Key Points
Moving average trading strategies can help traders measure market momentum, analyze trends, and identify potential market reversals.
Moving average trading strategies include double moving average crossover, moving average bands, moving average envelopes, and exponentially smoothed moving average (MACD).
While moving average trading strategies can provide valuable insights into market behavior, the interpretation of their signals can be subjective. To reduce risk, traders often combine these strategies with methods such as fundamental analysis.
Introduction
Moving Average (MA) is a commonly used technical analysis indicator that smooths price data over a specified time period. They can be used in trading strategies to identify potential trend reversals, entry and exit points, support/resistance (S/R) levels, etc. This article will explore several moving average trading strategies and how each one works and the insights it can provide.
Why use a moving average trading strategy?
Moving averages can filter out market noise by smoothing price data, helping traders effectively identify market trends. Traders can also determine market momentum by observing the interaction between multiple moving averages. In addition, moving averages are very flexible, allowing traders to freely adjust their strategies based on different market conditions.
1. Double Moving Average Crossover
The dual moving average crossover strategy requires the use of two moving averages of different periods. Traders typically use a short-term moving average and a long-term moving average, such as a 50-day MA and a 200-day MA. Typically, these two moving averages are of the same type, such as simple moving averages (SMAs). However, traders can also use two different types of moving averages, such as an SMA and an exponential moving average (EMA).
In this trading strategy, traders need to pay attention to the crossover points between the two moving averages. When the short-term moving average crosses above the long-term moving average (also known as the golden cross), a bullish signal occurs, indicating a possible buying opportunity. Conversely, when the short-term moving average crosses below the long-term moving average (also known as the death cross), a bearish signal occurs, indicating a possible selling opportunity.
2. Moving Average Bands
Moving Average Bands are composed of multiple moving averages of different periods. A moving average band can be composed of 4 to 8 SMAs, but the specific number may vary depending on personal preference. Traders can also adjust the intervals between MAs to suit different trading environments. For example, by default, the moving average band consists of 4 SMAs, namely 20-day, 50-day, 100-day, and 200-day SMAs.
When using the moving average band trading strategy, traders need to track the expansion and contraction of the moving average bands. For example, if the moving average bands are expanding, that is, during the price increase, the short-term moving average is moving away from the long-term moving average, it indicates that the market trend is strengthening. Conversely, if the moving average bands are contracting, that is, the moving averages are converging or overlapping, it indicates that consolidation or a pullback is about to occur.
3. Moving Average Envelope
The Moving Average Envelopes trading strategy uses only one moving average with two boundary lines set at fixed percentages above and below the moving average to form the envelope. The middle moving average can be either an SMA or an EMA, depending on the sensitivity required by the trader. A common Moving Average Envelopes trading strategy uses a 20-day SMA with the two envelopes set at 2.5% or 5% from the SMA. The ratio is not fixed and can be adjusted based on market volatility to capture more price fluctuations.
This trading strategy can be used to identify overbought and oversold conditions. If the price crosses above the upper envelope, it indicates that the asset may be overbought and there may be a sell opportunity. Conversely, if the price falls below the lower envelope, it indicates that the asset may be oversold and there may be a buy opportunity.
Moving Average Envelopes vs Bollinger Bands (BB)
Bollinger Bands (BB) are similar to Moving Average Envelopes in that they typically use a 20-day SMA as a centerline with two boundaries above and below that centerline. Despite the similar approach, there are some differences between the two indicators.
Moving average envelopes consist of two lines set at fixed percentages above and below a central moving average. In contrast, Bollinger Bands use two lines that are set two standard deviations from the central moving average.
In general, both Bollinger Bands and Moving Average Envelopes can be used to identify potential overbought and oversold conditions, but the way they are identified looks slightly different. Moving Average Envelopes signal when the price crosses above the upper envelope or below the lower envelope. For Bollinger Bands, they can also signal overbought and oversold conditions when the price moves towards or away from the upper and lower bands. However, Bollinger Bands can also provide additional insights into market volatility when the upper and lower bands are contracting or expanding.
4. Moving Average Convergence Divergence (MACD)
MACD is a technical indicator that consists of two main lines: the MACD line and the signal line, which is the 9-day EMA of the MACD line. The trading strategy can be used to effectively analyze changes in market momentum and potential trend reversals, using the interaction of the two main lines and a histogram representing the difference between them.
Traders can use divergence between the MACD and price action to identify potential trend reversals. Divergences are classified as bullish and bearish. In a bullish divergence, price forms lower lows while the MACD forms higher lows, signaling a possible reversal to the upside. Conversely, in a bearish divergence, price forms higher highs while the MACD forms lower highs, signaling a possible reversal to the downside.
Additionally, traders can use MACD crossovers. If the MACD line crosses above the signal line, it indicates bullish momentum and a potential buy opportunity. Conversely, if the MACD line crosses below the signal line, it indicates bearish momentum and a potential sell opportunity.
Conclusion
Moving average trading strategies can help traders analyze market trends and momentum changes, among other things. However, relying solely on these strategies can be risky because their interpretation is subjective. To reduce potential risk, traders can combine these strategies with other market analysis methods.
