The following chart of harmonic pattern success results is produced by FxGroundworks, and is a systematic analysis of nearly 3000 patterns.
The percentage of harmonic pattern success results for each of the harmonic patterns (Gartley, Butterfly, Crab, Bat) is over 80% for all patterns and in some cases over 90%.
Something like over 400 patterns a day are identified, typically. That's a lot of successful patterns with a predictable outcome, giving you a fantastic edge over other traders.

Although the harmonic pattern succes rates show they are 80-95% successful, it doesn't necessarily mean your trades will have the same success rate.
My trading win rate seems to vary between 60% and 75% - which is enough to be profitable of course.
Your trading success is, as always, completely dependent on how you trade it - where you enter, where you put your stops, how you react to price action during the trade, and where you exit.
But that's exactly where the harmonic methods and trading tips described in this website will help you to be successful.
