Bat Pattern
A harmonic XABCD pattern with a deep AB retracement and a D point near 88.6% of XA — offering a tight stop and favorable risk/reward.
Formula
AB = 38.2%–50% of XA; BC = 38.2%–88.6% of AB; CD = 88.6% of XA
The Bat Pattern, developed by Scott Carney, has a shallower BC leg than the Gartley and a deeper D point (88.6% of XA). The tight PRZ allows for a stop just beyond X, making it one of the most capital-efficient harmonics.
The 88.6% Fibonacci level is the key ratio — it is the inverse of the square root of the golden ratio. When multiple Fibonacci levels cluster at D near 88.6% of XA, the PRZ is considered high-probability.
- AB = 38.2%–50% retracement of XA
- BC = 38.2%–88.6% of AB
- CD = 88.6% retracement of XA
