less volatile ones .
  • Emotional Reactions: Sometimes, traders adjust their stop-losses based on emotions rather than a systematic approach. This can lead to inconsistent results and more frequent stop-outs .
  • Market Conditions: If the market is particularly choppy or trending against your position, it might naturally hit your stop-loss more often. It’s important to ensure your trading strategy aligns with current market conditions .

To improve your results, consider backtesting different stop-loss strategies to find what works best for your trading system.

What are the risks of using stop-loss?

Using stop-loss orders comes with several risks that traders should be aware of:

  • Slippage: When a stop-loss order is triggered, it becomes a market order, which means it will execute at the best available price. In fast-moving markets, this can lead to slippage, where the execution price is worse than the stop-loss level you set. This can erode your profitability significantly, especially in volatile or illiquid markets .
  • Intraday Noise: Stop-loss orders can be triggered by short-lived price spikes or intraday volatility, causing you to exit a trade prematurely. This is frustrating because the price might quickly recover after hitting your stop-loss, leaving you on the sidelines as the market moves in your favor .
  • Gap Risk: If the market gaps down overnight or over the weekend, your stop-loss might be executed at a much lower price than expected. This can result in larger losses than anticipated, as the order will execute at the opening price, which could be significantly below your stop-loss level .
  • Stop Hunting: There’s a perception that large market players might push prices to trigger stop-loss orders, known as stop hunting. While this is debated, it’s a risk to consider, especially if your stops are placed at obvious levels .

Despite these risks, stop-loss orders are crucial for managing risk and preventing large losses. It’s important to design your trading system to account for these risks and backtest different stop-loss strategies to find what works best for you .

Is stop-loss a pending order?

A stop-loss order is indeed a type of pending order. It’s not active in the market until a specific price level is reached. When you set a stop-loss, you’re essentially instructing your broker to execute a market order once the price hits your predetermined stop level. Until that point, the order remains pending and is held by your broker .

Here’s how it works:

  • Pending Status: The stop-loss order is not visible in the market order book until the stop price is triggered. This means it’s pending and waiting for the market to reach your specified level .
  • Activation: Once the stop price is hit, the stop-loss order converts into a market order and is executed at the best available price. This is where slippage can occur, as the execution price might differ from your stop level due to market conditions .

This pending nature of stop-loss orders is crucial for risk management, as it allows you to automatically exit a position if the market moves against you.

How much stop-loss is good?

Determining the right stop-loss level is crucial for managing risk effectively in trading. The appropriate stop-loss can vary depending on your trading strategy, market conditions, and risk tolerance. Here are some guidelines to consider:

  • Volatility-Based Stop-Loss: This approach uses the Average True Range (ATR) to set stop-loss levels. By placing your stop-loss a certain number of ATRs away from your entry price, you can account for the stock’s volatility. Typically, 2-3 ATRs are used for tighter stops, while 4-6 ATRs are for looser stops .
  • Percentage-Based Stop-Loss: This method involves setting a stop-loss at a fixed percentage below your entry price. Common percentages range from 5-10% for tighter stops to 15-25% for looser stops. However, this approach doesn’t adapt well to different volatility levels .
  • Chart-Based Stop-Loss: This involves setting your stop-loss just below a recent support level or turning point on the chart. While easy to calculate, it might not be as effective as volatility-based stops .

Ultimately, the best stop-loss level depends on your specific trading system and risk management strategy. It’s important to backtest different stop-loss methods to see which works best for your trading style.
