Harmonic Pattern trading is based on a geometrical approach using a myriad of Fibonacci extensions, retracements and overlaps. It is important to sport Harmonic patterns before they complete as the resulting trade after completion is high probability.  The difficult issue for most traders is the knowledge and the technical skills to achieve this. Also, by the time they have made all the calculations and drawings on the chart, it could be too late. 

The Auto Harmonic Pattern Recognition software for Tradingview is designed to do all the technical stuff for traders by identifying Harmonic Patterns before they complete and labelling them.  Then it prints where the pattern should complete for the highest probability resulting trade.
