Design a highly distributed trading system.

Focus on the key components of a highly distributed trading system, including scalability, fault tolerance, and low-latency performance. Discuss the architecture, such as microservices or event-driven design, and how you would handle data consistency and synchronization across multiple nodes. Consider the technology stack you would use for real-time data processing and storage, and address how you would ensure security and compliance with financial regulations. Be prepared to explain your choices and how they impact system reliability and user experience.
