What Is Moving Average Convergence Divergence (MACD)?

MACD (Moving Average Convergence Divergence) is a trend-following momentum indicator that shows the relationship between two exponential moving averages (EMAs) of a security's price.

MACD Components:

  1. MACD Line: 12-period EMA - 26-period EMA
  2. Signal Line: 9-period EMA of the MACD Line
  3. Histogram: MACD Line - Signal Line (shows momentum)

Trading Signals:

1. Crossovers:

  • Bullish: MACD crosses above Signal Line → Buy signal
  • Bearish: MACD crosses below Signal Line → Sell signal

2. Zero Line Crossovers:

  • MACD above zero → Bullish momentum
  • MACD below zero → Bearish momentum

3. Divergences:

  • Bullish Divergence: Price makes lower low, MACD makes higher low
  • Bearish Divergence: Price makes higher high, MACD makes lower high

Strengths:

  • Combines trend and momentum analysis
  • Visually easy to interpret
  • Works well in trending markets

Limitations:

  • Lagging indicator (based on historical data)
  • Can give false signals in ranging markets
  • Whipsaws during sideways price action

Formula

Formula

MACD = 12-period EMA - 26-period EMA
