We have already described many technical analysis tools on our blog. How does MACD work? We will talk about this indicator now. The MACD (‘makdi') indicator was developed almost 50 years ago by Gerald Appel. The author's premise was to create an indicator that measured the strength and direction of a trend in the stock markets.

Key Takeaways🔑

→MACD is a widely used technical analysis indicator that helps determine trend strength and potential reversals.
→The indicator consists of the MACD line, a signal line, and a bar chart (histogram).
→By observing the interactions between these components, traders can make informed decisions about market trends and potential price movements.

MACD indicator explained

MACD indicator is used to determine the current trend its strength and the probability of its reversal. It consists of the MACD line, a signal line, and the bar chart. We will discuss these 3 components of the indicator one by one.

MACD lines

The MACD line

The MACD line shows the difference between two EMA moving averages with different periods. When the MACD line crosses the zero line it indicates that there is no difference between them at this moment.

MACD line crosses zero line

The larger the difference between two moving averages the further the MACD line is from the zero line.

The signal line

The signal line is a smooth MACD line. By default, the average value of the previous nine periods is used for calculation.

The signal line act as a slow moving average which is crossed by the fast MACD.

MACD barchart

The bar chart displays the distance between the signal line and the MACD line. It changes its polarity relative to the zero line depending on the price movement direction. If the price goes upward the bar chart is above the baseline. If it goes downward the bar chart is below it. The MACD barchart is otherwise known as a histogram, as this is the type of chart it uses.

Pros and Cons 😊😞

✔️Easy to understand and use for trend analysis
✔️Applicable to various financial instruments and timeframes
❌Possible false signals in sideways or range-bound markets
❌May lag behind actual price movements due to its calculation based on moving averages

Bar Chart (Histogram) Displays the distance between the signal line and the MACD line, showing the trend direction

How do you read a MACD indicator?

To read MACD is to read the individual components of the indicator. Each component gives information about the current market situation. The standard indicator settings are 12,26 and 9. These are also the recommended settings, most traders use them and they work best.

You can change the indicator settings to set the periods for MACD and signal line moving averages which are measured in the number of candles.

When the signal line intersects the MACD line in an upward direction it indicates the possibility of price enhancement. Conversely, when the signal line intersects the MACD line in a downward direction it suggests a possible price reduction. The main advantage of the MACD indicator is its efficiency and simplicity. We encourage you to read also about combining MACD with PSAR.

How does MACD work

We have discussed all the elements of the MACD indicator today. You are now able to answer the question: How does MACD work? Let what remains be your homework. Switch on the platform, open a chart of your favourite asset and put MACD on it. Find as many intersections of the MACD with the signal line as possible. Find situations where the histogram crosses the 0 line. Observe what happens following these situations. Nothing is more instructive in technical analysis than observation. So observe and draw conclusions. Do not forget to share them in the comments below the article.
