The Bat Pattern is a 5-point retracement structure that was discovered by Scott Carney in 2001. 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 must be less than a 0.618, preferably a 0.50 or 0.382 and the PRZ consists of 3 converging harmonic levels: 1) 0.886 retracement of the primary XA leg, 2) extended AB=CD pattern, usually 1.27 AB=CD and 3) minimum BC projection is 1.618.
