This is a book written for medium and advanced options traders. It is easy to read, but full of sophisticated information which are a result of theoretical and practical research, which are missing in many books. I am a long time subscriber to Larry's services , which are great , but Chapters 38, and 39 removed all questions and doubts , in my mind ,on stock prices and volatility trading. I highly recommend it to all options traders, and as a matter of fact, I just sent this book as a present to my son , who is still a junior options trader
