Looking for how to read the MACD study? This study will be added to our divergence series. We will discuss the how to read MACD and how it should be used. What is the MACD? It’s a “moving average” study that presents “convergence and divergence” signals between the Value Line and the Avg Line. As a result, it’s also known as the Moving Average Convergence Divergence. For other divergence studies, you can check out the RSI Divergence Indicator Study and the OnBalanceVolume Indicator Study.

Here's How to Read the MACD Indicator
- Value = MACD Line
- Avg = Moving average of the MACD Line
- Diff = Difference between the Value and the Avg
- Value Line is value we get when we subtract the 26EMA from the 12EMA
In the picture below we open the user dialog box for the MACD Study inside ToS and see the signals settings. Let’s take a closer look.
From left to right, we have Value, Avg, and Diff. ZeroLine, UpSignal and DownSignal are also present but we can set them aside for now. To better understand how to read MACD, we need to understand what these things are inside this user dialog box.
Value, Avg, & Diff make up the critical pieces of the MACD Indicator Study.
Now that we have identified what the names represent, we can begin to decipher how to read MACD and what the moving average convergence divergence signals are made of. As a result, the picture below a candle stick chart shows the 26EMA and 12EMA.
The Value Line in the MACD study is nothing more than the value we get when we subtract the 26EMA from the 12EMA.
The Calculations for the MACD
The Value Line by it-self does not offer many useful signals. However, one signal it does offer alone is slope or market trend direction. When the Value line is pointed up then the price is in an uptrend. Likewise, if the value line is pointing down then price is in a downtrend.
The steeper the slope on the value line, the stronger the momentum of the trend. Remember that the Value Line is derived from two moving averages.
Just like moving averages, the Value Line Slope can offer some important clues. A sideways Value line is an indication of market uncertainty, consolidation, or “ranging patterns.” Use this as a guide on how to read MACD.
The Avg Line is the Value Line Average. Think on this for a moment. We took the 26EMA value and subtracted the 12EMA value to get the MACD Line.
Now we have the Avg Line which is the average of the MACD Line. Understanding why this is beneficial will help you understand why the MACD study is such a powerful tool; and why you need to know how to read MACD, especially when trading low float stocks.
Averages provide access to the mean. Since NO ONE can predict the market, the best we can do is try to understand what has already happened and try to develop an understanding of what COULD happen next based off the previous data.
An Average of ANYTHING is a great way to visualize where the COMMON ACTION is. To visualize where the “NORMAL” can be found. Once we can identify “normal” we can begin looking for signals that are not normal.
Value Line, Avg Line, & Diff Histogram
The Diff is presented in the MACD study as a Histogram. The Diff is the measured distance between the Value Line and the Avg Line.
In the picture above, you can see that when the Value Line converges with the Avg line, the Diff Swabs become shorter. When the Value Line and the Avg Line cross over the Diff Swabs also cross over from one side of the Zero Line to the other side of the Zero Line.
This is because the Diff Line is measuring the distance between the Value Line and the Avg Line. When they are touching (during the cross-over) there is no distance between them to measure.
Value, Avg, & Diff make up the critical pieces of the MACD Indicator Study.
How to Read MACD Default Settings
- When learning how to read MACD, the Avg Line has a default setting of 9EMA. If you look back at the picture of the user dialog box, you’ll see a Fast Length, a Slow Length, and a MACD length. We have already shown that the Fast Length default is 12 and the Slow Length default is 26. Now we understand the MACD Length is the length used to measure the Avg Line.
In a normal MACD study, the Avg Line is set with a default of 9. It is the average of the average convergence or divergence. Perhaps it is time to understand those terms more to better understand how to read MACD.
Example of Bullish Divergence
The MACD line is the measurement between two moving averages, as presented above. When those two moving averages move towards each other, they converge.
We’ve learned from the Moving Average Blog that when moving averages move towards each other, it is a signal of failing momentum. By measuring this movement towards each other we can develop some analysis on the strength of the trend presented by the sloped Value Line. As a result, we can better understand how to read MACD.
An example of Bearish Divergence
What Is Divergence
The signal’s given when two moving averages spread out and move away from each other. By performing analysis on this movement, we can measure the strength of the trend presented. This is done by the slope of the Value line.
The two moving averages separate because the slower moving average will not follow as quickly. The farther away these two moving averages become, the steeper the slope and the greater the divergence.
The MACD crosses the Zero Line when the 12EMA and 26EMA cross-over
Zero Line Cross-Over
What causes the Value Line to cross over the Zero Line? The Moving Averages on the price chart.
Look at the picture above, you can see that when the 12EMA and the 26EMA cross, the Value Line crosses the zero line.
The first line is called the Value Line (or the MACD Line). It’s the value of the distance between the 26EMA and the 12EMA. This measurement of the convergence and divergence between these two EMA‘s is the MACD line or the Value line.
The EMA of the Value Line is called the Avg Line. The Diff Swab is the measurement between the Value Line and the Avg Line. This is also known as the MACD Line and the MACD Average.
The Value Line is a measurement of moving averages on the price chart. The Avg Line and the Diff Swabs are internal indicators and ONLY measure the Value Line. They have nothing to do with price at all. In fact, the Avg Line and the Diff Swabs are an indicator of an indicator.
The MACD is not a “GO / NO GO” study that will offer you trade entries and trade exits. The MACD Study is designed to watch for changes in current market direction.
That’s it; current direction, impending directional change and momentum strength of the current market direction. The Value Line shows direction and the Diff Swabs show momentum.
Hence why knowing how to read MACD is important to trading the indicator.
Review of MACD Value Line, Avg Line, & Diff Histogram
Now we have a clear understanding of how to read MACD as well as where the signals come from. We may begin developing a few strategies that use these signals.
The Trend can be defined from a higher time frame.
Define the Trend
The MACD may be used to develop a bias in market direction as well as determine the trend. As a result, knowing how to read MACD can help define a trend. One way to do this effectively is to apply the MACD on a higher time frame.
As a result, the trend is determined and then take trades that go with said trend. For example, if you trade on the 4-hour chart you would want to look at the daily chart with the MACD to develop a trend bias.
If you trade on the 1 hour, you would want to set the MACD onto a 4-hour chart to determine market bias. The MACD will show trend bias with the Value Line.
Trade the Trend
This indicator has great swings above and below the Zero Line. The Value Line presents more signals than just being above or below the Avg Line. Look at the slope of the Value line and the length of the Diff Swabs.
The Avg Line tells a story of impending market trend change. On these types of trading days, it would be good to perhaps avoid trading the stock, use a lower time frame, or anticipate an uncertain market.
As a result of knowing how to read MACD, you have the ability to trade the trend as well as know when to sit out.
A signal that the trend is ending
If you know how to read MACD then you know it’s a great tool to identify when price action is range bound. When looking for an anticipation trade, the MACD can show when volatility is low, when price action is consolidating, and when momentum begins to build for an explosive move out of the contraction.
In the picture below, you can clearly see where the Diff Swabs leveled off and swapped above and below the Zero Line as price ranged in a tight pattern. These signals are very clear and offer an opportunity to anticipate a move before the breakout.

Price Action Divergence
The MACD is a great tool to identify price action divergence just by looking at the trending Value Line and the trending price. H
For instance, instead of continuously seeking divergence between price action and the MACD you
A beneficial tip; lower timeline charts have a lot of divergence signals that produce few meaningful results. This tip doesn’t apply just to the MACD but to all divergence studies in lower timelines.
The MACD Indicator Study that I’ve coded offers signals of Bearish or Bullish Divergence when price action and the MACD line disagree. You find then when you know how to read MACD. These divergences offer the trader an opportunity to develop a stock trading strategy based on an impending change in trend or momentum.
In the picture below, you see the new MACD Dialog Box with the Bullish and Bearish Divergence user settings. These signals can be turned on or off and show up on the Zero Line when a divergence is detected.
Divergence Signals will show up on the Zero Line

Trade Entry Signals
One of the great things about being an individual trader developing our own skills, abilities and opinions about market analysis and trade strategies. The more we learn and grow into our abilities, the better our analysis becomes.
The reason I don’t consider the
Can it be used as a signal for entry? Yes, however there are other tools that were designed to give such signals and do a better job. The MACD was not designed to provide entry signals.
When you first started trading you may have heard that moving average crossovers are a great trade entry signal. A lot of information suggests using
Look back over the charts after the market has closed. Compare the EMA crossovers to the market price action. You may have seen some great opportunities. However, if you tried to trade that strategy in real life, you may have found that there are fake-out signals, failed entries, or changes in direction soon after the crossover.
Using two moving averages as a signal to enter a trade at the crossover is a bad idea. The MACD is nothing more than a measurement of two moving averages.
