CI/CD Pipeline for Algorithmic Trading Strategy Deployment

Construct a comprehensive GitLab CI/CD pipeline for automated testing, validation, and deployment of algorithmic trading strategies written in Python. Implement multi-stage pipeline with unit testing, integration testing, backtesting simulation, and controlled production rollout using canary deployment techniques. Include automated compliance checks for trading algorithm regulatory requirements, performance benchmarking, and automatic rollback mechanisms. The pipeline must generate comprehensive deployment reports and integrate with monitoring systems to track algorithm performance in real-time.
