Definition
Unlike other harmonic patterns that complete closer to the original range, the Crab Pattern pushes price into extreme territory. After an initial impulse, price retraces modestly and then accelerates sharply in the original direction. This final move often reflects emotional participation, stop hunting, and late entries. As price reaches the deep Fibonacci extension zone, momentum frequently weakens, creating conditions for a sharp reversal or significant correction.
Simple Explanation
"It is the most extreme pattern. The price runs way past the highs or lows (161.8% extension), tricking everyone into thinking it is a breakout, then snaps back hard."
Core Message
- Extreme price extensions often signal exhaustion
- Late participants dominate near completion
- Fibonacci depth defines high-risk, high-reward zones
- Confirmation is mandatory before execution
Visual Interpretation
XA Leg (Impulse)
Strong directional move establishing the trend foundation.
AB Leg (Retracement)

BC Leg (Correction)

CD Leg (Extension)
Extreme extension to 161.8% of XA. Voaltile completion.
Summary
"Visually, the Crab Pattern appears stretched and aggressive. The defining feature is extreme extension into exhaustion."

Limited Pullback
