Crab
The Crab Pattern is a volatile 5-point extension structure that was discovered by Scott Carney in 2000. It has specific Fibonacci measurements for each point within its structure and it is important to note that D is not a point, but rather a zone in which price is likely to reverse, called the Potential Reversal Zone (PRZ). The B point retracement of the primary XA leg lies between 0.382 and 0.618 and the PRZ consists of 3 converging harmonic levels: 1) 1.618 extension of the primary XA leg, 2) AB=CD pattern, either equivalent, 1.27 or 1.618 and 3) Extreme BC projection of 2.24, 2.618, 3.14 or 3.618.

The first target would be the 382 retracement of AD and the second target the 618 retracement of AD. Common stop levels lie behind the next structure level after the D point or the 2.0 extension of XA. Conservative traders may look for additional confirmation. These patterns can be bearish and bullish . TradingView has a smart XABCD Pattern drawing tool to visually identify 5-point reversal structures on a chart.
