Volatility, by definition, is indicative of underlying randomness. But there are patterns within the noise that can be measured and exploited. No one knows this better than author Euan Sinclair, a highly successful options trader with a doctorate in quantum chaos. But the Second Edition of Volality Trading isn't just about the numbers. Drawing upon his fifteen years as a professional trader, Sinclair provides a fully fleshed-out approach to trading that relies as much on the all-important ''human element'' and the psychological and emotional biases that drive trading decisions, as it does on quantitative analysis. Ultimately, says Sinclair, trading is about having a coherent trading philosophy and developing a rigorous system. It's about setting a goal that can be clearly expressed in one sentence, and about finding trades with a clear statistical edge. And, finally, it's about capturing that edge and sizing each trade in a way that is consistent with your goal. Everything you do as a trader must be done within this framework. Taking an accessible, straightforward approach, Sinclair provides you with the knowledge and tools you need to create just such a framework. He walks you through the basics of option pricing, volatility measurement, hedging, money management, and performance evaluation. And he develops a Black-Scholes-Merton-based quantitative model for measuring volatility that can easily can be adapted to trading virtually any type of financial instrument. Responding to major changes in the markets since the first edition, Sinclair has expanded his scope in this Second Edition to include coverage of the many new opportunities available in VIX futures, ETNs, and leveraged ETFs.
