Designing Trading Systems Volume 1
Designing Trading Systems Volume 1
Trade Booking, Lifecycle and Flow
About the Book
This book provides a comprehensive view of the fundamental components that make up a modern trading system. It focuses on the suite of applications and data flows that underpin the daily operations of a trading business, explaining how individual systems work together to form a cohesive and resilient ecosystem. Through practical insights and detailed explanations, the book explores three of the most critical functional areas within the trading landscape:
- Trade Booking – How trades are captured, represented, and persisted across systems.
- Trade Lifecycle Processing – How trades evolve through various business and system-driven events.
- Trade Data Flows – How trade information moves across applications and organizational boundaries to support risk, PnL, and reporting.
In addition to theoretical and architectural discussions, the book includes a series of case studies drawn from real-world experience. These case studies help readers navigate common implementation challenges, project decisions, and operational issues encountered in production trading environments. They serve as a hands-on guide for system architects, engineers, and technologists involved in building or maintaining trading systems. By combining conceptual clarity with practical context, this volume lays the foundation for understanding how modern trading systems are designed, integrated, and evolved to meet the demands of dynamic financial markets.
