I treat ALL M-type or W-type patterns that have the C-point less then the A-point and the D-point less than the X-point as gartleys. This is purely based on my market research. Testing hundreds of millions of patterns absolutely atomatically I discovered that Gartleys, Bats, Leonardos aren't different patterns but variations of One pattern. I call this united pattern a Unified Gartley.
Based on my tests the D-point ratio (pattern completion - reversal) doesn't depend on the B-point ratio only. Too many factors influence the D-point (reversal): swing identification method, the B-point ratio, the C-point ratio, financial asset, timeframe, time of a pattern completion. All above mentioned variables if combined give an extremely large number of possible setups. It is impossible to test them all manually. Only automated software can digest this Big Data.
Now go back and re-read the book where authors tell you how they discovered their patterns. They printed the charts out and measured the price swings by a ruler!!! Nowdays, in our technology era they still can't confess that those discoveries were inaccurate. They register Intellectual Property thus trying to make their approach look better than it really is.
