The crossover itself is just the moment when the MACD crosses over the signal line, and depending on which direction it crosses, the indication taken by traders is different. The MACD indicator, or Moving Average Convergence Divergence indicator, is one of the most widely used technical indicators in trading. This indicator was first developed by Gerald Appel in the late 1970s and has become a staple tool for many traders in the stock market and other financial markets. You can see in the screenshot below how the price was moving higher very slowly over a long period of time.
We would naturally expect the MACD line to rise and fall in accord to the convergence and divergence of these two moving averages. You must pay attention to the relationship of the red and the green line. Notice in mid-December to mid-January where the shorter term moving average is pulling away from the longer term moving average. Then from the middle of January to mid-February the shorter term trend drops in comparison to the longer term trend. The indicators act as a tool which the traders can use to confirm their trading decisions, and it is worthwhile to check what the indicators are conveying before placing a buy or a sell order.
Verifying the MACD indicator
Introduced by John Bollinger in the 1980s, Bollinger Bands is perhaps one of the most useful technical analysis indicators. BB is used to determine overbought and oversold levels, where a trader will try to sell when the price reaches the top of the band and will execute a buy when the price reaches the bottom of the band. A trader can follow a simple 2 line crossover strategy with these two lines as discussed in the moving averages chapter and no longer wait for the centerline cross over. The difference between the two moving averages is called the MACD spread. The spread decreases when the momentum mellows down and increases when the momentum increases. To visualize convergence and the divergence traders usually plot the MACD value chart, often referred to as the MACD line.
In the following chart, you can see how the two EMAs applied to the price chart correspond to the MACD crossing above or below its baseline in the indicator below the price chart.

- Then, suddenly, price broke below the two moving averages with stronger which happened while the MACD lines crossed below 0 and also separated further.
- The moving average convergence divergence index was invented by Gerald Appel in the 1970s.
- The first number represents the number of time periods used to calculate the faster average.
- For example, the higher the underlying price such as Bank Nifty, naturally, the higher will be the magnitude of the MACD.
- Because there are two moving averages with various speeds, the quicker one will obviously be faster to react to price movement than the one that is slower.
Even though the move may continue, momentum is likely to slow and this will usually produce a signal line crossover at the extremities. Volatility in the underlying security can also increase the number of crossovers. The divergence at#5 is a signal we will explore below and it predicted the reversal. During the downtrend #6, the price then again stayed below the moving averages while the MACD lines stay below 0. At point #1, the price also formed a narrow range and when the price breaks out, the two indicator lines pull away from the 0 line and also separate each other. Then, during a trend, the moving averages can act as support and resistance and stay you in trends as the phase #2 and #4 show – the price never broke the moving averages.
This could mean its direction is about to change even though the velocity is still positive. This would be the equivalent to a signal line crossover but with the MACD line still being positive. Some traders might turn bearish on the trend at this juncture. Although the MACD is a very popular tool, it is just one trend following device. The strongest is divergence from price, then crossovers with the signal line, and lastly crossing over the 0 reference line. The formula is quite simple based on exponential moving averages .
A bullish divergence appears when MACD forms two rising lows that correspond with two falling lows on the price. This is a valid bullish signal when the long-term trend is still positive. The Moving Average Convergence Divergence zero line, also known as “centerline” divides the positive area of the chart from the negative. The MACD line oscillates above and below it, which is how you predict bullish and bearish momentum. The indicator is positive when it is above the zero line, and negative when it is below it.
When you see the two MACD indicator lines move away from each other, it means that momentum is increasing and the trend is getting stronger. When the two lines are coming closer to each other, it shows that price is losing strength. The MACD and average series are customarily displayed as continuous lines in a plot whose horizontal axis is time, whereas the divergence is shown as a bar chart inventory control models . As you can see in the chart below, a cross through the zero line is a very simple method that can be used to identify the direction of the trend and the key points when momentum is building. Useful as a stand-alone tool or in tandem with other technical indicators. Take notice of the price breaking out of a prior trend, even if divergence wasn’t present at the time of the reversal.
Moving averages are often used to determine and track trends. For instance, the 350, 200, 50, and 10 day moving averages are interpreted and traded differently. The variety of moving averages and how to read them will be discussed in a later article. A MACD sell signal occurs when the MACD line crosses below the signal line.
The MACD line oscillates above and below the zero line, which is also known as the centerline. These crossovers signal that the 12-day EMA has crossed the 26-day EMA. The direction, of course, depends on the direction of the moving average cross. Positive MACD indicates that the 12-day EMA is above the 26-day EMA. Positive values increase as the shorter EMA diverges further from the longer EMA.
MACD Pros and Cons ⚖️
MACD, short for moving average convergence/divergence, is a trading indicator used in technical analysis of securities prices, created by Gerald Appel in the late 1970s. It is designed to reveal changes in the strength, direction, momentum, and duration of a trend in a stock’s price. The moving average convergence divergence index was invented by Gerald Appel in the 1970s. Appel designed the MACD as a technical analysis tool to gain insight on stock prices, with the intent to reveal data about the stock’s momentum, strength, as well as directional assumptions. This article will focus the most popular indicator used in technical analysis, the moving average convergence divergence . The Moving Average Convergence Divergence or MACD as it is commonly referred to is an oscillator which highlights the strength of the trend and likely reversal thereof.
Because it is based on moving averages, this is considered a lagging indicator, although it does have elements of leading ones also. The next chart shows the S&P 500 ETF with four bearish divergences from August to November 2009. Despite less upside momentum, the ETF continued higher because https://1investing.in/ the uptrend was strong. Notice how SPY continued its series of higher highs and higher lows. Remember, upside momentum is stronger than downside momentum as long as the MACD is positive. The MACD may have been less positive as the advance extended, but it was still largely positive.
The Indicator
While 12, 26, and 9 are the typical value settings used with the MACD, traders can opt for other values depending on their trading style and goals. Traders may interpret the MACD indicator in various ways, but the more common techniques are crossovers, divergences, and rapid rises/falls. Looking at the E-mini S&P 500 future, from High #1 to High #2, the futures contract made higher highs, which is usually viewed as bullish. This chart of the E-mini S&P 500 Index Future shows bearish and bullish divergences. Another potential buy and sell signal is shown in the graph above in the Nasdaq 100 exchange-traded fund QQQQ chart. Crossovers are more reliable when they conform to the prevailing trend.
The MACD chills out a stock chart and lets you see what is happening in the bigger picture. It’s a great way to see whether you should enter a long or short position, and whether a trend is slowing down or ramping up, indicating when you might want to buy or sell. Conversely, the MACD can form two falling highs corresponding with two rising highs of the price.
Either indicator may signal an upcoming trend change by showing divergence from price . So, a signal line crossover takes place when the MACD line crosses above or below the signal line. The strength of the move determines how long the crossover will last. A bullish signal line crossover can be observed when the MACD line crosses above the signal line. On the contrary, a bearish crossover occurs when the MACD line crosses below the signal line.
When To Use And How To Read The MACD Indicator
When the bars turn from pointing up to pointing down , this is the same as the bearish crossover. On the other hand, if you notice the MACD is going up despite prices still dropping, this could signal a potential trend change from bear to bull. The idea is that the shorter term trend is signaling a change when compared to a longer trend.
One of the main problems with a moving average divergence is that it can often signal a possible reversal, but then no actual reversal happens—it produces a false positive. The other problem is that divergence doesn’t forecast all reversals. In other words, it predicts too many reversals that don’t occur and not enough real price reversals. The MACD lines, however, do not have concrete overbought/oversold levels like the RSI and other oscillator studies.
Analysts will also vary the parameters of the MACD to track trends of varying duration. As the D in MACD, “divergence” refers to the two underlying moving averages drifting apart, while “convergence” refers to the two underlying moving averages coming towards each other. A fast EMA responds more quickly than a slow EMA to recent changes in a stock’s price. By comparing EMAs of different periods, the MACD series can indicate changes in the trend of a stock. It is claimed that the divergence series can reveal subtle shifts in the stock’s trend.
Day trading is subject to significant risks and is not suitable for all investors. Any active trading strategy will result in higher trading costs than a strategy that involves fewer transactions. Oversold Market – MACD line gains significant bearish distance from the Signal Line. Overbought Stock – MACD line gains significant bullish distance from the Signal Line. Bearish Divergence – Price increases, but MACD lines give lower tops and bottoms. Bearish divergences signalize for potentially strong bearish movement.

As you see the MACD trading tool consists of couple of lines and a histogram. Many stock traders confuse the two lines with ordinary Moving Averages, which smooth the general price action. Yes, the two lines are Moving Averages but not of the price action. The slower MACD refers to the moving average calculated over more time periods.
All investing involves risk, including loss of principal invested. Past performance of a security or strategy does not guarantee future results or success. Since you are now familiar with the MACD structure and its signals, we will now demonstrate a couple of trading cases including this indicator. The image above displays a classical overbought signal coming from the MACD indicator. After the price increase and the overbought signal, we observe a consistent price drop.
