Trend following and session breaks
Moving averages (MAs) are among the most popular tools in technical analysis thanks to their simplicity and effectiveness in identifying trends. By smoothing out price data, they help traders cut through market noise and focus on the bigger picture.
In this article, we’ll cover what moving averages are, the different types, how they work across timeframes, and practical strategies for using them in both bullish and bearish trend-following trades.
What is a Moving Average?
A moving average is a statistical calculation that takes the average of an asset’s prices over a specific period of time. By doing so, it smooths out short-term fluctuations and highlights the underlying trend.
For example, a 50-day moving average tracks the average closing price over the past 50 trading days, updating with each new day’s price. This allows traders to see whether an asset is generally trending upward, downward, or sideways.
Types of Moving Averages
Different moving averages serve different purposes, depending on how much emphasis they place on recent price movements.
Simple Moving Average (SMA):
The SMA gives equal weight to all data points. It is less sensitive to recent changes, making it more stable but slower to react.Exponential Moving Average (EMA):
The EMA assigns greater weight to the most recent prices, allowing it to react more quickly to market changes. It’s useful in fast-moving markets but can also generate false signals during choppy price action.Weighted Moving Average (WMA):
The WMA also emphasizes recent prices, but in a linear fashion. Each previous price gets progressively less weight as you move back in time.
Example: On the EUR/USD daily chart, a 20-period EMA reacts faster to price reversals than a 20-period SMA, which lags slightly but provides a smoother curve.
Common Moving Average Periods
Moving averages can be applied to different time horizons depending on trading style:
Short-term trend: 10–20 days (about 2–4 weeks of trading)
Medium-term trend: 50 days (roughly two months of trading)
Long-term trend: 200 days (close to one full trading year)
For example, if a stock trades above its 200-day SMA, it’s typically considered to be in a long-term uptrend.
Why Use Moving Averages in Trading?
Moving averages serve three main purposes:
Trend Identification:
Quickly determine whether an asset is trending upward, downward, or sideways.Support & Resistance Levels:
MAs often act as dynamic support or resistance. For instance, in an uptrend, prices may pull back toward the 50-day MA before bouncing higher.Signal Generation:
Moving averages are commonly used in crossover strategies:Golden Cross (Bullish): The 50-day MA crosses above the 200-day MA.
Death Cross (Bearish): The 50-day MA crosses below the 200-day MA.
Bullish Trend-Following Strategy
Let’s look at an example using the USD/JPY daily chart:
From point A to B, price moved above both the 20-day and 50-day SMAs, confirming a short- and medium-term uptrend.
At point B, price was far above the moving averages. Entering here would be unattractive due to poor risk-to-reward.
Smart traders wait for pullbacks toward the moving averages.
At point C, price tested the 50-day SMA around 151.80 but didn’t confirm momentum.
At point D, price tested the same support and formed a bullish Hammer candlestick — a strong confirmation to enter long above the Hammer’s high.
Pro tip: This same method works on shorter timeframes like 4-hour or 1-hour charts.
Bearish Trend-Following Strategy
Now consider the USD/CHF daily chart:
From point A to B, price stayed below the 20-day and 50-day SMAs, confirming a downtrend.
At point B, price had already fallen far below the averages, making it unattractive to enter short.
Traders waited for a retrace toward the moving averages acting as resistance.
At point C, price touched the 20-day SMA near 0.8730 but showed no bearish confirmation.
At point D, price tested the same resistance and formed a Bearish Marubozu candlestick — a strong sell signal with entry below its low.
Again, this strategy is effective on both daily and intraday charts.
Advantages of Moving Averages
✅ Simple to use: Easy to understand for both beginners and professionals.
✅ Clear trend signals: Help smooth out noise for better decision-making.
✅ Customizable: Can be adjusted for day trading, swing trading, or long-term investing.
Disadvantages of Moving Averages
❌ Lagging indicator: Since they use past prices, MAs often provide delayed signals, especially in fast-moving markets.
❌ False signals in sideways markets: When prices consolidate, moving averages may produce misleading signals like whipsaws.
Final Thoughts
Moving averages are one of the most versatile and widely used tools in technical analysis. They help traders identify trends, act as dynamic support and resistance, and generate entry and exit signals.
For best results:
Use shorter MAs (e.g., 10–20) for quicker signals, but pair them with longer MAs (50–200) for context.
Combine MA strategies with candlestick patterns or support/resistance zones for stronger confirmations.
Avoid relying on them in sideways or low-volume markets.
Whether you’re trend-following in forex, stocks, or crypto, moving averages can provide the foundation of a robust trading strategy.
