Could you build this?
No Building institutional-grade low-latency infrastructure connecting to 16+ market venues with normalized order books and WebSocket feeds requires high-performance systems engineering and financial exchange domain expertise.
What it would actually take: The architecture requires high-throughput WebSocket ingestion services in Rust or Go, in-memory order book normalization engines (L2/L3 books), cross-venue synchronization, and low-latency distribution pipelines. Handling exchange edge cases, rate limits, network jitter, and sub-millisecond arbitrage calculations requires specialized financial market micro-structure knowledge and dedicated distributed infra.
