What Readers Say About the Book
Khosrow Motalaby delivers a raw, electrifying journey into the psychology of trading. More than a thriller—The High/Low is a sobering meditation on obsession, ambition, and the illusion of control. I couldn't put it down.
This book grabs you from page one with a pulse-pounding glimpse into the world of high-stakes trading. What makes it unforgettable, though, is the emotional depth the painful, human cost of chasing perfection in an imperfect world.
Motalaby’s writing is bold, brutal, and at times, uncomfortably honest. This isn’t just about trading this is about being human in the face of risk, addiction, and the need to win. A must-read.
Motalaby captures the seductive pull of the market with chilling accuracy. If you've ever made a trade—or even just thought about it—this book will haunt you. It’s intelligent, intense, and tragically real.
