Problem: Design a Low-Latency Fixed-Income Trading Platform
Design the architecture for a high-frequency fixed-income trading system. The platform must perform the following core functions:
- Ingest live market data from multiple venues.
- Maintain a local, up-to-date market state.
- Compute trading signals based on market data.
- Execute pre-trade risk checks.
- Submit and cancel orders to various venues.
- Process order fills and acknowledgements.
The design should also incorporate:
- Audit Logs: Comprehensive logging for all critical operations.
- Monitoring: Robust systems for tracking platform health and performance.
- Fault Tolerance: Mechanisms to ensure system resilience and availability.
- Simulation, Backtesting, and Replay: Support for these capabilities to test strategies and analyze past market behavior.
You are expected to explain:
- The major components of the system.
- The critical request path for order execution.
- How to differentiate and manage latency-sensitive versus asynchronous work.
- Key deployment choices and considerations.
