download and history methods fail with proxy

[vidalmarco]

Description yFinance.dowload() and Ticker.history() methods do not work with proxy and return no data with a message like: 1 Failed download:

• AMZN: No data found for this range, symbol may be delisted

yFinance: 0.2.9 + hotfix/proxy (base.py and fundamentals.py) python: 3.9.12 OS: Windows 10 20H2

Analysis Bug is in base.py module in function history() at line 571: data = get_fn( url=url, params=params, timeout=timeout )

Fix To fix it simply add proxy=proxy as a fourth parameter.

Enjoy!! MV

We have a fix but waiting for someone to test, can you? It's broken in other places too. Git branch hotfix/proxy, instructions in #1080

Just use it normally and confirm/deny issue fixed. proxy is tricky to test because I don't have one. Try fetching history and some fundamental data like Ticker.cashflow

Hotfix works for history() and download() methods. 👍 Unfortunately it does not work for fundamentals. 👎 Example

symbol = yf.Ticker(ticker)
print("Shares:", symbol.shares)

gives a connection timeout error when creating the conn which suggests that the proxy has not taken into consideration by the Ticker object.

Given what we discussed and fixed in #1387 one way to fix this issue is the following:

1. proxy should be passed also to Ticker object at init time as an optional param and stored in self
2. (might also need to) modify all property functions of Ticker class like: get_shares(proxy=self.proxy)

From my tests above code worked well for every fundamentals property with the exception of: market_cap (not sure whether was already implemented at hotfix time) and isin (which is still experimental).

Let me know when I can test. If tests will be ok then we can close both issues.
