ollama pull llama3.1:8b

# Alternative: Use a smaller model for faster processing
ollama pull llama3.1:3b

Expected outcome: Model downloads and becomes available for local inference.

Step 3: Create the Base Integration Class

import os
import requests
import pandas as pd
import json
from datetime import datetime, timedelta
from dotenv import load_dotenv
import ollama

# Load environment variables
load_dotenv()

class AlphaVantageOllamaProcessor:
    def __init__(self):
        self.api_key = os.getenv('ALPHA_VANTAGE_API_KEY')
        self.base_url = 'https://www.alphavantage.co/query'
        self.ollama_client = ollama.Client(host=os.getenv('OLLAMA_HOST'))
        
    def fetch_stock_data(self, symbol, function='GLOBAL_QUOTE'):
        """Fetch real-time stock data from Alpha Vantage"""
        params = {
            'function': function,
            'symbol': symbol,
            'apikey': self.api_key
        }
        
        try:
            response = requests.get(self.base_url, params=params)
            response.raise_for_status()
            return response.json()
        except requests.RequestException as e:

        Change Percent: {quote.get('10. change percent', 'N/A')}
        Previous Close: ${quote.get('08. previous close', 'N/A')}
        Volume: {quote.get('06. volume', 'N/A')}
        
        Provide a concise analysis covering:
        1. Price movement significance
        2. Volume analysis
        3. Short-term outlook
        4. Key risk factors
        
        Keep response under 200 words and focus on actionable insights.
        """
        
        try:
            response = self.ollama_client.chat(model='llama3.1:8b', messages=[
                {'role': 'user', 'content': analysis_prompt}

Usage Example and Implementation

Basic Stock Analysis

# Initialize the processor
processor = AlphaVantageOllamaProcessor()

# Analyze a single stock
symbol = "AAPL"
stock_data = processor.fetch_stock_data(symbol)
analysis = processor.process_stock_analysis(stock_data, symbol)

print(f"Analysis for {symbol}:")
print(analysis)

Expected output:

Analysis for AAPL:
Apple's current price of $185.42 shows a modest 1.2% gain, supported by above-average volume of 52.3M shares. The positive momentum suggests continued investor confidence, though the stock approaches resistance near $186. Short-term outlook remains bullish with strong fundamentals. Key risk: broader market volatility could impact tech sector sentiment.

Portfolio-Level Analysis

# Analyze multiple stocks
portfolio = ["AAPL", "GOOGL", "MSFT", "TSLA"]
portfolio_analysis = processor.analyze_portfolio(portfolio)

print("Portfolio Summary:")
print(portfolio_analysis)

Performance Optimization Techniques

Caching Strategy for API Efficiency

import time
from functools import lru_cache

class OptimizedProcessor(AlphaVantageOllamaProcessor):
    def __init__(self):
        super().__init__()
        self.cache_duration = 60  # Cache for 60 seconds
        self.last_request_time = {}
    
    @lru_cache(maxsize=100)
    def cached_stock_data(self, symbol, timestamp):
        """Cache stock data to reduce API calls"""
        return self.fetch_stock_data(symbol)
    
    def get_stock_data_with_cache(self, symbol):
        """Get stock data with intelligent caching"""
        current_time = time.time()
        cache_key = int(current_time // self.cache_duration)
        
        return self.cached_stock_data(symbol, cache_key)

Batch Processing for Multiple Symbols

    def batch_process_symbols(self, symbols, batch_size=5):
        """Process symbols in batches to respect API limits"""
        results = {}
        
        for i in range(0, len(symbols), batch_size):
            batch = symbols[i:i + batch_size]
            
            for symbol in batch:
                results[symbol] = self.get_stock_data_with_cache(symbol)
                time.sleep(0.2)  # Rate limiting
            
            if i + batch_size < len(symbols):
                time.sleep(12)  # Alpha Vantage rate limit buffer
        
        return results

Troubleshooting Common Integration Issues

API Rate Limit Handling

def handle_rate_limits(self, response_data):
    """Detect and handle Alpha Vantage rate limits"""
    if isinstance(response_data, dict) and 'Note' in response_data:
        if 'API call frequency' in response_data['Note']:
            print("Rate limit reached. Waiting 60 seconds...")
            time.sleep(60)
            return True
    return False

Ollama Connection Issues

def test_ollama_connection(self):
    """Verify Ollama service is running"""
    try:
        models = self.ollama_client.list()
        print(f"Ollama connected. Available models: {len(models['models'])}")
        return True
    except Exception as e:
        print(f"Ollama connection failed: {e}")
        print("Start Ollama with: ollama serve")
        return False

Data Validation and Error Handling

def validate_stock_data(self, data, symbol):
    """Validate Alpha Vantage response data"""
    if not data:
        return False, "No data received"
    
    if 'Error Message' in data:
        return False, f"API Error: {data['Error Message']}"
    
    if 'Global Quote' not in data:
        return False, "Invalid response format"
    
    quote = data['Global Quote']
    required_fields = ['05. price', '10. change percent']
    
    for field in required_fields:
        if field not in quote:
            return False, f"Missing field: {field}"
    
    return True, "Data valid"
