Share New Research 
import yfinance as yf
yf.Ticker("MSFT").info
> ProxyError: HTTPSConnectionPool(host='fc.yahoo.com', port=443): Max retries exceeded with url: / (Caused by ProxyError('Unable to connect to proxy', OSError('Tunnel connection failed: 403 Forbidden')))
However, using download for the same host works:
qb = QuantBook()
qb.Download("fc.yahoo.com")

To address the issue of using
yfinancein the QuantConnect research environment and encountering a proxy error, here are some suggestions and alternatives:QuantBook.download Method: The
QuantBook.downloadmethod works without proxy issues, as you've noted. This method allows you to download data directly from a specified URL, which can be a workaround for fetching data from external sources like Yahoo Finance.Alternative Data Sources: QuantConnect offers a variety of alternative datasets that can be used for universe selection and analysis. Some of these include:
These datasets can provide valuable insights and might serve as a substitute for the data you intended to fetch using
yfinance.Proxy Settings: The proxy settings in the QuantConnect research environment might be causing the issue with
yfinance. Unfortunately, these settings are not configurable by users, so using theQuantBook.downloadmethod or alternative datasets is recommended.Custom Data Sources: If you need specific data not available through QuantConnect's datasets, consider creating a custom data source. This involves defining a data class that specifies how to fetch and parse the data. An example of this is the custom Bitcoin data class that uses Quandl data.
By leveraging these alternatives and methods, you can continue your research and analysis without relying on
yfinancedirectly. If you have further questions or need assistance with implementing any of these solutions, feel free to ask!Sources: Key Concepts - QuantConnect.com, Alternative Data - QuantConnect.com, Requesting Data - QuantConnect.com
