OVERVIEW
The Waddah Attar Explosion (WAE) indicator was created by Ahmad Waddah Attar and introduced to the trading community in 2007. It combines MACD momentum measurement with Bollinger Bands volatility analysis to identify "price explosion" moments—periods when price transitions from consolidation into strong directional movement.
The indicator answers two questions:
- Is momentum building? (measured by MACD rate of change)
- Is volatility expanding? (measured by Bollinger Bands width)
When both conditions align above a noise filter (Dead Zone), it signals a potential explosive move.
COMPONENTS
1. Trend Histogram (Green/Red) Displays the rate of change of the MACD line, multiplied by a sensitivity factor.
- Calculation:
(MACD_current - MACD_previous) × Sensitivity - Green bars: Bullish momentum (MACD accelerating upward)
- Red bars: Bearish momentum (MACD accelerating downward)
- Bright color: Momentum increasing compared to previous bar
- Dark color: Momentum decreasing compared to previous bar
2. Explosion Line (White) Represents the width of the Bollinger Bands, indicating volatility expansion or contraction.
- Calculation:
BB_Upper - BB_Lower - Rising: Volatility expanding (potential breakout)
- Falling: Volatility contracting (consolidation)
3. Dead Zone (Yellow) A threshold filter to eliminate weak signals caused by market noise.
- ATR-based: Adapts to current market volatility
- Fixed Pips: Static threshold value
HOW AHMAD WADDAH ATTAR USES IT
According to the original author:
Entry Rules for Buy All conditions must be met:
- Green histogram is rising
- Green histogram is above the Explosion Line
- Explosion Line is rising
- Both green histogram and Explosion Line are above the Dead Zone
Entry Rules for Sell All conditions must be met:
- Red histogram is rising
- Red histogram is above the Explosion Line
- Explosion Line is rising
- Both red histogram and Explosion Line are above the Dead Zone
Exit Rules
- Exit long when green histogram crosses below the Explosion Line
- Exit short when red histogram crosses below the Explosion Line
Key Insight The angle of the Explosion Line matters. When the Explosion Line is angled upward and the histogram breaks above it, this confirms that volatility is actively increasing—the "explosion" is real, not a false signal.
PARAMETERS
1. Sensitivity
- Sensitivity (150): Multiplier for MACD rate of change
2. MACD
- Fast EMA Period (20): Fast moving average for MACD calculation
- Slow EMA Period (40): Slow moving average for MACD calculation
3. Bollinger Bands
- BB Period (20): Bollinger Bands lookback period
- BB Multiplier (2.0): Standard deviation multiplier
4. Dead Zone
- Dead Zone Method (ATR): Choose between ATR-based or Fixed Pips
- ATR Period (100): Period for ATR calculation
- ATR Multiplier (3.7): Multiplier applied to ATR for Dead Zone
- Fixed Dead Zone (20): Dead Zone value in pips (when using Fixed method)
NOTES
- The indicator works on all timeframes. The original author recommended H1 and M30.
- ATR-based Dead Zone is recommended as it adapts to different instruments and market conditions.
- The Sensitivity parameter may need adjustment based on timeframe and instrument volatility.
- This indicator identifies momentum and volatility alignment—it does not predict direction on its own. Consider using it alongside trend analysis or support/resistance levels.
