RYAN SCOTT WRIGHT is the founder and CEO of Raen Trading, a global proprietary trading firm and hedge fund. He is co-founder of Sentinel, a decision-intelligence platform for institutional traders, and Principal at Raen Ventures.

Wright has operated in professional trading environments for over a decade-from proprietary trading desks to hedge fund management to building his own institutional operations. He's evaluated thousands of traders, mentored hundreds more, and developed many into elite performers.

The Art and Business of Professional Trading distills the principles that actually matter at the institutional level. These aren't theories or tactics, but the cognitive frameworks every professional eventually discovers-the mental models that separate those who build careers from those who blow up.

Wright learned these truths the expensive way, through years in the markets. This book exists so you don't have to.

From Palma, Spain, Wright continues to run Raen's global operations while developing the next generation of professional traders.
