The Harmonic Bat is a variation to the Gartley pattern which was developed by Scott Carney. It is considered to be one of the more accurate patterns exhibiting a higher success rate than any other harmonic patterns. The bat pattern might look similar to a Gartley 222 Butterfly pattern but differs only minutely in terms of the Fibonacci ratios between the swing/pivot points.
