Volatility is indicative of underlying randomness. But there are patterns within the noise that can be measured and exploited. And Euan Sinclair is a highly successful options trader with a doctorate in quantum chaos.

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.
