What is Moving Average Convergence Divergence (MACD)?
Moving Average Convergence Divergence (MACD) is a popular technical analysis indicator used to identify trend direction, momentum, and potential buy/sell signals in financial markets. It is calculated using the difference between two exponential moving averages (EMAs).
Definition
MACD is a trend-following momentum indicator that shows the relationship between two moving averages of a security’s price, typically the 12-day EMA and the 26-day EMA.
Key Takeaways
- Indicates trend direction and momentum.
- Generates signals through crossovers, divergence, and the MACD histogram.
- Widely used in stock, forex, and crypto trading.
Understanding MACD
The MACD indicator consists of three components:
- MACD Line: 12-day EMA − 26-day EMA
- Signal Line: 9-day EMA of the MACD line
- Histogram: Shows the difference between the MACD line and signal line
Traders use MACD to spot potential trend reversals or continuation signals. Common interpretations include:
- Bullish crossover: MACD line crosses above signal line
- Bearish crossover: MACD line crosses below signal line
- Divergence: Price moves in the opposite direction of MACD, signalling weakening momentum
Formula (If Applicable)
[ \text{MACD Line} = EMA_{12} – EMA_{26} ]
[ \text{Signal Line} = EMA_9(\text{MACD Line}) ]
[ \text{Histogram} = \text{MACD Line} – \text{Signal Line} ]
Real-World Example
A trader sees the MACD line cross above the signal line on a stock chart. Combined with rising volume, this signals a potential upward trend, prompting the trader to initiate a long position.
Importance in Business or Economics
MACD aids traders and investors in decision-making by helping them identify market trends, momentum shifts, and entry or exit points. It is an essential tool in market analysis and algorithmic trading.
