Why HOOX left the VPS for Cloudflare edge isolates—Service Bindings, free-tier cost, ~22 ms median signal-to-ack. Not HFT co-lo.
Ten specialized V8 isolates, gateway pattern, Service Binding graph. Only two public surfaces; blast radius first-class.
Seven-stage signal lifecycle from TradingView webhook to fill—shared vocab for architecture, ops, and 03:00 incidents.
Durable Object mutex for at-most-once gateway acceptance—not formal exactly-once across queues and exchanges.
Service Bindings as zero-trust RPC: ~0.4–1 ms hops, no public east–west surface, auth on every internal call.
Latency claims need a measurement taxonomy first—Smart Placement, hop budgets, and honest medians over marketing.
agent-worker: cron every 5 minutes, reconcile D1 and exchanges, close positions or hit the kill switch.
D1, KV, R2, Durable Objects, Vectorize—assign each job by consistency, latency, and cost.
Five concentric security rings: edge, webhook auth, isolation, internal auth, idempotency—each with a failure mode.
Measure every hop that matters—never make the order wait for the metric. Hot-path observability done right.
One Durable Object WebSocket per exchange to amortize REST’s TCP/TLS tax—REST stays the default path.
300+ PoPs plus Smart Placement: anycast ingress, compute migrates toward exchange API proximity—not co-lo.
Design-phase Enterprise: multi-tenancy, Workflows, Logpush audit, Zero Trust—still no servers. Status 2026.
