I read this book after his earlier book "Options Made Easy" ,which paved the way to get more out of this book. In addition to the well presented standard fare in options books, the author also addresses the psychological aspects which can be half the battle when trading. The examples presented were beneficial and,as a learner, the more the better. Again, a good read coupled with his earlier book.
Although it is not necessary for an option trader to understand the mathematics behind the option models used, the author does include equations which is quite helpful in my opinion. The reason for this is that any trading strategy is used more appropriately if the trader understands the math behind it.
I have had better profits selling options when volatility is high and moving lower and buying them when volatility is low and expected to go higher.
His statement "if volatility in the market continues to rise , then buying these options will be rewarded by higher premiums, provided the implied volatility of the options follows suit" seems to advocate buying options when volatility is high and expected to go higher. In my experience this is a dangerous strategy since if volatility collapses the option premiums will collapse with it and you are likely to face a loss quickly.This is especially true if you bought an option during a period of high volatility.
Also I wished the author mentioned the effect of lopsidedness in open interest between puts and calls on the likelihood of a specific option expiring worthless. I read this in another book and was amazed at the accuracy of this approach in predicting whether the puts or calls are more likely to expire worthless .

Even with the minor critical comments the book is still worth reading.

我读了这本书后，他较早的书“选项使容易”，这铺平了道路，使更多的这本书。除了在期权书中很好地介绍了标准票价，作者还谈到了心理方面，这可以是一半的战斗时，交易。所举的例子是有益的，作为一个学习者，越多越好。又是一本好书加上他以前的书。
虽然期权交易者没有必要去理解所使用的期权模型背后的数学原理，但在我看来，作者确实包含了一些非常有用的公式。其原因是，如果交易者理解其背后的数学原理，那么任何交易策略的使用都更为恰当。
我有更好的利润出售期权时，波动性高，并降低和购买时，波动性低，预计会走高。
他的声明“如果市场的波动性继续上升，那么购买这些期权将获得更高的溢价，前提是期权的隐含波动性也会随之上升”似乎主张在波动性较高且预期会走高时购买期权。根据我的经验，这是一种危险的策略，因为如果波动性崩溃，期权溢价将随之崩溃，你很可能很快面临损失。如果你在高波动期购买期权，这一点尤其正确。
我还希望作者提到看跌期权和看涨期权之间未平仓权益的不平衡性对某一特定期权失效的可能性的影响。我在另一本书中读到这一点，并惊讶于这种方法在预测看跌期权或看涨期权是否更有可能到期时一文不值的准确性。
即使有一些小的评论，这本书仍然值得一读。
