UPDATE : Due to copy right issues i have been asked to remove the link but you can search this book by its name and add word pdf
For all those people who are beginning their journey in stock market it is very important to know few basics of technical indicator so that you don’t enter at a wrong price. Although zerodha has done a marvelous job through “Varsity” in making people aware of the basics but journey of learning should never stop. Recently i completed reading this Book “Bollinger bands by john bollinger” and felt that it is very useful for traders like me. Made some profits too by applying what i learnt from it so i wanted to share.
