Review from an Amazon reader:

I've been trading Options for 7 years now. Once I realized that I needed to understand the Greeks and risk management, I started making money on a consistent basis. Pierino Ursone's book "How to Calculate Options Prices and Their Greeks" bridges the gap between Theory and real life practice. This author provides a level of math and graphs that solidifies your understanding of the Greeks. Dan Passarelli book "Trading Option Greeks" provides insight into the dynamics of the Greeks in your strategy and your risks. You can see the dynamics of the Greeks with Dan, especially on a practical level. Brian Johnson's book "Option Strategy Risk/return Ratios" provides a foundation on risk in a unique paradigm. Then you have Larry's book on Options, considered to be the bible on options. Pierino Ursone's book links all the above books. He provides just the right amount of math. For example, he provides the definition of Delta as the first derivative and the corresponding formula. He then proceeds with a graphical interpretation of delta. Then he departs from most other books and shows how Delta changes graphically with concrete and practical trading. If you as a trader are able to put the formula, the graph, the numbers together as a dynamic trade, you will see in the utility in his book. He complements Dan, Larry, and Brian. Though you may trade options without knowing the Greeks, real traders know that the Greeks shows a sensitivity to risk.
