In Volatility Trading , Sinclair offers you a quantitative model for measuring volatility in order to gain an edge in your everyday option trading endeavors. With an accessible, straightforward approach. He guides traders through the basics of option pricing, volatility measurement, hedging, money management, and trade evaluation. In addition, Sinclair explains the often-overlooked psychological aspects of trading, revealing both how behavioral psychology can create market conditions traders can take advantage of-and how it can lead them astray. Psychological biases, he asserts, are probably the drivers behind most sources of edge available to a volatility trader.

Your goal, Sinclair explains, must be clearly defined and easily expressed-if you cannot explain it in one sentence, you probably aren't completely clear about what it is. The same applies to your statistical edge. If you do not know exactly what your edge is, you shouldn't trade. He shows how, in addition to the numerical evaluation of a potential trade, you should be able to identify and evaluate the reason why implied volatility is priced where it is, that is, why an edge exists. This means it is also necessary to be on top of recent news stories, sector trends, and behavioral psychology. Finally, Sinclair underscores why trades need to be sized correctly, which means that each trade is evaluated according to its projected return and risk in the overall context of your goals.

As the author concludes, while we also need to pay attention to seemingly mundane things like having good execution software, a comfortable office, and getting enough sleep, it is knowledge that is the ultimate source of edge. So, all else being equal, the trader with the greater knowledge will be the more successful. This book, and its companion CD-ROM, will provide that knowledge. The CD-ROM includes spreadsheets designed to help you forecast volatility and evaluate trades together with simulation engines.

“本书的作者为一位有着数学学术背景的交易员，书中对如何进行波动率交易所给出的简明指南充满了有价值的见解——不仅针对波动率交易员，而且也针对量化交易员。从Zakamouline关于最优delta对冲的近似方法到Browne的最优交易规模策略，书中有很多技术上的资料提供了清晰理解实践中出现问题的框架，比如：我们何时应该对冲？我们应该加仓还是减仓？我们最初应该如何将资金在交易中进行分配？本书将对数量化交易的探讨提高到了一个新的高度，因此我强烈推荐这本书。”

“我希望在我进入这个行业的时候就有期权交易方面的书籍。但是我发现我不得不费劲心思去寻找这方面的内容。本书很好地阐述了如何成功交易香草期权（又称标准期权）：合理的量化方法与稳健的理念。本书也有助于揭开波动率交易的神秘面纱：它是金融中的伏都教，令人费解、高度复杂，只有具备天赋的少数人才有能力理解和掌握。”

“尤安·辛克莱独特且有价值地洞察了期权交易中的艺术与科学。带有清晰的目的性，他向我们论述了成功的期权交易员是如何明智而审慎地选择恰当的量化工具来完成工作的——既不过于粗糙，也不过于复杂，而是在交易过程中的每一个阶段均恰到好处。我强烈推荐这本书给波动率交易员和希望窥探期权定价‘内幕’的所有使用期权的人。”
