The Fractals of Finance Determinism, Adaptation and the Geometry of Markets

Markets are not random. They are alive.

For decades, traders have profited from trends that efficient market theory says shouldn't exist. In The Fractals of Finance, Richard Brennan finally explains why.

Drawing on complexity science, information theory, and fractal geometry, Brennan reveals how price movement emerges from the same feedback mechanisms that shape rivers, galaxies, and neural networks. What appears as noise becomes geometry. What seems unpredictable reveals a deeper coherence.

This book bridges the gap between academic theory and practical trading wisdom. You'll discover:

• Why trends persist across all timeframes, and why they must
• How feedback loops generate both fat tails and long memory in markets
• The geometric structures that connect micro-scale price action to macro-scale market behaviour
• Why adaptation, not prediction, is the key to surviving and thriving in complex systems

With a foreword by Jerry Parker, one of the original Turtle Traders, The Fractals of Finance offers a new lens for understanding markets: not as machines to be predicted, but as living systems to be navigated.

Whether you're a systematic trader, a student of markets, or simply curious about why financial systems behave the way they do, this book will change how you see.
