The Ultimate Algorithmic Trading System Toolbox: Using Today's Technology to Help You Become a Better Trader

By George Pruitt

Quick Summary

A practical hands-on guide to developing algorithmic trading systems using modern technology. George Pruitt, a longtime system developer, provides the code, tools, and methodology for building, testing, and deploying automated trading strategies, with emphasis on avoiding common pitfalls in system development, backtesting, and optimization.

Executive Summary

"The Ultimate Algorithmic Trading System Toolbox" is designed for traders who want to move from discretionary to systematic trading. Pruitt, who has spent decades developing trading systems and writing for the Wiley Trading series, provides a comprehensive toolkit that includes trading strategy code, backtesting frameworks, optimization techniques, and deployment guidance. The book covers the fundamentals of system design (choosing indicators, defining entry and exit rules), the critical pitfalls of backtesting (curve-fitting, survivorship bias, look-ahead bias), walk-forward optimization, portfolio-level testing, and the practical challenges of deploying systems in live markets. A companion website provides the code and tools discussed in the text. The approach is platform-agnostic in philosophy but provides specific implementations, making it accessible to traders using various software environments.
