Explaining the theory and practice of options from scratch, this book focuses on the practical side of options trading, and deals with hedging of options and how options traders earn money by doing so. Common terms in option theory are explained and readers are shown how they relate to profit. The book gives the necessary tools to deal with options in practice and it includes mathematical formulae to lift explanations from a superficial level. Throughout the book real-life examples will illustrate why investors use option structures to satisfy their needs.
