19. What is MACD (Moving Average Convergence Divergence)?

MACD, or Moving Average Convergence Divergence, is a momentum and trend-following indicator used in technical analysis. It helps traders understand trend direction, momentum strength, and possible entry or exit points by comparing two moving averages of a stock’s price.

“MACD reveals changes in momentum before price does — making it a powerful early signal tool.”

How MACD Works

MACD is composed of three components:

ComponentWhat It Does

All values are calculated using closing prices.
