This directory contains two complementary implementations of the NASDAQ Stock Market Simulator project, designed to serve different learning and deployment purposes.

Purpose: Step-by-step, phased learning approach
Audience: Students, developers learning the system architecture
Approach: Incremental development across 4 distinct phases

This directory guides you through building the NASDAQ simulator from scratch:

• Phase 1: Foundation (OMS core, basic REST API)
• Phase 2: Protocol Integration (FIX, FAST, ITCH gateways)
• Phase 3: Market Data & Risk Management
• Phase 4: Advanced Features & Production Readiness

Each phase builds upon the previous, allowing you to understand the architecture evolution and master each component before proceeding.

Purpose: Production-ready, fully integrated implementation
Audience: Deployment teams, system administrators, production users
Approach: Complete system with all features integrated

This directory contains the finished, production-ready application with all phases combined into a cohesive, optimized system ready for deployment.

cd learning-phases/
# Start with Phase 1 and progress sequentially
cd phase_1/
pip install -r requirements.txt
python main.py

cd prod-app/
# Complete system ready to run
cd phase_4/  # or whichever phase represents the full system
pip install -r requirements.txt
python main.py

• New to the project? → Start with learning-phases/
• Ready for deployment? → Use prod-app/
• Want to understand architecture? → Study learning-phases/ progression
• Need production features? → Deploy from prod-app/

Both directories maintain their own detailed README files with specific setup and usage instructions.
