MACD Oscillator Indicator: Facts that every Investor should know

What is MACD?

The Moving Average Convergence Divergence (MACD) helps traders spot trend changes and momentum. It shows the relationship between two moving averages of a price.

MACD Formula

MACD uses three key components:

1. MACD Line = 12-day EMA – 26-day EMA
2. Signal Line = 9-day EMA of MACD Line
3. MACD Histogram = MACD Line – Signal Line

Understanding MACD Components

MACD Line

Shows momentum by comparing short- and long-term trends.

Signal Line

Acts as a trigger for buy and sell signals.

Histogram

Displays distance between MACD and the signal line.

Pros and Cons

Advantages:

• Spot trend changes early
• Shows momentum strength
• Works in any market
• Easy to understand
• Confirms price movements

Disadvantages:

• Can give false signals
• Lags behind price
• Works best in trending markets
• Needs confirmation

Python Implementation

def calculate_macd(df, short_period=12, long_period=26, signal_period=9):
    """
    Calculate MACD, Signal line, and MACD histogram.
    
    Parameters:
    df (pd.DataFrame): DataFrame with 'close' price
    short_period (int): Short-term EMA period
    long_period (int): Long-term EMA period
    signal_period (int): Signal line period
    
    Returns:
    tuple: (MACD line, Signal line, MACD histogram)
    """
    # Calculate EMAs
    short_ema = df['close'].ewm(span=short_period, adjust=False).mean()
    long_ema = df['close'].ewm(span=long_period, adjust=False).mean()
    
    # Calculate MACD line
    macd_line = short_ema - long_ema
    
    # Calculate Signal line
    signal_line = macd_line.ewm(span=signal_period, adjust=False).mean()
    
    # Calculate MACD histogram
    macd_histogram = macd_line - signal_line
    
    return macd_line, signal_line, macd_histogram

MACD vs. RSI: Which Works Better?

While both indicators help traders, they work differently. RSI shows overbought and oversold levels, making it great for ranging markets. MACD tracks momentum and trend changes, working better in trending markets. At Meyka, our AI analyzes both indicators together for better signals.
