The BodyRange State Engine (BRSE)

Financial markets are often analyzed through complex indicators and parameter-heavy models. This book introduces the BodyRange State Engine (BRSE), a systematic framework that interprets market structure using the bodies of price candles rather than conventional technical indicators. Developed through a unified program of five empirical studies, the book traces the foundations and evolution of BRSE across Bitcoin and gold markets. It examines weekly and four-hour timeframes, Japanese and Heikin-Ashi candle representations, body-defined and wick-defined structural boundaries, and long-horizon market regimes. The framework is evaluated through transparent rule-based methods, comparative testing, and robustness analysis. Particular attention is given to signal construction, exposure management, structural extensions, and the behavior of the methodology under different market conditions. Rather than presenting BRSE as a guaranteed forecasting system, this book documents it as an interpretable and reproducible research framework for studying price structure. It is intended for quantitative researchers, systematic traders, financial analysts, and readers interested in rule-based market analysis.
