The Butterfly Pattern is a distinct 5-point extension structure that was discovered by Bryce Gilmore and further defined by Scott Carney. 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 at 0.786 and the PRZ consists of 3 converging harmonic levels: 1) 1.27 extension of the primary XA leg, 2) AB=CD pattern, either equivalent or 1.27 and 3) Extreme BC projection of 2.00, 2.24 or 2.618.
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 1.41 extension of XA. Conservative traders look for additional confirmation. These patterns can be bearish and bullish.
