A trend following system is a relatively straight forward approach to system trading which can be readily developed and managed by people with a full time job or those who do not have the time or inclination to sit in front of the computer trading for more than 30-60 minutes a day (like me!!).
As discussed in the Trend Trading strategy page, this is a great way to profit from large moves without having to manage positions on an intraday basis. Realistically most people with a full time job are not able to focus on managing their trades every day, so a trend trading system which involves a small amount of maintenance once each day may be just what you need.
he following sections describe the trend following system approach to each of the system components illustrated in the picture below: setup, entry trigger, initial stop and exit rules.
Of course there is an infinite array of potential eod trading signals that you could use for any trading strategy, so here we describe conceptually what you should be trying to achieve. You are free to select trading signals that suit your beliefs and objectives and also fit with the style of trading system that you are trying to develop.
Setup:
The setup sets the conditions under which we will consider taking a trade. If the setup is not in place then all entry triggers are ignored. The setup ensures the environment is right for your trading system to have a high probability of working.
In a trend following system your setup will primarily be focused on identifying that a strong trend is in place and that the trend is sufficiently stable to consider participating. It may be that the instrument is trending, but if it is either too volatile or not strong enough there may not be sufficient profit potential in the trade to justify taking the risk.
At the most basic level, an instrument can be considered to be trending if it has moved by more than some minimum threshold within a certain timeframe. The simplest setup might be something like the price is above the 200 day moving average, however this tends to be a bit blunt and let in some instruments that are not really moving.
The best trading signals are simple… The 200 day moving average is one of the most powerful indicators in technical analysis
Trend following systems may also consider the external market state as part of the setup before taking a trade. For example, some trend following systems only take a trade in the direction of the broader market trend. If you had this rule in your trading system and the major stock market index was trending up then you might only take long trades and ignore short trades.
Entry Trigger/Buy Signal:
Once your setup is in place, the entry trigger is the rule that determines the exact timing for when you want to enter the trade. Your objective for an entry trigger is to identify a low risk entry point.
A low risk entry point is a point at which you believe the trend has a higher than normal chance of continuing and where our initial stop has a lower than normal chance of getting hit.
Everyone will have slightly different beliefs about what actually constitutes a low risk entry point. Here are some example beliefs that you may want to test:
A low risk entry point occurs when…
- …there is a pullback followed by a resumption in the trend
- …there is a narrow range day (or days) followed by a volatility breakout
- …there is a volatility breakout in the direction of the trend
- …the previous X day high is exceeded
- …insert your own belief here
Note that these are not necessarily factual statements! In fact, I may not even believe that some of the above are true – they are just food for thought to stimulate you.
Everything about trading system design is based on your beliefs
You need to determine your own beliefs and test them with the right backtesting software during your trading system development process
Initial Stop Loss:
The initial stop loss is an extremely important component in the design of a trend trading / trend following system.
A tight initial stop will give a high percentage of losing trades, but your winning trades will return many times your average risk (high R Multiples). A wide initial stop will give you more winning trades but your winners will be smaller multiples of the amount you risked on each trade.
Given we usually apply a trend following system to a wide range of instruments, and these instruments all have different volatilities and behavioural characteristics, we prefer to use initial stops which adjust for the volatility in each of the instruments rather than a fixed percentage stop.
For example, your initial stop might be somewhere between 1.5 and 5 average true ranges below your entry price depending on what performance profile you are trying to achieve. A value anywhere in this range will most likely work, but you will need to be aware of the psychological impact of using a stop as tight as 1.5 ATRs given this will likely give you in the order of 80% losing trades depending on how good your entry trigger is.
Like every component of your trend trading system, the initial stop is based on your beliefs about the way the markets move. Many beliefs may be relevant, but here are a couple of ideas to stimulate your thinking (note these are phrased assuming a long only system):
A trade is likely to be wrong and I should exit if…
- …the price drops by X ATR below my entry price
- …the price falls below the lowest price of the last X days
- …the price falls below yesterday’s low price
- …the price drops below a key support level
- …the price drops below the X day moving average
- …add your own beliefs here
Again, these are not statements of fact, they are example beliefs that are meant to stimulate your thinking. You need to determine your own beliefs and test them with the right backtesting software to determine if your beliefs are valid.
Exit Rule:
In trend following systems, the exit rule is based on some measure of whether the trend has ended. There are many ways to measure when you believe the trend has ended or the risk of remaining in the trend is no longer warranted.
This is where your preferred timeframe becomes extremely important. For example, if you are happy to trade the primary multi-year trend, you are likely to have a much looser exit rule than if you trade the 1-3 month trend.
Some common methods of identifying the end of the trend include using…
- …a trailing volatility stop (eg. if price falls 4 ATR from the highest high you exit)
- …a trailing percentage stop (eg, if price falls 25% from the highest high you exit)
- …the price crossing below some moving average (eg. if price crosses below the 100 day moving average you should exit)
- …add your beliefs and ideas here
There are many other exit rules you may consider, but if you are after a PURE trend trading / trend following system then this style of exit is what is required.
Money Management And Position Size Rules:
Money management and position size rules are used to determine everything else about how you manage the portfolio of trades generated by your trading system. This includes questions such as:
- How much you should risk on each trade
- How many signals you will take in a particular instrument
- How many trades you will have open at any one point
- How much total exposure and leverage you take on
- How much exposure to related instruments you will have as a maximum
- How much long vs short exposure you should have
- What total open trade risk you are willing to accept
Answering these questions is virtually impossible without understanding how a portfolio of multiple simultaneous trades behaves. This is because your risk profile changes every day – every time the price moves on any of your trades, every time you enter a new trade, move a trailing stop level or close an old position. This can only be understood by using a portfolio level backtesting and simulation package combined with historical data for your chosen instruments.
Portfolio level simulation of your trading system using good backtesting software is absolutely critical
Once you have designed your system setup, entry, initial stop and exit rules, there is a significant amount of work then required on the money management and position size rules to ensure your system meets your objectives.
The primary consideration here should be to ensuring you remain in the game – because after all:
You can’t win the trading game if you are not in the game
(Capital preservation is critical to success)
So you must ensure that you risk a sufficiently small percentage of your account on each trade because (particularly in a trend following system) you will have a high percentage of losing trades. If you risk too much on each trade a long losing streak could wipe you out.
I strongly suggest you start with a small level, in the order of 0.5% or less, of your total account at risk on any one trade. You should also limit your exposure to a level in which you will not get killed by your largest expected drawdown – maybe just take on no leverage and test the impact of leverage as you learn and grow as a trader.
Note that this still does not guarantee survival, nothing can – it is all just about controlling risk as much as possible and improving our chances.
Each of the other money management rules listed above can be tested thoroughly in a good portfolio level backtesting package as part of your trading system development process.
Trend Following System Conclusion:
Each of the five components of a trend following system should be developed based on your own beliefs about the markets and based on your own objectives. Everything about trading system development is a tradeoff and there are no absolute ‘right answers’.
In our discussion on trading system development we will explain how to pull together the setup, entry trigger, initial stop, exit and money management/position size rules in a way that help you meet your objectives.
All parts of a trading system are connected – it is insufficient to understand each rule, you must understand how the rules interact
If you do not yet have your trend trading software for portfolio level backtesting and the market data to test your system on your chosen markets then this is now an important step. You cannot effectively undertake trading system development without these tools.

Frequently Asked Questions about Trend Following System
What is a trend-following trading system?
A trend-following trading system is a strategy that aims to capitalize on the momentum of market trends. Here’s a breakdown of how it works:
- Identify Trends: The system uses technical indicators like moving averages to determine the direction of the market. For instance, if the closing price is above both the 50-day and 200-day moving averages, it indicates an upward trend .
- Entry and Exit Rules: You enter a trade when a trend is confirmed, often on a breakout, such as when today’s close is the highest in the last 200 days. You hold the position as long as the trend continues .
- Risk Management: A key component is the use of stop-loss orders to protect against significant losses. For example, you might exit a position if it falls 20% from its high, ensuring that losses are kept small .
- Emotional Discipline: Trend-following requires patience and the ability to stick to the system’s rules, even during periods of drawdown or when the system experiences more losing trades than winning ones. The winners, however, tend to be large enough to offset the frequent small losses .
- Simplicity and Consistency: The strategy is simple to execute and doesn’t require constant monitoring, making it suitable for traders who want to manage their portfolios alongside other commitments .
This approach has been proven effective over time, allowing traders to profit from significant market movements while managing risk .
How do you build a trend-following system?
Building a trend-following system involves several key steps to ensure it’s robust and effective. Here’s a concise guide to get you started:
- Define Your Rules: Establish clear, objective rules for when to enter and exit trades. For example, you might enter a trade when the closing price is above both the 50-day and 200-day moving averages, indicating an upward trend .
- Set Entry and Exit Points: Use technical indicators to identify trends. A common approach is to enter on a breakout, such as when today’s close is the highest in the last 200 days. Exit using a trailing stop, which might be set to exit if the price falls 20-25% from its high .
- Risk Management: Implement stop-loss orders to protect against significant losses. This helps manage your risk and ensures that no single trade can significantly impact your portfolio .
- Backtesting: Test your system on historical data to ensure it has a positive edge. This involves simulating trades to see how the system would have performed in the past, helping you build confidence in its effectiveness .
- Diversification: Don’t rely on a single system. Build a portfolio of different strategies to spread risk and increase the likelihood of consistent returns .
By following these steps, you can develop a trend-following system that helps you capitalize on market movements while managing risk effectively.
What are the most effective indicators for trend-following?
When it comes to trend-following, there are several indicators that traders often find effective. Here are some of the most commonly used ones:
- Moving Averages: These are fundamental in trend-following systems. They help smooth out price action and identify the direction of the trend. A crossover of a short-term moving average above a long-term moving average can signal an uptrend, while the opposite indicates a downtrend .
- MACD (Moving Average Convergence Divergence): This indicator measures both trend and momentum. A crossover of the MACD line above the signal line suggests a buy signal, while a crossover below indicates a sell signal. It’s particularly useful for catching short to medium-term trending moves .
- RSI (Relative Strength Index): While often used for identifying overbought and oversold conditions, the RSI can also help confirm trends. A stock with an RSI above 70 might suggest a strong uptrend, while below 30 could indicate a strong downtrend .
- ATR (Average True Range): This measures market volatility and can help set stop-loss levels. In a trend-following system, a higher ATR might suggest a wider stop to accommodate increased volatility .
These indicators, when used together, can provide a comprehensive view of market trends and help traders make informed decisions.
What is an example of a trend-following strategy in action?
A classic example of a trend-following strategy in action is the breakout system. Here’s how it typically works:
- Entry: You enter a trade when today’s close is the highest in the last 200 days. This indicates a strong upward trend, and you’re essentially buying into the momentum .
- Holding: Once you’re in the trade, you hold the position as long as the trend continues. This means not reacting to minor fluctuations but staying in as long as the overall trend is upward .
- Exit: You exit the trade using a trailing stop. For instance, you might set a stop-loss to exit if the price falls 20-25% from its high. This allows you to capture a significant portion of the trend’s movement while protecting against major reversals .
This strategy is simple yet effective because it capitalizes on large price movements while minimizing emotional decision-making. By sticking to predefined rules, you can avoid the pitfalls of trying to predict market tops and bottoms, which is a common challenge for many traders .
Does trend-following really work in modern markets?
Trend-following does indeed work in modern markets, and it’s a strategy I’ve personally used for over 18 years with substantial and consistent profits . The beauty of trend-following lies in its simplicity and its ability to capitalize on significant price movements, regardless of market conditions. It’s not about predicting market tops or bottoms but rather about riding the trend until it shows signs of reversing .
One of the reasons trend-following continues to be effective is because it removes human emotion from trading decisions, allowing traders to systematically capture price moves driven by changes in fundamentals, investor sentiment, and company management . This systematic approach is particularly advantageous over mutual funds, which must stay fully invested and can’t easily adapt to changing market trends .
Moreover, trend-following has proven its resilience across various market conditions, from the tech boom of the 1990s to the global financial crisis of 2008 and beyond . The strategy’s ability to adapt and thrive in different environments is a testament to its enduring effectiveness.
If you’re considering trend-following, it’s crucial to understand that while it can be highly profitable, it also requires emotional discipline and patience, as the hit rate might not be high, but the big winners can more than make up for the frequent small losses .
What are the risks and benefits of trend-following?
Trend-following has its share of risks and benefits, making it a unique strategy in the trading world. Let’s break it down:
Benefits:
- Simplicity: Trend-following systems are straightforward, often relying on simple rules like moving averages or breakout strategies. This simplicity makes them accessible to traders without needing complex analysis .
- Profit from Big Moves: The strategy is designed to capture significant price movements, allowing traders to profit from large trends over time. This can lead to substantial gains, even if the win rate is relatively low .
- Emotional Discipline: By following a systematic approach, traders can remove emotions from their decisions, reducing the impact of fear and greed on trading outcomes .
- Adaptability: Trend-following can work across various market conditions, from bull markets to bear markets, as it focuses on riding trends rather than predicting market directions .
Risks:
- Frequent Small Losses: Trend-following systems often experience many small losses, as trades are cut short when trends fail to develop. This can be emotionally challenging for traders who prefer high win rates .
- Drawdowns: During periods when markets are choppy or range-bound, trend-following systems can experience significant drawdowns, testing a trader’s patience and discipline .
- Late Entries and Exits: The nature of trend-following means that entries and exits can be delayed, potentially missing the start of a trend or giving back profits at the end .
Overall, trend-following is a powerful strategy for those who can handle its emotional and psychological demands.
What time frame is best for trend-following strategies?
The best timeframe for trend-following strategies can vary depending on your trading goals and personal preferences. Here’s a breakdown of different timeframes and their benefits:
- Daily Charts: These are often favored for trend-following because they provide a good balance between signal and noise. Daily charts allow you to capture significant trends with manageable giveback at the end of a move. They also offer a long history of data for backtesting, which can enhance confidence in your system’s robustness .
- Weekly Charts: Trading on weekly charts can be less stressful and low maintenance, requiring only about 20 minutes a week to manage. This timeframe captures larger macro trends and is ideal for those who prefer a more hands-off approach. It provides high returns for effort and is suitable for busy individuals .
- Intraday Charts: While these can offer opportunities for trend-following, they tend to be noisier, with more false breakouts and shorter system lifespans. Intraday trading requires more frequent monitoring and can be more challenging to maintain a robust edge over time .
Ultimately, the best timeframe depends on your lifestyle, risk tolerance, and trading objectives. Diversifying across multiple timeframes can also help smooth your equity curve and reduce risk .
How does the Turtle Trading system relate to trend-following?
The Turtle Trading system is a classic example of a trend-following strategy. It was developed by Richard Dennis and William Eckhardt in the 1980s to prove that anyone could be taught to trade successfully with the right rules and discipline. Here’s how it relates to trend-following:
- Mechanical Approach: The system is entirely mechanical, meaning it relies on predefined rules rather than subjective judgment. This aligns perfectly with the principles of trend-following, which emphasize removing emotion from trading decisions .
- Trend Identification: The Turtle Trading system uses breakouts to identify trends. Traders enter positions when the price breaks above or below a certain level, signaling the start of a new trend. This is a fundamental aspect of trend-following, where the goal is to ride trends as they develop .
- Risk Management: The system incorporates strict risk management rules, including position sizing and stop-loss levels, to protect against large losses. This is crucial in trend-following, where small losses are common, but the aim is to capture large trends that more than compensate for these losses .
- Long-Term Perspective: Like many trend-following strategies, the Turtle Trading system is designed to capture long-term trends. It requires patience and discipline to hold positions through market fluctuations, waiting for the trend to play out .
Overall, the Turtle Trading system exemplifies the core principles of trend-following: systematic rules, trend identification, risk management, and a long-term perspective.
What is the win rate of trend-following systems?
Trend-following systems typically have a win rate ranging from 30% to 50% . This might seem low compared to other strategies, but the key to their success lies in the size of the winning trades relative to the losing ones. In trend-following, the winners are often significantly larger than the losers, which allows the strategy to be profitable even with a lower win rate .
The focus is on capturing large trends and letting them run, while keeping losses small when the trend doesn’t materialize. This approach can be emotionally challenging, as it involves accepting frequent small losses, but the occasional big wins can more than make up for them .
If you’re exploring trend-following, it’s crucial to maintain discipline and stick to your rules, as the strategy’s success depends on consistently capturing those big trends .

Excellent article that sums trend trading up very neatly! Love it!
Just one point, you could skip the initial stop. Only if you are willing to accept the volatility, though. Perhaps you can e.g. if you have a large number of stocks in your portfolio. You still need an exit rule. This rule will then double as you initial stop. This makes the system simpler which is the good thing about it. You need to backtest this of course to see if it is acceptable or not. An example is to use the lower Bollinger band as the exit point. If your entry follows a consolidation period with lower volatility, the lower band is reasonably close to your entry.
