5-Minute Indicators: What is MACD
Series Note: This is part of our "5-Minute indicator guide" series, where we break down complex trading tools into actionable insights you can digest in one coffee break.
⚡ The Quick Summary
- What: A trend-following momentum indicator that shows the relationship between two moving averages.
- Why: It helps traders identify trend direction, strength, and potential reversal points.
- How: Use crossovers (MACD line vs. Signal line) or Divergences to find entry and exit points.
1. WHAT: The Components
The Moving Average Convergence Divergence (MACD) was developed to turn simple moving averages into a more responsive momentum tool. It consists of three moving parts:
- The MACD Line: The difference between the 12-period EMA and the 26-period EMA.
- The Signal Line: A 9-period EMA of the MACD Line itself. It acts as the "trigger."
- The Histogram: The vertical bars showing the gap between the MACD and Signal lines.
2. WHY: Why Use It?
The MACD is the "Swiss Army Knife" of technical analysis because it provides two types of data at once:
- Trend Direction: Is the market moving up or down? (Position relative to the Zero Line).
- Momentum Strength: Is the trend accelerating or slowing down? (The width of the Histogram).
Unlike a single Moving Average which only shows price direction, MACD tells you the "velocity" of the price movement.
3. HOW: The Strategy
To keep it under 5 minutes, focus on these three high-probability signals:
A. The Signal Line Crossover
- Bullish: MACD Line crosses above the Signal Line (Time to buy).
- Bearish: MACD Line crosses below the Signal Line (Time to sell).
B. The Zero-Line Crossover
- Bullish: When the MACD Line moves above the Zero Line, it confirms the short-term trend has turned positive.
- Bearish: Below the Zero Line confirms a negative trend.
C. Divergence (The "Early Warning")
- If the price hits a Higher High but the MACD hits a Lower High, the trend is losing steam and a reversal may be coming.
💡 The "Pro Tip" for This Series
Don't chase every crossover. The MACD is most effective when the market is trending. In a "sideways" or "choppy" market, the MACD will produce many "fakeouts" (false signals). Always look at the higher timeframe (e.g., Daily) to confirm the trend before taking a signal on a lower timeframe (e.g., 1-Hour).
