Table of Contents
Introduction
Stefan Jansen's "Machine Learning for Algorithmic Trading, Second Edition," stands as a beacon for those navigating the intersection of finance and artificial intelligence. This isn't just another book on trading; it's a practical roadmap for building robust, data-driven trading strategies using Python. The author meticulously guides readers through the process of extracting meaningful signals from market and alternative data, ultimately aiming to construct systematic trading models that can withstand the rigors of the real world.
Summary of the Book
The book takes you on a journey from the fundamental principles of algorithmic trading to the advanced applications of machine learning. It begins by establishing a solid foundation in Python, data handling, and basic statistical concepts. From there, Jansen dives into feature engineering, model selection, backtesting, and portfolio management. He introduces a range of machine learning algorithms, including linear models, tree-based methods, neural networks, and reinforcement learning, all within the context of trading. Crucially, the book emphasizes the importance of understanding the market microstructure, avoiding common pitfalls like overfitting, and rigorously evaluating trading strategies using robust backtesting techniques. You'll learn how to source, clean, and transform data; build predictive models to forecast price movements; and develop a comprehensive trading system that incorporates risk management and transaction cost considerations.
