I have read a couple of books on derivatives starting from novice level. when i compare this book with those written by some of rhe other great names i feel it is much clearer andeasy to understand. It answers the questions that come to our mind. the optval library is awesome. i feel it is a must read. Coming from the man who created the Market Volatility Index (i.e., the "VIX") for the Chicago Board Options Exchange and the NASDAQ Market Volatility Index (i.e., the "VXN")it touches upon aspects of derivatives markets which serve to give the practical insight about the market's functionality.
