Harmonic Pattern: Bearish Gartley
The Gartley is probably the most well-known pattern in Gartley Harmonics. Gartley himself said that this pattern represents one of the best trading opportunities. Its profitability remains exceptionally resilient. This is especially true when we consider how old the pattern is and how it has remained profitable in these contemporary trading environments. Pesavento reported (at least I think he was the one who wrote this statistic) that it is profitable seven out of ten times and has remained that way for over 80 years. It is important to remember that all harmonic patterns have stringent ruleset. There is no room for interpretation in the construction of any pattern, and the Gartley pattern is no different.
