The chart shows a fully qualified Gartley pattern along the current major support level (trendline). It identifies the price points that constitute the PRZ potential reversal zone.
Virtually all of harmonic patterns shown on TV don't use the techniques articulated by Carney. It's necessary to qualify the AB=CDx relationship beyond the simple 5-pointed tool provided by TV.
The following chart uses the the full suite of techniques. We see a neat, fully-qualified Gartley pattern at a major support level. I've identified the PRZ lines in orange and annotated each on the sides.
Note that the operative word in PRZ is POTENTIAL.
I personally don't trust harmonics, but this one is really clean and tempting..
