MACD Indicator Explained
Master the Moving Average Convergence Divergence indicator - crossovers, divergence, and proven trading strategies
What is MACD?
MACD (Moving Average Convergence Divergence) is one of the most popular technical indicators, developed by Gerald Appel in the 1970s. It reveals changes in trend strength, direction, momentum, and duration.
Unlike oscillators that move between fixed boundaries, MACD is unbounded and fluctuates around a zero line. This makes it excellent for identifying trend direction and momentum shifts.
MACD combines three elements: the MACD line, signal line, and histogram. Each provides different insights into price momentum and trend changes.
MACD Components
MACD Line (Blue)
The MACD line is calculated by subtracting the 26-period EMA from the 12-period EMA. This line shows the relationship between two moving averages and forms the core of the indicator.
Signal Line (Red/Orange)
The signal line is a 9-period EMA of the MACD line itself. Crossovers between the MACD line and signal line generate trading signals.
Histogram (Bars)
The histogram shows the difference between the MACD line and signal line. Growing bars indicate increasing momentum, shrinking bars show momentum is fading.
How to Read MACD
Above Zero Line
Bullish Territory: MACD above zero indicates the 12 EMA is above the 26 EMA - uptrend.
What it means: Short-term momentum is stronger than long-term momentum. Buyers are in control.
Trading implication: Look for long opportunities on pullbacks or signal line crosses.
Below Zero Line
Bearish Territory: MACD below zero means 12 EMA is below 26 EMA - downtrend.
What it means: Short-term momentum is weaker than long-term momentum. Sellers are in control.
Trading implication: Look for short opportunities on bounces or signal line crosses.
Increasing Histogram
Growing bars: MACD is moving away from signal line - momentum accelerating.
Green bars growing = bullish momentum increasing
Red bars growing = bearish momentum increasing
Decreasing Histogram
Shrinking bars: MACD approaching signal line - momentum slowing.
Often precedes a crossover and potential trend change
Watch for divergence when bars shrink against trend
MACD Crossover Strategy
Bullish Crossover (Buy Signal)
Occurs when the MACD line crosses above the signal line. This suggests upward momentum is building.
Bearish Crossover (Sell Signal)
Occurs when the MACD line crosses below the signal line. This suggests downward momentum is building.
MACD Divergence
Divergence between price and MACD signals potential trend reversal - one of MACD's most powerful signals.
Bullish Divergence
Pattern: Price makes a lower low, but MACD makes a higher low.
What it means: Selling pressure is weakening despite lower prices. Potential reversal to upside.
How to trade:
- 1. Identify lower low in price
- 2. Confirm MACD made higher low
- 3. Wait for bullish crossover or price break above resistance
- 4. Enter long with stop below recent low
Bearish Divergence
Pattern: Price makes a higher high, but MACD makes a lower high.
What it means: Buying pressure is weakening despite higher prices. Potential reversal to downside.
How to trade:
- 1. Identify higher high in price
- 2. Confirm MACD made lower high
- 3. Wait for bearish crossover or price break below support
- 4. Enter short with stop above recent high
MACD Settings for Different Trading Styles
| Trading Style | Settings | Timeframe | Characteristics |
|---|---|---|---|
| Standard | 12, 26, 9 | Any | Default settings, good balance for most trading |
| Day Trading | 5, 13, 1 | 5m, 15m | Faster signals, more responsive to quick moves |
| Scalping | 3, 10, 1 | 1m, 5m | Very fast signals, many crossovers |
| Swing Trading | 19, 39, 9 | 4H, Daily | Smoother signals, fewer false positives |
| Position Trading | 24, 52, 9 | Daily, Weekly | Very smooth, major trend changes only |
Test settings on your timeframe and instrument. Volatile markets may need longer periods to filter noise.
Common MACD Mistakes
Avoid These MACD Pitfalls
Common mistakes that lead to losing trades with MACD:
Combining MACD with Other Indicators
MACD + RSI
Use MACD for trend direction and RSI for overbought/oversold timing. Buy when MACD crosses up and RSI exits oversold.
MACD + Moving Averages
Add 200 EMA to filter trend. Only take MACD signals in the direction of the 200 EMA.
MACD + Support/Resistance
Wait for MACD crossover at key support/resistance levels. Confluence increases probability.
MACD + Volume
Strong volume on MACD crossover confirms signal strength. Low volume crossovers are less reliable.
MACD + Bollinger Bands
Use MACD to confirm Bollinger Band breakouts. Crossover + breakout = strong signal.
MACD + Price Action
Combine MACD signals with candlestick patterns and chart patterns for best entries.
Pro Tips for MACD Trading
Frequently Asked Questions
What is MACD in trading?
MACD (Moving Average Convergence Divergence) is a trend-following momentum indicator that shows the relationship between two moving averages (typically 12 and 26 periods). It consists of the MACD line, signal line, and histogram to identify trends and potential reversals.
What are the best MACD settings?
The default 12, 26, 9 settings work well for most trading. Day traders may use 5, 13, 1 for faster signals. Longer-term traders may use 19, 39, 9 for smoother signals. Test settings on your preferred timeframe and market.
How do you read MACD signals?
Buy when MACD line crosses above signal line (bullish crossover). Sell when MACD crosses below signal (bearish crossover). Watch for divergence between price and MACD. Histogram shows momentum strength - bigger bars mean stronger moves.
Is MACD better than RSI?
Neither is better - they serve different purposes. MACD tracks trend and momentum while RSI measures overbought/oversold conditions. Many traders use both together: MACD for trend direction and RSI for entry timing.
Can MACD be used for day trading?
Yes, MACD works well for day trading on lower timeframes (5m, 15m). Use faster settings like 5, 13, 1 for quicker signals. Combine with price action and volume for confirmation. Works best in trending markets rather than choppy ranges.
