What Is the MACD Indicator, and How Does It Work?
Reading Time: 5 minutesIt’s one of the most commonly used indicators in trading, but how does MACD actually work?
Traders utilize various technical indicators to make informed decisions regarding price direction and market activity. These indicators are designed for different purposes, with the Moving Average Convergence Divergence (MACD) indicator being among the most commonly employed tools for determining price direction and momentum.
Let’s look at how the MACD indicator works and how you can use it to determine trend direction and strength.
What Is the MACD Indicator?
MACD is a widely used technical analysis tool that crypto traders rely on to spot trend changes and potential buying or selling signals in the crypto market. It was developed by Gerald Appel in the late 1970s and has since found application in financial markets such as crypto, forex, and stock markets.
What Does MACD Indicate?
By applying the MACD indicator, crypto traders can identify a range of crucial market trends, such as divergences, crossovers, and overbought and oversold positions, which are key indicators in market analysis. We will examine how these are done shortly.
How Does the Moving Average Convergence Divergence Work?
The Moving Average Convergence Divergence (MACD) indicator gauges the correlation between two moving averages and can be represented as a histogram, which highlights price strengths and weaknesses. To comprehend how this indicator operates, it is essential to understand its fundamental features.
The MACD Line
The MACD line, denoted by a blue line, is derived by subtracting the longer exponential moving average (EMA) from the shorter exponential moving average. The EMA is a moving average that places significance on the most recent price data, making it responsive to recent price changes and a handy tool for identifying trends and buying and selling signals. EMA periods refer to the number of price points included in a specific measurement and depending on the indicator, you’ll use different EMA periods to find different trends.
The calculation involves subtracting the 26-period EMA from the 12-period EMA, and the difference is plotted on the chart along with a signal line.
The Signal Line
The signal line, on the other hand, is the 9-period EMA of the MACD line. As both the MACD and signal lines move above and below each other, it forms bullish and bearish signals. We will explain this in more detail later in this article.
MACD Histogram
The MACD histogram shows the difference between the MACD line and the signal line, representing it as bars. When the bars are above the zero line, the MACD line is above the signal line. Conversely, when the bars are below the zero line, the MACD line is below the signal line. This histogram also aids crypto traders in identifying potential trends and trend reversals.
The Zero Line
The zero line is a straight line in the MACD indicator that separates the positive and negative parts of the chart. The MACD line moves above and below the zero line to show if the market is bullish or bearish. If the histogram is above the zero line, it means the market is going up, and if it is below the zero line, it means the market is going down.
How to Use MACD in Crypto Trading
So, how do you interpret the signals derived from the MACD indicator? There are several effective approaches to determining the prevailing market trend and identifying potential market reversal points.
1. MACD Bullish Trend
When the MACD line is above the signal line, the trend is considered bullish, and the further it is from the zero line, the stronger the trend is. Traders can also determine market trends by examining the histogram. The trend is bullish when the histogram is above the zero line or green. Longer histogram bars indicate a stronger trend, while shorter bars indicate a weaker trend.
2. MACD Bearish Trend
In contrast, the MACD line stays below the signal line in a bearish trend, and the further apart they are, the stronger the trend becomes. When the histograms are below the zero line, the trend is bearish. The length of the histogram bars can also determine the strength of the trend.
3. MACD Crossover
A trend reversal indicates a shift in an ongoing trend, as suggested by its name. It marks the point at which a previously bullish trend transitions to bearish or vice versa.
One common method for identifying a trend reversal is observing the crossover of the MACD and signal lines. When the MACD line crosses above the signal line in a bearish trend, it indicates a shift to a bullish trend. Conversely, the MACD line crossing below the signal line indicates a bearish reversal, suggesting that the trend may continue to move downward.
4. Overbought and Oversold Conditions
The MACD indicator can be utilized to identify overbought and oversold conditions. An overbought condition occurs when the MACD line is substantially higher than the signal line. At the same time, an oversold condition happens when the MACD line is significantly lower than the signal line. Traders can make use of these signals to enter or exit positions based on their preferred trading strategy.
5. Price Divergence
A divergence between the price and the MACD indicator can signal a potential trend reversal. This occurs when the price reaches new highs or lows, but the MACD does not follow. For example, in a bullish divergence, the price continues downward and forms a new low while the corresponding MACD indicates otherwise.
Conversely, the bearish divergence signals a weakening price movement. Therefore, a possible reversal is imminent when a divergence occurs.
Limitations of the MACD Indicator
Although the MACD indicator is a good tool for technical analysis, it is crucial to remember that it is not foolproof. It produces false signals that mislead traders into believing that a trend reversal is imminent, only for the ongoing trend to continue.
Moreover, price divergence, which MACD attempts to identify, may not always accurately predict a trend reversal, as price may continue in the ongoing direction. Consequently, traders must seek additional indicators or confirmations to validate potential moves.
Using MACD With Other Technical Indicators
Since MACD can give false signals and its results can be influenced by market volatility, traders should always use MACD in conjunction with technical indicators of various categories and fundamental analysis to make well-informed trading decisions.
As with many other technical indicators, MACD is subjective and can be customized to suit individual preferences. Traders often adjust parameters, such as a MACD histogram and the number of periods used in the calculations, to align with their specific trading styles. The possible combinations of these parameters are limitless and may lead to divergent results, unique to each trader. This raises the need to study and test various configurations to determine the optimal settings for your strategy to achieve the best results.
Take Time to Practice
The Moving Average Convergence Divergence (MACD) indicator is a viable indicator that can provide traders with valuable insights into market trends, but it requires practice and experience to master. Moreso, its effectiveness depends on how well it is interpreted, and this varies depending on the types of traders that use it.
As a trader, it is important to take the time to practice using the MACD indicator and understand how it works in different market scenarios. This can involve analyzing and backtesting with historical data, testing different strategies, and experimenting with different settings. Using the MACD indicator without practice and study can lead to continuous losses.
