Limitations

  • News data may have slight delays (1-5 minutes)
  • Sentiment is keyword-based, not deep NLP analysis
  • Historical data limited to recent news (last 7-14 days typically)
  • No real-time tick data (only periodic updates)

Troubleshooting

Script fails to run:

  • Ensure Python 3.7+ is installed
  • Install yfinance: pip install yfinance>=0.2.40

No news returned:

  • Check internet connection
  • Verify pair symbol is correct
  • Try different pair or reduce limit

Rate data missing:

  • Yahoo Finance API may be temporarily unavailable
  • Try again in a few minutes
