   Your WebSocket client

1. Our detection engine monitors exchange announcement pages continuously.
2. When a new listing is detected, it is parsed, classified, and forwarded to the dispatch server.
3. The dispatch server broadcasts the announcement to all connected WebSocket subscribers simultaneously.
4. You receive a JSON message with the ticker, exchange, listing type, and precise timestamps.

Key features

• Ultra-low latency – sub-millisecond dispatch from detection to your connection.
• Precise timestamps – microsecond-resolution timestamps at every stage (publish, detect, dispatch) so you can measure your exact latency.
• Exchange filtering – subscribe only to the exchanges you care about.
• Always-on heartbeat – know immediately if your connection drops.
• Zero-copy broadcast – announcements are serialized once and shared across all subscribers for maximum throughput.
