AB=CD Reciprocal Ratios In the AB=CD pattern, the alignment of Fibonacci ratios within the structure usually manifests specific reciprocal relationships.The reciprocal ratio of the C point retracement of the AB leg usually indicates which BC projection is utilized to define the Potential Reversal Zone (PRZ). For instance, a 0.618 retracement at the C point typically will possess a 1.618 BC projection that converges closest with the completion of the AB=CD.This reciprocal relationship within the equivalent AB=CD pattern defines the best PRZ for this structure.The reciprocal ratios that complement the AB=CD structure are as follows: C Point Retracement 0.382 0.50 0.618 0.707 0.786 0.886 BC Projection .24 or 2.618 2.0 1.618 1.41 1.27 1.13 The reciprocal ratios help define the completion of the pattern.However, the most important consideration to remember is that the BC projection should converge closely with the completion ofthe AB=CD. 4
