Lesson 07. MACD Indicator

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

How it works:

  1. It calculates the difference between a fast (short-term) and a slow (long-term) Exponential Moving Average (EMA).
    • Common settings: 12-period (fast) and 26-period (slow).
  2. A signal line (usually a 9-period EMA of the MACD) is plotted to show buy/sell signals.

Interpretation:

  • MACD line crosses above signal line → possible buy signal.
  • MACD line crosses below signal line → possible sell signal.
  • Histogram bars show the distance between MACD and signal line — larger bars mean stronger momentum.

In short:
MACD helps traders see trend direction, momentum strength, and potential reversals.
