Unable to Extract stock data from Morningstar

[allenwu25]

I'm a beginner in python working with stock data. This morning I was able to extract stock data from the morningstar website fine, however when I try to do so now I receive the following error message shown below. What could be causing this issue and what can I do to fix it? Thanks

Found the same error : the url : http://globalquote.morningstar.com/globalcomponent/RealtimeHistoricalStockData.ashx

gives the following error

Server Error in '/GlobalComponent' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /globalcomponent/RealtimeHistoricalStockData.ashx

Looks like morningstar has changed their url for getting price quotes or there is an issue that they are working on!

Just ran into this 404 error myself.

Don't know if I should find a new method.

Or if we're supposed to wait for a new url?

This morning Morningstar still was not working, however I was able to extract data from Robinhood instead.

df=web.DataReader('MMM','robinhood', start, end)

While robinhood is able to provide stock data, the start and end dates I've set don't appear to work. The start date seems to be locked as July 31, 2017 (or 1 year from today), and the end date seems to be locked as today's date. Has anyone else tried this and had this problem?

[addisonlynch]

Seems like a provider issue. The API isn't documented (I believe it came from here), so it's difficult to tell with certainty what changes were made / if it was taken down.

For now, I would recommend using other sources such as AlphaVantage, Quandl, or IEX. The simplest is IEX, which does not require an API key

df = web.DataReader('MMM', 'IEX', start, end)

Hey I am also running into the same problem with Morningstar, was working fine but now just returns a 404 error. I tried iex as @addisonlynch suggested but it seems to have a different output format than Morningstar had as its not playing nicely with my modifiers (such as:
#name.reset_index(inplace=True)
#name.set_index('Date', inplace= True)
#name=name.drop('Symbol', axis= 1)
)
The Morningstar module worked a lot nicer
Also, I tried using robinhood as @allenwu25 suggested, but I cant seem to plot the close_price data with matplotlib from
name['close_price'].plot
as I get ...lib\site-packages\pandas\plotting\_core.py", line 373, in _compute_plot_data 'plot'.format(numeric_data.__class__.__name__)) TypeError: Empty 'DataFrame': no numeric data to plot

I have confirmation from Morningstar that this service has been discontinued, it is not a temporary outage.

[addisonlynch]

Thank you, @hubbins. We will likely mark this as deprecated for 0.7.0.
