The moving average convergence divergence (MACD) is an oscillator that combines two exponential moving averages (EMA)—the period and the period—to indicate the momentum of a bullish or bearish trend. MACD can be used to signal opportunities to enter and exit positions.
It is one of the most popular technical indicators in trading and is appreciated by traders worldwide for its simplicity and flexibility.
Read on to learn about the MACD and some of the MACD strategies used by traders.
The concept behind the MACD is straightforward. It calculates the difference between a security's day and day exponential moving averages (EMA). Each moving average uses the closing price of its period ( and day) to calculate its moving average value.
On the MACD chart, a nine-period EMA of the MACD itself is also plotted. This line is called the signal line. It acts as a trigger for buy and sell decisions when the MACD crosses over it. The MACD is considered the faster line because the points plotted move more than the signal line, which is regarded as the slower line.
The MACD histogram is a visual representation of the difference between the MACD and its nine-day EMA—not highs and lows. The histogram is positive when the MACD is above its nine-day EMA and negative when the MACD is below its nine-day EMA. The point on the histogram where momentum is zero is the zero line.
If prices change rapidly, the histogram bars grow longer as the speed of the price movement—its momentum—accelerates and shrinks as price movement decelerates.
Divergence refers to a situation where factors move away from or are independent of others. With the MACD, it is a situation where price action and momentum are not acting together.
For instance, divergence can indicate a period where the price makes successively lower highs, but the MACD histogram shows a succession of higher lows. In this case, the highs are moving lower, and price momentum is slowing, foreshadowing a decline that eventually follows.
By averaging up their short, the trader eventually earns a handsome profit, as the price makes a sustained reversal after the final point of divergence.
The moving average convergence divergence was invented by Gerald Appel.
The MACD histogram can be a useful tool for some traders. While we've explained a little bit above about how to read it, here's how it works. It plots out the difference between the fast MACD line and the signal line. Traders can use the MACD histogram as a momentum indicator to jump ahead of changes in market sentiment.
There are three different elements involved with the histogram, which is mapped out around a baseline:
Keep in mind, though, that the MACD histogram has its faults (see the "Drawbacks" section below). Many traders often use other tools and techniques to determine and make their moves based on market sentiment, such as the trading volume of a given security.
A crossover occurs when the signal and MACD line cross each other. The MACD generates a bullish signal when it moves above its own nine-day EMA and triggers a sell signal (bearish) when it moves below its nine-day EMA.
When the MACD crosses from below to above the zero line, it is considered a bullish signal. Traders generally take long positions when this occurs. If it crosses from above to below the zero line, it is considered a bearish signal by traders. Traders then enter short positions to take advantage of falling prices and increasing downward momentum.
In both cases, the longer the histogram bars, the stronger the signal. When there is a strong signal, it is more likely—but not guaranteed—that the price will continue in the trending direction.
The money flow index allows traders to use price and trading volume to identify and determine when assets are overbought or oversold in the market. This oscillator moves between 0 and where readings below 20 are oversold and 80 are considered overbought.
One of the drawbacks of this strategy, though, is that it tends to produce fewer signals. That's because the readings it produces are extreme due to the fact that they are focused on spurts in volume and prices.
The relative vigor index (RVI) is a commonly used momentum indicator in technical analysis. It measures how strong a trend is by comparing the trading range of a certain security with its closing price. The comparison is made by using a simple moving average (SMA) to smooth the results out.
Traders generally believe that the value of the RVI increases as a bullish trend continues to gain momentum. That's because, in this case, an asset's closing price tends to fall at the higher end of the range. The opening price, on the other hand, stays further down on the lower end of the range.
Traders may often use the MACD and relative strength index (RSI) indicator strategy. This allows them to use both the RSI and the SMA to their advantage. But what are they?
Combining these three strategies together allows traders to:
Like any oscillator or indicator, the MACD has drawbacks and risks.
We'll use our zero-cross image for a MACD trading example. As trading proceeds, you observe the MACD initially crossed the zero line from below, then crossed again from above. A trader might notice the histogram bars moving down with the MACD, indicating a possible reversal and opportunity for a short trade.
When the line crossed from above, the trader could take a short position and net a profit when the prices began to climb again.
The zero-cross strategy could be used again to take a long position when the MACD crosses the zero line from below. At the point circled in our image, prices have been rising and momentum is up. The trader could take a long position at this point.
There are several strategies for trading the MACD. The best strategy for you depends on your preferred trading style and which one you're comfortable using.
In general, most traders use candlestick charts and support and resistance levels with MACD.
MACD uses 12 and 26 as the default number of days because these are the standard variables most traders use. However, you can use any combination of days to calculate the MACD that works for you.
MACD is one of the most-used oscillators because it has been proven to be a reliable method for identifying trend reversals and momentum. There are various strategies for trading MACD, including those described above. Try each out to find the one that works best for you and your trading plan.
