Building a Risk-Aware Crypto Execution Queue in Node.js

Short summary

Detailed Node.js tutorial on building an idempotent trading bot execution queue that handles risk management, duplicate signal prevention, and order safety through deterministic keys and risk gates. Uses serial queue processing to prevent dangerous race conditions between concurrent trade signals. Code examples show how to separate strategy intent from execution policy, with explicit logging and audit trails.

• •Execution queue patterns prevent concurrent order placement and duplicate signals in trading systems
• •Deterministic idempotency keys and risk gates separate strategy intent from execution approval
• •Serial processing prevents race conditions and ensures audit trails for every trade decision
