What is MACD Indicator in Stock Market?

MACD in stock market stands for Moving Average Convergence Divergence. It shows the relationship between two moving averages of a stock price. The MACD indicator is a very popular technical analysis tool that helps all traders to analyse price trends, measure momentum, and identify potential buy and sell opportunities.

The MACD is usually shown underneath the price chart and has two lines and a histogram.

How Does MACD Work?

MACD compares a shorter period EMA to a longer term EMA.

• Momentum turns positive when the short-term EMA crosses the long-term EMA.
• When the short-term EMA crosses below the long-term of EMA, the momentum is bearish.
• The difference between these two EMAs forms the MACD Line, which shows changes in the market momentum.
• The Signal Line is a moving average of the MACD Line. When the two lines cross each other, buy and sell all signals are generated.
• The Histogram shows the distance between the MACD Line and the Signal Line. As bars grow larger or smaller traders may easily see if momentum is building or fading.

How it works in practice:

When the MACD line crosses above the Signal line, it may indicate strengthening bullish momentum and is often interpreted as a potential buy signal. If it crosses above it, it might be a bullish (buy) indicator. It also helps indicate whether price momentum is strengthening or weakening.

MACD is a trend-following momentum indicator that measures the relationship between two exponential moving averages (EMAs) of a security’s price. In simple terms, it compares short-term and long-term price momentum to help identify potential trend changes and possible entry and exit points.

Components of the MACD Indicator

There are 3 main components of MACD in share market: Signal Line, MACD line and Histogram. Read more about below:

1. MACD Line

The MACD line is calculated by subtracting the 26-day EMA from the 12-day EMA.

• Positive value indicates upward momentum.
• Negative value suggests downward momentum.

2. Signal Line

• The Signal Line is the 9-day EMA of the MACD line.
• It helps traders identify potential buy and sell opportunities through crossovers.

3. Histogram

The Histogram measures the gap between MACD line and Signal Line.

• Expanding bars indicate increasing momentum.
• Shrinking bars suggest weakening momentum.

What is MACD Formula?

Here’s how to calculate MACD indicator in stock market? The standard MACD calculation is:

MACD Line = 12-day EMA − 26-day EMA

Signal Line = 9-day EMA of the MACD Line

Histogram = MACD Line − Signal Line

Most charting platforms calculate these figures automatically so traders don’t have to conduct the calculations manually.

How to Read MACD Signals?

Understanding MACD signals is essential before using it in live markets for online trading.

Bullish Crossover

A bullish crossover occurs when the MACD line crosses above the Signal Line.

This often indicates:

• Increasing buying momentum
• Potential start of an uptrend
• Possible buying opportunity

Bearish Crossover

At a certain point a bearish crossing arises when the MACD line crosses below the Signal Line. It usually means:

• Weakening momentum
• Potential downward trend
• Possible selling opportunity

Zero Line Crossover

The zero line divides the positive momentum from negative momentum.

• Above zero indicates bullish momentum.
• Below zero indicates bearish momentum.

Many traders use zero-line crossovers to confirm an existing trend.

Types of MACD Trading Signals

The following are the main types of MACD trading signals:

1. Signal Line Crossovers

The most common MACD strategy relies on the interaction between the fast MACD line and the slower signal line:

Buy Signal:

• MACD crosses above the Signal Line.

Sell Signal:

• MACD crosses below the Signal Line.

2. Zero Line Crossovers

The crossing of the zero line can be an indication that bullish momentum is starting to build. In a specific time when MACD falls below zero, it may indicate a strengthening bearish trend.

3. Divergence

Divergence occurs when the stock price and MACD move in opposite directions.

Bullish Divergence

• Price makes lower lows.
• MACD forms higher lows.
• May signal a potential upward reversal.

Bearish Divergence

• Price makes higher highs.
• MACD makes lower highs.
• May indicate weakening momentum before a decline.

Example of MACD in Indian Stock Market

Suppose the shares of a large-cap Indian company have been trading in a limited range for a few weeks. Then the MACD Line crosses up the Signal Line, the Histogram begins to grow and the MACD gets above the zero line. This combination may signal a strengthening of bullish momentum and boost the potential of a breakout if verified by increased trade volumes and good price action.

On the other hand, after a prolonged upswing the MACD Line may cross down the Signal Line while the Histogram goes negative. This can be a sign of the bullish momentum fading and there is increasing pressure to sell. All traders generally confirm these signals by examining price activity, support and resistance levels, trading volume, or other technical indicators before they decide to make a trade.
