Waddah Attar Explosion

What is the Waddah Attar Explosion?

The Waddah Attar Explosion is a momentum-versus-volatility gate that emerged from the forex trading community, named after its creator, Waddah Attar. It plots a 'trend power' histogram, the bar-to-bar change in a MACD line scaled by a sensitivity multiplier (150 is a common default), against an 'explosion line' equal to the width between the upper and lower Bollinger Bands. Green histogram bars mark upward pressure, red bars downward. Most versions add a dead zone, a minimum threshold (fixed in some builds, ATR-derived in others) beneath which readings are treated as noise.

The logic: a move worth trading should show momentum expanding faster than the recent volatility envelope. A histogram bar rising above the explosion line (and clearing the dead zone) says directional energy exceeds ambient churn; a histogram below the line says conditions are compressed or trendless. It is a go/no-go filter with a directional color, not an entry, stop, or target system.

How traders use it

• As an entry gate for trend systems: breakout or pullback signals are taken only while the histogram exceeds both the explosion line and the dead zone, and skipped when momentum cannot clear the envelope.
• As a direction filter: green bars permit longs and red bars permit shorts, with histogram height read as the force behind the move rather than as a price objective.
• As a compression-release timer: a histogram erupting through a flat explosion line marks the turn from contraction to expansion, pairing naturally with squeeze-style setups.
