The book begins by discussing the operation of the financial industry and the business models of different types of Wall Street firms, as well as the job roles those with technical backgrounds can fill in those firms. Then it describes the mechanics of how these firms make money trading the main financial markets (focusing on fixed income, but also covering equity, options and derivatives markets), and highlights the ways in which quantitative professionals can participate in this money-making process. The second half focuses on the main areas of Wall Street technology and explains how financial models and systems are created, implemented, and used in real life. This is one of the few books that offers a review of relevant literature and Internet resources.

    Few, if any, of the providers or recipients of such advice can truly claim to understand the well-springs of such liquidity and the transmission mechanisms through which it impacts asset prices. This groundbreaking new book explores the belief that at the core of liquidity there is a force which exerts individuals to effect a financial transaction when they would not otherwise do so. Understanding this force of compulsion is a key to understanding a financial market when it appears to be behaving irrationally. This book will enable new and seasoned investors to develop an understanding of the factors, so that costly mistakes can be avoided without the lesson of experience.
