Real Data Setup Guide - Claude × DeepSeek Investment Advisory System

Overview

The system has been successfully upgraded to use real-time data sources instead of demo/mock data. All components are in place and tested. Follow this guide to configure real API keys for production deployment.

Current System Status

✅ Integration Complete

• Alpha Vantage data source implemented and integrated
• Forex data source (exchangerate-api.com) implemented and integrated
• Local Ollama DeepSeek support configured
• Docker environment fully configured with multi-source fallback strategy
• API endpoints tested and working

⚠️ Currently Running With Demo Keys

• ALPHA_VANTAGE_API_KEY=demo (needs real key)
• OPENEXCHANGERATES_API_KEY=demo (optional, system uses free API as fallback)
• FIXER_API_KEY=demo (optional, system uses free API as fallback)

Step 1: Get Alpha Vantage API Key (Required)

Alpha Vantage is the primary source for real stock data (US stocks, HK stocks, commodities).

Obtaining Free API Key

1. Visit: https://www.alphavantage.co/api/
2. Enter your email and get instant free API key
3. Copy your API key

Free Tier Limits

• Rate Limit: 5 requests per minute
• Total Requests: Unlimited
• Data Types: Stock quotes, intraday data, daily data, technical indicators
• Coverage: US stocks, Hong Kong stocks (HK), commodities (GC=F, SI=F, etc.)

Step 2: Get OpenExchangeRates API Key (Optional)

For forex data with priority access.

1. Visit: https://openexchangerates.org/
2. Register and get free API key
3. Copy your API key

Free Tier Limits

• Rate Limit: 1,000 requests per month
• Base Currency: USD (in free tier)

Step 3: Get Fixer.io API Key (Optional - Fallback)

Alternative forex data source.

1. Visit: https://fixer.io/
2. Register and get free API key
3. Copy your API key

Free Tier Limits

• Rate Limit: 100 requests per month
• Base Currency: EUR

Step 4: Update .env File

Update /root/work/stock/.env with your real API keys:

# ====== REQUIRED ======
# Alpha Vantage API Key for real stock data
ALPHA_VANTAGE_API_KEY=your_alpha_vantage_key_here

# ====== OPTIONAL (Forex Data) ======
# If not provided, system uses free exchangerate-api.com (unlimited)
OPENEXCHANGERATESAPI_KEY=your_openexchangerates_key_here
FIXER_API_KEY=your_fixer_key_here

# ====== REQUIRED (Already Configured) ======
OPENROUTER_API_KEY=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

# ====== LOCAL LLM (Ollama) ======
OLLAMA_BASE_URL=http://host.docker.internal:11434
DEEPSEEK_MODEL=deepseek-coder:6.7b

Step 5: Ensure Ollama is Running

The system includes local Ollama DeepSeek for quantitative analysis (no cloud calls).

On Host Machine

# Start Ollama service
ollama serve

# In another terminal, pull DeepSeek model
ollama pull deepseek-coder:6.7b

# Verify model is loaded
ollama list

Docker Configuration

The docker-compose.yml is already configured to access host Ollama:

extra_hosts:
  - "host.docker.internal:host-gateway"

This allows the container to reach Ollama at: http://host.docker.internal:11434

Step 6: Restart Docker Containers

After updating .env with real API keys:

# Rebuild and restart
docker-compose down
docker-compose up -d --build

# Wait for containers to start (30 seconds)
sleep 30

# Verify backend is healthy
curl http://localhost:8001/api/collab/health | python3 -m json.tool

Expected output:

{
  "status": "operational",
  "components": {
    "ollama": "available",
    "deepseek": "available",
    "claude": "available",
    "yahoo_finance": "available"
  },
  "timestamp": "2025-11-12T..."
}

Step 7: Test with Real Data

Test US Stock (AAPL)

curl -X POST http://localhost:8001/api/collab/recommend \
  -H "Content-Type: application/json" \
  -d '{"symbol": "AAPL"}'

Expected response:

• Real AAPL price from Alpha Vantage
• Technical indicators (SMA, RSI, MACD) calculated from real data
• DeepSeek trading signal (BUY/SELL/HOLD)
• Claude investment advice with strategies

Test Hong Kong Stock

curl -X POST http://localhost:8001/api/collab/recommend \
  -H "Content-Type: application/json" \
  -d '{"symbol": "0700.HK"}'

Test Gold/Commodity

curl -X POST http://localhost:8001/api/collab/recommend \
  -H "Content-Type: application/json" \
  -d '{"symbol": "GC=F"}'

Test Forex (EUR/USD)

curl -X POST http://localhost:8001/api/collab/recommend \
  -H "Content-Type: application/json" \
  -d '{"symbol": "EURUSD=X"}'

Data Source Priority

The system uses intelligent fallback chains:

Stock Data (Alpha Vantage)

1. Primary: Alpha Vantage (Real API key) - Real stock quotes, daily data, technical indicators
2. Fallback: Demo data with warning message

Forex Data

1. Primary: OpenExchangeRates (if API key configured)
2. Secondary: Fixer.io (if API key configured)
3. Fallback: exchangerate-api.com (free, unlimited, no auth required)

LLM Analysis

1. Primary: Local Ollama DeepSeek (quantitative analysis)
2. Fallback: Mock signal with low confidence
3. Primary: Claude Sonnet 4.5 via OpenRouter (investment advice generation)

API Rate Limits & Caching

Alpha Vantage Rate Limiting

• Hard Limit: 5 requests per minute
• System Response: Built-in 0.2s delay between requests
• Caching: 5-minute TTL for quotes and indicators
• Result: Frequent queries for same stock return cached data instantly

Forex Rate Limiting

• OpenExchangeRates: 1,000 requests/month (if API key used)
• Fixer.io: 100 requests/month (if API key used)
• exchangerate-api.com: Unlimited (free tier)
• Caching: 1-hour TTL for forex rates

Supported Asset Classes

After configuration, system supports:

Asset Class	Symbol Format	Example	Data Source
US Stocks	SYMBOL	AAPL, MSFT, NVDA	Alpha Vantage
Hong Kong Stocks	SYMBOL.HK	0700.HK (Tencent)	Alpha Vantage
Commodities	SYMBOL=F	GC=F (Gold), SI=F (Silver)	Alpha Vantage
Forex	FROM/TO=X	EURUSD=X, GBPUSD=X	Multi-source fallback

Performance Characteristics

Response Time

• Cold Cache (first request for symbol): 8-12 seconds

  • 2s: Alpha Vantage quote fetch
  • 3s: Historical data fetch
  • 2s: Technical indicator calculation
  • 3s: Ollama analysis
  • 2s: Claude advice generation

• Warm Cache (subsequent requests within 5 min): 2-3 seconds

  • Data from Redis cache
  • Ollama analysis cached

Data Freshness

• Stock quotes: Updated every 5 minutes (Alpha Vantage rate limit)
• Historical data: End-of-day updates (every business day)
• Forex rates: Updated continuously (1-hour cache)
• Technical indicators: Recalculated on each quote update

Troubleshooting

Problem: "ALPHA_VANTAGE_API_KEY is required"

Cause: .env file missing Alpha Vantage key

Solution:

# Edit .env
nano /root/work/stock/.env

# Add your real key
ALPHA_VANTAGE_API_KEY=your_key_here

# Restart containers
docker-compose down
docker-compose up -d --build

Problem: "No data for symbol"

Cause: Alpha Vantage API key invalid or rate limited

Solution:

1. Verify API key is correct: https://www.alphavantage.co/api/
2. Check you haven't exceeded 5 requests/minute limit
3. Wait for cache TTL (5 min) before retrying
4. Check backend logs: docker logs stock_backend

Problem: Ollama not available

Cause: Ollama service not running or wrong URL

Solution:

# On host machine, start Ollama
ollama serve

# Test connection from Docker
docker exec stock_backend curl http://host.docker.internal:11434/api/version

# If fails, verify docker-compose.yml has:
# extra_hosts:
#   - "host.docker.internal:host-gateway"

Problem: Forex data empty

Cause: All forex sources failing or rate limited

Solution:

1. Check if OpenExchangeRates API key is valid
2. Check if Fixer.io API key is valid
3. System will fallback to exchangerate-api.com (always free)
4. Check logs: docker logs stock_backend | grep forex

Security Notes

API Key Management

• ✅ Do: Keep API keys in .env file
• ❌ Don't: Commit .env to Git
• ✅ Do: Use environment variables in production
• ❌ Don't: Hardcode keys in source files

Production Deployment

# Before deployment, ensure:
1. .env is in .gitignore
2. Real API keys are configured
3. Ollama is accessible from backend container
4. Rate limits are monitored
5. Cache TTL values are appropriate

Next Steps

1. Get Free API Keys (5 min):

   • Alpha Vantage: https://www.alphavantage.co/api/
   • Optional: OpenExchangeRates, Fixer.io

2. Update Configuration (1 min):

   • Edit /root/work/stock/.env
   • Add your real API keys

3. Start Ollama (2 min):
