Reading a market in the seconds after it opens
Poly Crypto Signals reads Polymarket's short crypto markets as they open and publishes one call per window. Late is the same as wrong.
The product is a deadline. A market window opens, and the call is only worth anything while the price still is. That turns an ordinary data pipeline into something with a budget measured in seconds.
Ingest, compute and publish each have a slice of that budget, and the run is instrumented end to end so it is obvious which stage is late rather than that the whole thing is. Windows run continuously across several coins and durations, so a failure is not a single missed job, it is a gap a user will notice immediately.
Monitoring is therefore not a dashboard nobody opens. Every window either publishes inside its budget or raises an alert with the stage that missed.
What runs now: continuous ingestion of market opens, signal computation inside a per-stage latency budget, publication to the dashboard and the browser extension, and per-window monitoring that alerts on the stage that was late.
What it taught us: real-time systems fail quietly. The habit of watching every run, not every hour, is the one we bring to client processes whether they are fast or slow.
