This is a book about designing, testing, and implementing trading sys¬tems for the futures and equities markets. The book begins by develop¬ing trading systems and ends by defining a system for trading. It focuses exclusively on trading systems. Hence, I have assumed that the reader has at least a working knowledge of technical analysis and is familiar with software for developing technical trading systems
The book is broadly divided into two parts. The first half deals with development and testing—how the system worked on past data— and discusses basic rules, key issues, and many new systems. The second half explores how the system might do in the future, with a focus on eq¬uity curves, risk control, and money management. A key contribution is a new method called "data scrambling," which allows unlimited amounts of synthetic data to be generated for true out-of-sample testing. The last chapter brings all of the material together by offering solutions to prac¬tical problems encountered in implementing a trading system.
