Trend Following Rules

Trend following is a style of trading that attempts to capitalize on prevailing trends in financial markets. It's a strategy built on the premise that trends, once established, are more likely to continue than to reverse. This article will provide a comprehensive guide to trend following rules, suitable for beginners, covering core concepts, key indicators, risk management, and practical examples. It assumes no prior trading knowledge, though a basic understanding of financial markets is helpful. This article will also link to other relevant Trading Strategies articles on this wiki.

What is Trend Following?

At its core, trend following is about identifying and participating in existing trends. Instead of trying to predict market tops or bottoms (a notoriously difficult task), trend followers aim to *react* to price movements. The underlying philosophy is that markets often exhibit momentum; prices that have been rising are likely to continue rising for a period, and prices that have been falling are likely to continue falling.

It's important to understand that trend following doesn’t mean blindly buying every rising price or selling every falling price. It involves a set of rules and criteria to identify legitimate trends and filter out temporary fluctuations, sometimes called "noise." This noise can lead to false signals and losing trades. Effective trend following requires discipline, patience, and a well-defined trading plan. More information on developing a Trading Plan can be found elsewhere on this wiki.

Identifying Trends

The first step in trend following is identifying whether a trend exists. Several methods can be used, ranging from simple visual inspection of price charts to more sophisticated technical analysis.

Visual Inspection: This is the most basic method. Look for a series of higher highs and higher lows to identify an uptrend, and a series of lower highs and lower lows to identify a downtrend. This method is subjective and prone to errors, especially on volatile markets.
Moving Averages: Moving Averages are one of the most popular tools for identifying trends. A moving average smooths out price data over a specified period, making it easier to see the underlying trend. Common periods include 50-day, 100-day, and 200-day moving averages.

   * *Uptrend:* Price consistently above the moving average.
   * *Downtrend:* Price consistently below the moving average.
   * *Crossovers:*  When a shorter-period moving average crosses above a longer-period moving average, it can signal the start of an uptrend (a "golden cross"). Conversely, when a shorter-period moving average crosses below a longer-period moving average, it can signal the start of a downtrend (a "death cross").  However, these signals can be lagging and produce false signals.

Trendlines: Trendlines are lines drawn on a chart connecting a series of highs (in a downtrend) or lows (in an uptrend). A break of a trendline can signal a potential trend reversal. See Trendline Analysis for more details.
Price Action: Analyzing the patterns formed by price movements on a chart. Concepts like higher highs and lows, support and resistance levels, and candlestick patterns can provide clues about the prevailing trend. Candlestick Patterns are a useful part of price action analysis.
ADX (Average Directional Index): ADX is a technical indicator used to measure the strength of a trend. Values above 25 generally indicate a strong trend, while values below 20 suggest a weak or sideways trend. Understanding ADX Indicator is crucial for confirming trend strength.

Trend Following Rules: Entry Signals

Once a trend has been identified, the next step is to determine when to enter a trade. Here are some common entry rules:

Moving Average Crossovers: As mentioned earlier, crossovers of moving averages can signal entry points. For example, a trader might buy when the 50-day moving average crosses above the 200-day moving average.
Breakout Strategy: Entering a trade when the price breaks above a resistance level (in an uptrend) or below a support level (in a downtrend). This requires identifying key Support and Resistance Levels. This often works best with volume confirmation – a breakout accompanied by increased trading volume is more likely to be genuine.
Pullback Strategy: Waiting for a temporary pullback (a short-term reversal) within a larger trend before entering a trade. This allows for a potentially better entry price. Identifying Fibonacci Retracements can assist in pinpointing likely pullback areas.
MACD (Moving Average Convergence Divergence) Crossovers: The MACD is a momentum indicator that can also be used to generate entry signals. A bullish crossover (MACD line crossing above the signal line) can signal a buy opportunity, while a bearish crossover can signal a sell opportunity. Learn more about the MACD Indicator.
RSI (Relative Strength Index) Overbought/Oversold: While primarily an oscillator, RSI can confirm trend strength. In an uptrend, waiting for the RSI to briefly enter oversold territory (below 30) before entering a long position can be effective. In a downtrend, waiting for the RSI to briefly enter overbought territory (above 70) before entering a short position can be effective. RSI Indicator details can be found on this wiki.

Trend Following Rules: Exit Signals

Just as important as entry signals are exit signals. These determine when to take profits or cut losses.

Trailing Stop Loss: This is the most common exit strategy for trend followers. A trailing stop loss is a stop-loss order that automatically adjusts as the price moves in your favor. For example, you might set a trailing stop loss at 10% below the highest price reached during an uptrend. As the price rises, the stop loss also rises, locking in profits. If the price reverses and falls to the stop loss level, the trade is automatically closed. This allows the trade to continue profiting as long as the trend persists.
Fixed Percentage Profit Target: Setting a predetermined profit target, such as 20% or 30%. Once the price reaches this target, the trade is closed. However, this can result in missing out on potential profits if the trend continues beyond the target.
Time-Based Exit: Closing a trade after a specific period, regardless of profit or loss. This is useful for limiting exposure to the market.
Moving Average Exit: Exiting a trade when the price crosses below a key moving average (in an uptrend) or above a key moving average (in a downtrend).
Volatility-Based Exit: Using indicators like Average True Range (ATR) to set exit levels based on market volatility. ATR Indicator is a useful tool for this purpose.

Risk Management in Trend Following

Trend following, like all trading strategies, involves risk. Effective risk management is crucial for protecting your capital.

Position Sizing: Determining the appropriate size of each trade based on your account balance and risk tolerance. A common rule is to risk no more than 1-2% of your account on any single trade. See Position Sizing for more detail.
Stop Loss Orders: Using stop loss orders to limit potential losses on each trade. As mentioned earlier, trailing stop losses are particularly effective for trend following.
Diversification: Trading a variety of markets and asset classes to reduce overall risk. Don’t put all your eggs in one basket.
Avoid Overtrading: Only take trades that meet your predefined criteria. Don’t chase trades or force opportunities.
Understand Drawdown: Trend following strategies can experience periods of drawdown (losses). It's important to be prepared for this and have a plan for managing drawdown. Learn about Drawdown Calculation and management.
Correlation Analysis: Understanding the correlation between different assets to avoid unintentional concentration of risk.

Trend Following Strategies: Examples

Here are a few examples of trend following strategies:

Simple Moving Average Crossover: Buy when the 50-day moving average crosses above the 200-day moving average. Sell when the 50-day moving average crosses below the 200-day moving average. Use a trailing stop loss set at 10% below the highest price reached.
Breakout with Volume Confirmation: Identify key resistance levels. Buy when the price breaks above the resistance level on strong volume. Use a trailing stop loss set at 5% below the breakout level.
Pullback to Moving Average: Identify a strong uptrend. Wait for the price to pullback to the 50-day moving average. Buy when the price bounces off the moving average. Use a trailing stop loss set at 3% below the low of the pullback.
ADX & MACD Combination: Only take long trades when ADX is above 25 and the MACD line crosses above the signal line. Use a trailing stop loss based on ATR.

Common Pitfalls of Trend Following

Whipsaws: False signals caused by temporary price fluctuations. These can lead to losing trades. Using filters (such as ADX or volume confirmation) can help reduce whipsaws.
Lagging Indicators: Many trend following indicators are lagging, meaning they react to past price movements rather than predicting future movements. This can result in late entries and smaller profits.
Overfitting: Optimizing a strategy to perform well on historical data but failing to perform well in live trading. This is a common problem in backtesting. Using robust backtesting methods and walk-forward analysis can help mitigate overfitting.
Emotional Trading: Letting emotions influence trading decisions. This can lead to impulsive trades and poor risk management. Stick to your trading plan and avoid making decisions based on fear or greed.
Ignoring Market Context: Failing to consider broader market conditions, such as economic news or geopolitical events. These factors can influence trends and invalidate trading signals.
