Thriller author. Market observer. Mind hunter. 

Khosrow Motalaby writes with one foot in the world of financial strategy and the other in the darker corners of human psychology. With a deep fascination for how we risk, calculate, and self-destruct in the pursuit of power, Hoss explores what happens when obsession overrules logic. 

One man. One system. One obsession

The High/Low is a psychological thriller set against the backdrop of the stock market; a story of ambition, addiction, and the unraveling of control. When a trader builds a flawless system to outsmart the market, he thinks he’s won. But what begins as strategy quickly spirals into compulsion, as his identity gets swallowed by the game he can’t stop playing. 

If you’ve ever asked what it really means to chase success; or feared what happens when you catch it; this book will hit you where it hurts.
