The Control Plane
Execution architecture is the immune system of a trading operation. Its primary function is to isolate strategy logic from the physical constraints of the market—latency, throughput, and risk.
System Priorities
Robust systems prioritize determinism over raw speed.
- Deterministic Execution: Pre-defined paths for every order state.
- Resilient Risk: Guardrails that cannot be bypassed by strategy logic.
- Audit-Ready Observability: Full-trace logging for compliance.
Core Components
- Order Management (OMS): State management and routing logic.
- Market Data: Normalization of high-throughput feeds (CEX/DEX).
- Risk Engine: Pre-trade validation and position limit enforcement.
- Reconciliation: Post-trade settlement and reporting.
What Good Design Produces
- System Architecture: High-fidelity diagrams and technical specifications.
- Latency Profiling: Hot-path analysis and optimization plans.
- Risk Design: Validation of controls against venue constraints.
Practical Next Step
Review the current execution path, control boundaries, and rollback logic together before more strategy complexity is added.
