Can anyone suggest technical analysis classes in India .
Have you checked this: https://zerodha.com/varsity/module/technical-analysis/. This is a great starting point, and after this there are many books available on this topic. Don’t know if you need class room coaching for this.
Apart from Zerodha , you can consider “INVESTAR” and link for that http://www.investarindia.com/Webinar/default.aspx
