Cant get currency from yahoo finance with matplotlib

[mushketer888]

Matplotlib cant get currency data from Yahoo Finance...
Symbol for EUR/USD is EURUSD=X.
But using this ticket it gives 404 Error.
Matplotlib version: 1.5.1

example:
quotes = quotes_historical_yahoo_ochl('EURUSD=X', date1, date2)
urllib2.HTTPError: HTTP Error 404: Not Found

Does this fail for all symbols or just this one? My two guesses are either yahoo changed the url under us or the = is going to require some extra escaping.

In either case, help sorting this out would be greatly appreciated.

I did a bit of sniffing around in finance.py:

• Doing a percent escape on the = still yielded a 404.
• 'Normal' symbols, such as AAPL still scrape fine.
• Symbols with non-alphanumeric characters like ^GSPC still scrape fine.

(This suggests that nothing is wrong with the matplotlib interface with Yahoo Finance)

By my best guess, it looks like internally, Yahoo is using a different symbol for these exchange rate symbols. So, EURUSD=X becomes EUR=X

Calling quotes_historical_yahoo_ochl('EUR=X', date1, date2) works as expected.

@bcongdon Thanks!

Closing as this does not look like a bug in mpl. @mushketer888 If you disagree and think that this is a bug in mpl please ping to have this re-opened.

Hi @tacaswell,

Seems that matplotlib fails to fetch data from yahoo Finance.

Code : just the example code in finance.py

fh = fetch_historical_yahoo('^GSPC', (2000, 1, 1), (2001, 12, 31))

Error :

HTTPError: HTTP Error 404: Not Found

Matplotlib version : 2.0.0

Maybe Yahoo changed the url format?

Can confirm with following virtualenv

 ./bin/pip list

It is likly that yahoo did change it's url.

This bug should be re-reported against https://github.com/matplotlib/mpl_finance

Looks like the Yahoo Finance's 'real-chart' subdomain is gone. (http://real-chart.finance.yahoo.com/)

Try using the method in mpl_finance, it looks like they're using the updated endpoint.
