Foreword

In a world where trading strategies are often marketed with bold promises and little evidence, it is refreshing to encounter a book built on clarity, discipline, and data.

Tyler Liu has written a guide that stands apart. Rather than offering vague theories or unproven shortcuts, he provides a step-by-step journey that starts with the essential building blocks every trader needs: understanding stocks, ETFs, trends, and indicators. From there, he leads the reader into more advanced topics, including the thoughtful use of long-term call options and the power of data-driven strategy design.

What impressed me most about this book is its structure. The first part lays a strong foundation, ensuring that readers truly understand how the markets work before attempting to trade them. The second part moves into rigorous backtesting — not just showing when to buy and sell, but testing those ideas systematically across decades of SPY market history. Every strategy is examined, every assumption is challenged, and results are presented with honesty and transparency.

Tyler’s focus on validation over speculation is what makes this book truly valuable. Trading success is not about guessing correctly; it is about creating a repeatable, objective process that you can trust through all market conditions. This book teaches you exactly how to do that.

Whether you are a beginner eager to build strong foundations, or an experienced trader seeking a more reliable edge, you will find practical tools and insights here that can change the way you approach the markets.

I am confident that the time you invest in this book will serve you well — not just in trading, but in building the mindset required for long-term success.
