• Handling the hard parts - circuit breakers and retry logic built-in
• Real-time updates - WebSocket streaming, no polling needed
• Financial precision - Big.js eliminates floating-point errors
• AI-powered insights - Groq AI for ultra-fast market analysis

Solution: Start MongoDB

# macOS
brew services start mongodb-community

# Linux
sudo systemctl start mongod

# Docker
docker-compose up -d

Redis Connection Error

Error: connect ECONNREFUSED 127.0.0.1:6379

Solution: Start Redis

# macOS

# Linux
sudo systemctl start redis

# Docker
docker-compose up -d

AI Features Disabled

ℹ️  AI Features: DISABLED (configure GROQ_API_KEY to enable)

Solution:

1. Get API key from https://console.groq.com/keys
2. Add to .env: GROQ_API_KEY=gsk_your_key_here
3. Restart server

Circuit Breaker Open

Error: Circuit breaker is OPEN for service: alphavantage

Solutions:

• Wait 60 seconds for automatic retry
• Verify API key is valid
• Check rate limits not exceeded
• View status: /api/v1/status/circuit-breakers

Rate Limit Exceeded

Solution: Wait 15 minutes or upgrade API plan

Invalid API Key

Solution: Double-check .env file for correct keys (no quotes needed)

WebSocket Not Connecting

Solutions:

• Verify server is running
• Check firewall rules
• Ensure port is accessible
• Check browser console for errors

---

Architecture

System Overview

Client → Global-Fi Ultra → 6 External APIs
              ↓
         MongoDB + Redis

Data Flow

1. Request received
2. Check Redis cache
3. If cached, return immediately
4. If not, call external APIs (with circuit breaker protection)
5. Normalize and cache results
6. Stream to WebSocket clients
7. Return to HTTP client

Circuit Breaker Pattern

• Closed (working) - Requests flow normally
• Open (broken) - After failures, block requests temporarily
• Half-Open (testing) - After timeout, try one request to check recovery

Check status: GET /api/v1/status/circuit-breakers

Performance

Caching Strategy

• Stock data: 60 second TTL
• Crypto: 60 second TTL
• Forex: 5 minute TTL
• News: 5 minute TTL
• Economic indicators: 1 hour TTL
• AI responses: 1 hour TTL

Rate Limiting

• Global: 100 requests per 15 minutes
• Per endpoint: Varies by complexity
• WebSocket: Connection-based throttling

AI Performance

• Cached responses: < 1ms
• Simple queries (8B): 100-200ms
• Complex analysis (70B): 200-500ms
• Streaming: First token < 100ms

---

Security

Best Practices

• Never commit API keys to version control
• Use environment variables for sensitive data
• Enable CORS for specific domains only
• Implement rate limiting
• Use HTTPS in production
• Validate all inputs
• Sanitize error messages
