New Trading Systems and Methods

By Perry J. Kaufman

Quick Summary

Perry Kaufman's encyclopedic reference covers virtually every known approach to systematic trading, from basic charting and trend analysis to advanced statistical methods, pattern recognition, and portfolio management. At nearly 1,000 pages, it provides detailed treatment of moving averages, momentum, regression, cycles, seasonality, spread trading, risk management, and system testing methodology.

Executive Summary

"New Trading Systems and Methods" is the definitive reference work for systematic trading, now in its fifth edition. Perry Kaufman provides exhaustive coverage of every major approach to quantifying and systematizing trading decisions. The book spans from the simplest technical indicators through advanced topics in machine learning, genetic algorithms, and neural networks. Each method is presented with mathematical foundations, practical implementation guidance, and critical evaluation of strengths and limitations.

Core Thesis

Markets exhibit exploitable patterns that can be captured through systematic rules, but no single approach works in all market conditions. Success requires understanding a wide range of methods, rigorous testing, proper risk management, and the discipline to follow a system through periods of drawdown. The book provides the tools to build, test, and evaluate trading systems across any market.

Key Concepts and Frameworks

1. Trend Following Systems -- Moving averages (simple, exponential, adaptive), channel breakouts, and momentum-based systems.
2. Mean Reversion -- Statistical methods for identifying and trading overbought/oversold conditions.
3. Pattern Recognition -- Chart patterns, candlestick patterns, and computational pattern detection.
4. Cycle Analysis -- Fourier analysis, maximum entropy spectral analysis, and seasonal patterns.
5. Risk Management -- Position sizing, portfolio heat, correlation-based diversification, and drawdown control.
6. System Testing -- Backtesting methodology, walk-forward analysis, Monte Carlo simulation, and robustness testing.
7. Adaptive Systems -- Systems that adjust parameters based on changing market conditions.

Practical Applications for Traders

1. Use the book as a reference library for evaluating and building trading systems.
2. Apply rigorous backtesting methodology before deploying any strategy.
3. Combine multiple non-correlated approaches for more robust performance.
4. Use proper position sizing as the primary risk management tool.
5. Conduct walk-forward testing to validate out-of-sample performance.

Critical Assessment

Strengths

• The most comprehensive single reference on trading systems ever published
• Mathematical rigor combined with practical implementation
• Covers virtually every approach from simple to highly advanced
• Updated regularly to reflect new methods and market conditions
• Includes extensive test results and comparative analysis

Limitations

• Encyclopedic scope means no single topic receives the depth of a dedicated book
• Can be overwhelming for beginners
• Some specific system parameters may be dated
• Heavy mathematical content may deter non-quantitative readers

Key Quotes

• "The simplest systems are the most robust."
• "A trading system is only as good as its risk management."

Conclusion
