The original title is: "WebSocket Reconnection That Actually Works: Auto-Reconnect Guide for Trading Bots"

Short summary

Master production-grade WebSocket reconnection for trading bots and real-time systems. Core strategies: exponential backoff with jitter to prevent thundering herd, sequence-number tracking to silently detect missed messages, and REST-based state reconciliation to fix inconsistencies. The three-layer resilience architecture covers reconnection logic, gap detection, and state recovery with exchange-specific close-code handling and recovery times from 1-2s to 5+ minutes. Includes production-ready TypeScript code.

• •Implement three-layer resilience: reconnection with exponential backoff, gap detection via sequence numbers, state recovery through REST validation
• •Handle exchange-specific close codes (1000, 1001, 1006, 1008, 1011) with different recovery strategies for each failure type
• •Production-ready TypeScript code with recovery times from 1-2s for clean disconnects to 30s-5min for extended outages
