Description. The Moving Average Convergence/Divergence indicator is a momentum oscillator primarily used to trade trends. Although it is an oscillator, it is not typically used to identify over bought or oversold conditions. It appears on the chart as two lines which oscillate without boundaries.

How to interpret the MACD on a trading chart?

  • The first is the number of periods that are used to calculate the faster-moving average.
  • The second is the number of periods that are used in the slower moving average.
  • And the third is the number of bars that are used to calculate the moving average of the difference between the faster and slower moving averages.

When to use and how to read the MACD indicator?

  • Alternatively, a trader could use a break below the previous swing low or above the prior swing high to exit the trade.
  • The moving average is one of the most common indicators in the world.
  • Third, notice that the MACD formed a higher low as Google formed a lower low in November.

How to use the MACD indicator in your trading?

The MACD is a popular momentum and trend-following indicator that is based on the information of moving averages and, thus, ideal to act as an additional momentum tool and momentum filter for your trading. In this article, we will explain what the MACD indicator does, how it helps you analyze price and how to use it in your own trading.

What does MACD mean in stocks?

One extremely popular momentum trading indicator is the moving average convergence divergence (MACD) oscillator. The MACD stock indicators are used to determine the strength, direction and duration of a trend through the relationship between two moving averages.

Is MACD a good indicator?

Though invented in the seventies, MACD is still considered one of the most reliable momentum traders' indicators. As the name suggests, MACD is all about the convergence and divergence of the two moving averages.

What does a MACD chart tell you?

Moving average convergence divergence (MACD) is a trend-following momentum indicator that shows the relationship between two moving averages of a security's price.

What is MACD best used for?

Traders use the MACD to identify when bullish or bearish momentum is high in order to identify entry and exit points for trades. MACD is used by technical traders in stocks, bonds, commodities, and FX markets.

When should you buy MACD?

At its most basic level, MACD generates four signals: Buy: When the MACD line crosses above the zero line, it's bullish. Buy: When the MACD line crosses above the nine-day signal line, it's bullish. Sell: When the MACD line crosses below the zero line, it's bearish.

Is MACD good for day trading?

Though it is not useful for intraday trading, the MACD can be applied to daily, weekly, or monthly price charts. The basic MACD trading strategy uses a two-moving-averages system—one 12-period and one 26-period—along with a nine-day exponential moving average (EMA) that serves to produce clear trading signals.

How do you read a MACD strategy?

The strategy is to buy – or close a short position – when the MACD crosses above the zero line, and sell – or close a long position – when the MACD crosses below the zero line. This method should be used carefully, as the delayed nature means that fast, choppy markets would often see the signals issued too late.

What is the best indicator with MACD?

Support and resistance areas are commonly used with MACD to find price points where the trend might change direction. Candlestick chart patterns, such as the doji, can be used with moving average convergence divergence to see areas on the chart that are deemed technically significant.

Which is better MACD or RSI?

The MACD proves most effective in a widely swinging market, whereas the RSI usually tops out above the 70 level and bottoms out below 30. It usually forms these tops and bottoms before the underlying price chart. Being able to interpret their behaviour can make trading easier for a day trader.

Who invented the MACD?

The moving average convergence divergence (MACD) index was invented by Gerald Appel in the 1970s. Appel designed the MACD as a technical analysis t...

While the moving average convergence divergence (MACD) indicator measures the difference between two separate exponential moving averages (EMAs), t...

What is the best time frame for MACD?

There is no one best time frame to use the MACD index in. The MACD provides insight on potential divergence within any given time frame on a chart....

What is MACD based on?

MACD is a lagging indicator. After all, all of the data used in MACD is based on the historical price action of the stock. Since it is based on historical data, it must necessarily “lag” the price. However, some traders use MACD histograms to predict when a change in trend will occur.

Why do traders use MACD?

Traders use MACD to identify changes in the direction or severity of a stock’s price trend. MACD can seem complicated at first glance, since it relies on additional statistical concepts such as the exponential moving average (EMA).

What is a rapid rise in MACD?

When the MACD rises or falls rapidly (the shorter-term moving average pulls away from the longer-term moving average), it is a signal that the security is overbought or oversold and will soon return to normal levels.

What does it mean when the MACD is above the signal line?

As shown on the following chart, when the MACD falls below the signal line, it is a bearish signal that indicates that it may be time to sell. Conversely, when the MACD rises above the signal line, the indicator gives a bullish signal, which suggests that the price of the asset is likely to experience upward momentum. Some traders wait for a confirmed cross above the signal line before entering a position to reduce the chances of being "faked out" and entering a position too early.

What is the MACD histogram?

MACD is often displayed with a histogram (see the chart below) which graphs the distance between the MACD and its signal line. If the MACD is above the signal line, the histogram will be above the MACD’s baseline. If the MACD is below its signal line, the histogram will be below the MACD’s baseline.

What is the EMA of a 9 day MACD?

The result of that calculation is the MACD line. A nine-day EMA of the MACD called the "signal line, " is then plotted on top of the MACD line, which can function as a trigger for buy and sell signals. Traders may buy the security when the MACD crosses above its signal line and sell—or short—the security when the MACD crosses below the signal line.

What are the limitations of MACD?

Limitations of MACD. One of the main problems with divergence is that it can often signal a possible reversal but then no actual reversal actually happens—it produces a false positive. The other problem is that divergence doesn't forecast all reversals.

What is the MACD?

Interpretation. As its name implies, the MACD is all about the convergence and divergence of the two moving averages. Convergence occurs when the moving averages move towards each other. Divergence occurs when the moving averages move away from each other. The shorter moving average (12-day) is faster and responsible for most MACD movements.

Which is faster, the MACD or the longer MACD?

The shorter moving average (12-day) is faster and responsible for most MACD movements. The longer moving average (26-day) is slower and less reactive to price changes in the underlying security. The MACD line oscillates above and below the zero line, which is also known as the centerline.

How does a MACD divergence form?

Divergences form when the MACD diverges from the price action of the underlying security. A bullish divergence forms when a security records a lower low and the MACD forms a higher low. The lower low in the security affirms the current downtrend, but the higher low in the MACD shows less downside momentum. Despite decreasing, downside momentum is still outpacing upside momentum as long as the MACD remains in negative territory. Slowing downside momentum can sometimes foreshadow a trend reversal or a sizable rally.

What does a negative MACD mean?

Positive values increase as the shorter EMA diverges further from the longer EMA. This means upside momentum is increasing. Negative MACD values indicate that the 12-day EMA is below the 26-day EMA. Negative values increase as the shorter EMA diverges further below the longer EMA.

Why does MACD fluctuate above zero?

The MACD fluctuates above and below the zero line as the moving averages converge, cross and diverge. Traders can look for signal line crossovers, centerline crossovers and divergences to generate signals. Because the MACD is unbounded, it is not particularly useful for identifying overbought and oversold levels.

What is a moving average divergence oscillator?

Developed by Gerald Appel in the late seventies, the Moving Average Convergence/Divergence oscillator (MACD) is one of the simplest and most effective momentum indicators available. The MACD turns two trend-following indicators, moving averages, into a momentum oscillator by subtracting the longer moving average from the shorter one. As a result, the MACD offers the best of both worlds: trend following and momentum. The MACD fluctuates above and below the zero line as the moving averages converge, cross and diverge. Traders can look for signal line crossovers, centerline crossovers and divergences to generate signals. Because the MACD is unbounded, it is not particularly useful for identifying overbought and oversold levels.

Which is more sensitive, MACD or MACD?

Chartists looking for more sensitivity may try a shorter short-term moving average and a longer long-term moving average. MACD (5,35,5) is more sensitive than MACD (12,26,9) and might be better suited for weekly charts. Chartists looking for less sensitivity may consider lengthening the moving averages.

What is MACD in stocks?

The MACD is a technical indicator that measures the difference between bullish and bearish momentum. It helps to identify overbought and oversold conditions and trends in stocks, commodities, currencies, and other securities.

MACD indicator explanation

Moving Average Convergence Divergence is known as MACD. The main idea behind the MACD is to identify momentum shifts in a stock’s price.

How to read MACD on a trading chart?

The MACD is an indicator used for identifying trends and reversals. The 12, 26, 9 formula stood the test of time and has been widely adopted due to its effectiveness at predicting stock price movements.

How to calculate MACD

The first step is to obtain the MACD (Moving Average Convergence Divergence) indicator values. For that, we need two-time series. They can be obtained from opening price candles or previous closing candles – it’s up to you which one you will choose.

How to spot an upcoming change in trend with the MACD

As I mentioned earlier, It shows the relationship between two moving averages, one short-term and one long-term. The signal line of the MACD is simply the EMA of difference between those moving averages, which oscillates above/below zero for both bullish/bearish signals.

Using the MACD Histogram for both entry and exit

You can also use the Histogram to generate trading signals or buy/sell alerts. But divergence trading is the best way to use MACD. Now Let’s focus on the histogram position-

How to use the Moving Average Convergence Divergence as a trading strategy

Now we can dive into the MACD divergence and trading strategy. Try to avoid choosing every price pick or bottom for divergence. Instead, choose the moment when the price is going higher or lower; in other words, spot the swing high or swing low while trending.

When does the MACD histogram increase?

When a stock, future, or currency pair is moving strongly in a direction, the MACD histogram will increase in height. When the MACD histogram does not increase in height or begins to shrink, the market is slowing down and might be warning of a possible reversal.

Why is the MACD histogram shrinking?

The MACD histogram is shrinking in height. This occurs because there is a change in direction or a slowdown in the stock, future, bond, or currency trend. When that occurs, the MACD line is getting closer to the MACD signal line.

Is there a time frame for MACD?

There is no one best time frame to use the MACD index in. The MACD provides insight on potential divergence within any given time frame on a chart. The best time frame to use with the MACD depends on the type of trade, instrument, and stock that you’re interested in creating and executing a strategy for.

What is MACD stock?

The MACD stock indicators are used to determine the strength, direction and duration of a trend through the relationship between two moving averages. Sorry for the long-winded answer, but the MACD indicator throws a solid punch.

What do fundamental traders look for in a stock?

For starters, fundamental traders look at companies’ earnings announcements, cash flow statements, long-term stock charts and analysts upgrades and downgrades.

What are the most common indicators used in trading?

At this point, it’s safe to say, the most common indicators we use are momentum (RSI, MACD), trend indicators, volume, VWAP, volatility, relative volume and float.

What is fundamental trading?

Fundamental traders are the “buy and hold” investor. You may be a fundamental trader and not even know it. Likewise, if you hold long-term investments, that’s you. Maybe you have a financial planner or an investment advisor who does the fundamental analysis for you. Either way, you or your licensed financial advisor looks at ...

1. Price Growing

The stock price is in growth mode, almost doubling in the first quarter.

2. Looks for Negative Divergence

The trick with MACD is to look at the trend; it is a powerful indicator when you compare the direction of the MACD Mountains with the Price Movement.

3. The Price Declining

Here we see a sharp decline in price for the rest of 2008 until November. Using a trend line to show this helps us visualize the direction easier.

4. Looks for Positive Divergence

At the same time, the price is declining we actually see a longer-term Positive Divergence occurring from June to December. This essentially means that the “Gas in the tank of the sellers is slowly reducing.”

5. See the Buy Signal

MACD broke through the line of resistance: here we see the MACD breaking sharply past its previous high. I plotted a Trend Line in Orange to show this clearly.

Understanding the MACD Histogram

A MACD chart consists of three elements: the MACD line, a signal line, and a histogram, charted around a horizontal axis known as the baseline. The MACD chart is usually graphed just below the security's price chart, so that price movements can be compared with changes in the MACD chart.

How to Read the MACD Histogram

Traders use the MACD histogram to identify potential trend reversals and price swings. When the histogram is positive (i.e., above the baseline) that means that the MACD is higher than its nine-day average, signifying a recent increase in upward momentum. When the histogram is below the baseline, the MACD is lower than its nine-day average.

Example of MACD Histogram

The following chart demonstrates one potential way to read the MACD histogram. The top curve represents the price chart for a hypothetical security, along with a set of trendlines. The middle chart is a MACD line and histogram, centered around a baseline. The lower histogram represents the volume for each trading period.

The Bottom Line

This example should demonstrate how observing the MACD histogram can help anticipate changes in trends in both short-term and long-term price momentum. It is important for traders to learn to recognize these trends and not bet against them. Fighting a trend is a sure way to get pummeled.

What is the MACD histogram?

Like MACD, the MACD-Histogram is also an oscillator that fluctuates above and below the zero line. Aspray developed the MACD-Histogram to anticipate signal line crossovers in MACD.

How does the MACD-Histogram work?

The MACD-Histogram anticipates signal line crossovers in MACD by forming bullish and bearish divergences. These divergences signal that MACD is converging on its signal line and could be ripe for a cross. There are two types of divergences: peak-trough and slant. A peak-trough divergence forms with two peaks or two troughs in the MACD-Histogram. A peak-trough bullish divergence forms when MACD forges a lower low and the MACD-Histogram forges a higher low. Well-defined troughs are important to the robustness of a peak-trough divergence. Chart 2 shows Caterpillar with a bullish divergence in the MACD-Histogram. Notice that MACD moved to a lower low in June-July, but the MACD-Histogram formed a higher low (trough). There are two distinct troughs. This bullish divergence foreshadowed the bullish signal line crossover in mid-July and a big rally.

How to show MACD without histogram?

It is possible to show MACD without the histogram in the main window. Choose MACD as an indicator and change the signal line number from 9 to 1 (9,26,1). This will remove the signal line and the histogram. The signal line can be added separately by clicking the advanced indicator options and adding a 9-day EMA.

Why does the MACD histogram slant towards the zero line?

A MACD-Histogram slant towards the zero line reflects a convergence between MACD and its signal line. In other words, they are getting closer to each other.

Why did Aspray develop the MACD-Histogram?

Aspray developed the MACD-Histogram to anticipate signal line crossovers in MACD. Because MACD uses moving averages and moving averages lag price, signal line crossovers can come late and affect the reward-to-risk ratio of a trade.

How many steps removed is a MACD?

Four Steps Removed. The MACD-Histogram is an indicator of an indicator. In fact, MACD itself is an indicator of an indicator. This means that the MACD-Histogram is four steps removed from the price of the underlying security. In other words, it is the fourth derivative of price.

When did MACD move to a new high?

MACD moved to a new high in September, but the MACD-Histogram formed a lower high. Notice that there are two definitive peaks (higher) with a dip in between on the MACD-Histogram (red line). The subsequent bearish signal line crossover foreshadowed a sharp decline in the stock.
