Integration Examples

Update Portfolio Holdings

from skills.stock_quote.scripts.quote import fetch_yfinance_data

# Fetch current prices for all holdings
holdings = ['NVDA', 'TSLA', 'BABA', 'ORCL', 'UNH', 'AAL', 'AMZN']
quotes = fetch_yfinance_data(holdings)

# Calculate current portfolio value
total_value = sum(quote['price'] * shares for symbol, quote in quotes.items() 
                  if 'price' in quote and quote['price'])

Check Trading Rules Compliance

# Check PE ratio rule (PE > 35 blocked)
quote = fetch_yfinance_data(['NVDA'])['NVDA']
if quote.get('pe_ratio', 0) > 35:
    print("⚠️ PE ratio exceeds 35 - rule violation")

# Check 52-week percentile (above 70% blocked)
if quote.get('price') and quote.get('week_52_high') and quote.get('week_52_low'):
    percentile = (quote['price'] - quote['week_52_low']) / \
                 (quote['week_52_high'] - quote['week_52_low'])
    if percentile > 0.70:
        print("⚠️ Price above 70th percentile of 52-week range")
