MACD

Moving Average Convergence Divergence—a trend-following momentum indicator.

MACD (Moving Average Convergence Divergence)

MACD shows the relationship between two exponential moving averages and helps identify trend direction and momentum.

Components

  • MACD Line: 12-period EMA minus 26-period EMA
  • Signal Line: 9-period EMA of the MACD line
  • Histogram: MACD line minus signal line (visualizes the gap)

Key signals

  • Bullish crossover: MACD crosses above the signal line
  • Bearish crossover: MACD crosses below the signal line
  • Zero line cross: MACD crossing above zero indicates bullish momentum

Strengths

  • Combines trend and momentum in one indicator
  • Easy to interpret visually
  • Works across different timeframes

Weaknesses

  • Lagging indicator: Based on moving averages so signals come after the move begins
  • Can produce false signals in choppy, sideways markets
  • Best used as confirmation alongside price action, not as a standalone signal

Key Takeaways

  • Context matters when interpreting any financial metric.
  • Combine multiple data points for informed decisions.
  • Continue learning to build investment knowledge.
