+# 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:
+
+```bash
+# ====== 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
+
+```bash
+# 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:
+
+```yaml
+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:
+
+```bash
+# 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:
+```json
+{
+  "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)
+
+```bash
+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
+
+```bash
+curl -X POST http://localhost:8001/api/collab/recommend \
+  -H "Content-Type: application/json" \
+  -d '{"symbol": "0700.HK"}'
+```
+
+### Test Gold/Commodity
+
+```bash
+curl -X POST http://localhost:8001/api/collab/recommend \
+  -H "Content-Type: application/json" \
+  -d '{"symbol": "GC=F"}'
+```
+
+### Test Forex (EUR/USD)
+
+```bash
+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 |
+

+
+## Troubleshooting
+
+### Problem: "ALPHA_VANTAGE_API_KEY is required"
+
+**Cause**: .env file missing Alpha Vantage key
+
+**Solution**:
+```bash
+# 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**:
+```bash
+# 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
+
+```bash
+# 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):
+   - Run `ollama serve` on host
+   - Pull model: `ollama pull deepseek-coder:6.7b`
+
+4. **Restart System** (1 min):
+   - Run: `docker-compose down && docker-compose up -d --build`
+
+5. **Test Real Data** (1 min):
+   - Call `/api/collab/recommend` with real stock symbols
+   - Verify real prices and analysis in response
+
+6. **Monitor Performance** (ongoing):
+   - Check backend logs for any errors
+   - Monitor API rate limits
+   - Track response times
+
+## System Architecture Summary
+
+### Components

+- **Backend**: FastAPI + Python 3.11 (port 8001)
+- **Database**: PostgreSQL (port 5433)
+- **Cache**: Redis (port 6380)
+- **LLM (Local)**: Ollama + DeepSeek (port 11434)
+- **LLM (Cloud)**: Claude 4.5 via OpenRouter
+
+### Data Sources
+
+- **Stocks**: Alpha Vantage (primary, unlimited free requests)
+- **Forex**: Multi-source fallback (OpenExchangeRates → Fixer → free API)
+- **Quantitative Analysis**: Local Ollama DeepSeek (offline)
+- **Investment Advice**: Claude Sonnet 4.5 (OpenRouter)
+
+### Key Differentiators
+
+- **No Demo Data**: Real-time market data from professional APIs
