Bat pattern is primarily defined by a precise 50% retracement at the B point
1. Mandatory 50% B point retracement of the XA leg. 2. Precise 0.886 D point retracement of the XA leg as the defining limit within the PRZ. 3. 2.0 BC projection. 4. Alternate 1.27 AB=CD pattern required. 5. C point should be in the 50–61.8% range.
