Can any one tell me all about harmonics and its patterns

Is there any site that tell me when exactly the harmonic patterns occurred for a particular stock. How do i train my self to know the patterns formed



In  NSE TAME Charts you can see the the chart patterns in nse tame website, Check the below screenshot

If you are using zerodha Pi software you have pattern recognition option under artificial intelligence menu.

Not this chart sir … Want to know more about AB=CD pattern, Bat pattern, Gartley pattern and so on . were do i find those information .?

then there is a option call <> in Zerodha pi , in pattern recognition with which you can design and customize your own patterns.
