# How to Calculate And Interpret the Moving Average Convergence Divergence

## Introduction

The Moving Average Convergence Divergence (MACD) is a popular technical indicator used in financial markets, especially in technical analysis. It is primarily employed to identify potential trends, reversals, and momentum in the price of an asset.

## How to Calculate the Moving Average Convergence Divergence?

Calculating the MACD involves the following six steps.

### Step 1: Choose the Period:

Typically, the MACD is calculated using two specific periods: a shorter one (often 12 periods) and a longer one (often 26 periods). These periods can represent days, weeks, or another timeframe depending on your trading or analysis preferences.

### Step 2: Calculate the Shorter Exponential Moving Average (EMA12):

• Gather the closing prices of the asset for the specified shorter period (e.g., 12 days).
• Calculate the simple moving average (SMA) for these closing prices over the specified period.
• Apply the exponential smoothing formula to calculate the EMA for the current period:

EMA today = (Closing Price today * Smoothing Factor) + (EMA yesterday * (1 - Smoothing Factor))

• The smoothing factor for a 12-period EMA is typically 2 / (12 + 1) = 0.1538.

### Step 3: Calculate the Longer Exponential Moving Average (EMA26):

Repeat the process as you did for the shorter EMA, but this time use the closing prices for the longer period (e.g., 26 days).

### Step 4: Calculate the MACD Line:

Subtract the EMA26 value from the EMA12 value to calculate the MACD line.

MACD Line = EMA12 - EMA26

### Step 5: Calculate the Signal Line:

Calculate a 9-period EMA of the MACD line to generate the signal line.

Signal Line = 9-period EMA of MACD Line

### Step 6: Calculate the MACD Histogram:

Subtract the signal line value from the MACD line to calculate the MACD histogram.

MACD Histogram = MACD Line - Signal Line

## How to Interpret the Moving Average Convergence Divergence?

• When the MACD line goes above the signal line, it brings about a bullish signal, representing a potential uptrend.
• Conversely, when the MACD line goes below the signal line, it makes a bearish signal, proposing a potential downtrend.
• When the MACD line crosses above the signal line, it reinforces a bullish signal.
• When the MACD line crosses below the signal line, it reinforces a bearish signal.

## What are the Limitations of the Moving Average Convergence Divergence?

• MACD is a lagging indicator, meaning it relies on past price data to generate signals.
• MACD can generate false signals in choppy or sideways markets, leading to losses.
• MACD can be sensitive to short-term market noise and fluctuations.
• Traders may be tempted to adjust MACD settings to fit historical data, resulting in optimization bias.

### Conclusion

The MACD is a versatile tool that can be applied to various timeframes and financial instruments by all types of investors.
