Option Volatility Trading Strategies

This book is by Sheldon Natenberg, who wrote a famous book called Option Volatility & Pricing: Advanced Trading Strategies and Techniques (Amazon link: http://www.amazon.com/Option-Volatility-Pricing-Strategies-Techniques/dp/155738486X).

This book is super easy to read and short. I finished the book during my daily commute in 2 days. However, if you are serious about trading options, you'd better check out the book mentioned above.
