The Bat pattern is a precise harmonic pattern that frequently yields exact and sharp reversals. The 0.886 retracement is a powerful completion point and the defining limit within the PRZ.
1. B point retracement of the XA leg must be less than 0.618 with a 0.50 or 0.382 retracement preferred. 2. Precise 0.886 D point retracement of the XA leg as the defining limit within the PRZ. 3. Minimum 1.618 BC projection with extreme extensions (2.0–2.618) possible. 4. Minimum AB=CD completion, although an Alternate 1.27 AB=CD is more common and preferred. 5. C point retracement can vary between a 0.382 to an 0.886.
