This book is dedicated to three very special people in my life. My wife, Kalavathi Tharp, provides a very special spark in my life. Without that spark and her tremendous love, this book would not be possible. My son, Robert Tharp, is one of the real joys in my life. He’s a trader, and he has worked very hard to understand these concepts. I’m very proud of him. And my niece, Nanthini Arumugam, has in my mind become the daughter that I always wished I would have. I am very blessed to have all of you in my life.
