It would be an understatement to say that the world has changed dramatically in the sixteen years since the first edition of Design, Testing, and Optimization of Trading Systems was published in 1991. With all of the changes in communications, technology, and trading styles, a thorough and comprehensive working knowledge of how to properly design and test strategies has never been more important than it has become in today s extremely competitive markets. Robert Pardo argues that a trading strategy can only be properly evaluated and successfully traded when profit and risk have been measured precisely and accurately¿which can only be done through computerized testing. In this updated and revised edition of his classic work, Pardo, a professional money manager and renowned expert in the design and testing of trading strategies and computerized trading applications, provides a clear cut and specific road map for traders who want to transform a trading idea into a tested, verified, properly capitalized, and profitable automated trading strategy.

Pardo shows that the benefits of correct testing and optimization vastly outweigh the effort required to learn and master their proper application, and sets forth in detail the correct way to formulate, test, and evaluate a trading strategy. He explains how to properly optimize a trading strategy, incorporate out of sample data in the testing of a strategy, perform Walk Forward Analysis, develop a trading strategy profile, and judge real time trading performance with respect to the trading strategy profile developed via historical testing. In addition, he identifies the symptoms of overfitting¿optimization that has "gone bad" and resulting in false conclusions and offers guidelines to avoid it.The trading game has never been as large or as lucrative as it is today. Nor have the markets ever been more efficient than they are today. Yet traders the world over continue to make profits. Why? They have found an edge. For anyone planning to employ algorithmic or mechanical strategies in their trading, this book presents, in a straightforward and accessible style, the edge that you can use to obtain and enjoy the fruits of profitable trading.
