这是一本极好的将option volatility 的书，在美国的option trader都看。
我看到论坛上只有没有pdf版本，所以穿了手中的pdf版本供大家参考。

关于书本的评论：
[size=13.3333339691162px]I have been a professional options trader for over 11 years. In my experience most options traders fail, and for two reasons: naive faith in mathematical models and software, and a basic misunderstanding of the concept of impled volatility.
[size=13.3333339691162px]This is the one book that everyone who has worked for me has been required to read: it is ESSENTIAL. There is no other book that covers these topics in the the way that market practitioners think about them, nor does Natenberg forget to include anything that's really useful.
[size=13.3333339691162px]I have to agreed with another reviewer: understand and study this book! Options trading is a zero-sum game. Professional traders have the edge and been earning a good living from the ill-prepared, arrogant, and naive for years.
