## 4. Important Notes

1. **Encoding**: Tencent Finance API returns GBK-encoded text — decode accordingly
2. **Change %**: Use the API's built-in field (index 31) — do not calculate manually
3. **Data Delay**: Real-time data may have up to 15-minute delay
4. **Request Rate**: Avoid high-frequency requests — use batch queries when possible
5. **Error Handling**: Invalid stock codes return `v_pv_none_match="1"`
