Issues with the data reader fetching yahoo finance #315

Apologies first issue/comment on GitHub. I will review proper protocol. Please correct me if this is not the correct place to put this.

Can you provide a sample that replicates your issue? This works for me:

start = datetime(2016, 12, 31)
end = datetime.now()
INPX = data.DataReader('INPX', 'yahoo', start, end)

I'm not sure what the problem was. Perhaps using 'end = datetime.today()'? You're code worked. Thank you for your help!

benpillet · 2017-05-16T20:16:06Z

From my requirements.txt:

pandas-datareader==0.4.0
pandas==0.20.1

and in python shell:

from datetime import *
import pandas_datareader.data as data
start = datetime(2016, 12, 31)
end = datetime.now()
INPX = data.DataReader('INPX', 'yahoo', start, end)

with error:

I have a feeling yahoo updated their endpoint to be something else. I get a 502 when I try curl too. The link at https://finance.yahoo.com/quote/SPY/history?p=SPY points to https://query1.finance.yahoo.com/v7/finance/download/SPY?period1=1492372898&period2=1494964898&interval=1d&events=history&crumb=MLOX17FWABw

benpillet · 2017-05-17T14:58:51Z

Looks like there's also a cookie that needs to be sent in order to avoid a 401 Unauthorized. https://www.elitetrader.com/et/threads/yahoo-historical-data-did-they-change-the-url-recently.309554/

rgkimball · 2017-05-17T18:41:00Z

Not sure if the icharts failure is a temporary problem, but I submitted a WIP PR (above) to replace the request structure. Even if icharts does come back online, may be a good idea to implement a backup.

IvanTrendafilov · 2017-05-17T21:36:00Z

I don't have the time to fix this in the library, but, essentially, there is another API endpoint that one can use. It's https://query1.finance.yahoo.com. But it requires a matching cookie and crumb to use it. I wrote a little PhantomJS script to get it, whilst I was working on it: https://github.com/IvanTrendafilov/YahooFinanceAPITokens

It can be useful to someone who needs to create a URL that they want to query automatically.

You can also get a valid cookie / crumb combination from the Chrome dev tools in the Network tab.

IvanTrendafilov · 2017-05-18T00:09:27Z

They've confirmed icharts isn't coming back, so @rgkimball's patch should certainly go in.

bkcollection · 2017-05-18T08:59:28Z

@rgkimball @IvanTrendafilov , can the fix be pip install upgrade for the ease for beginner?

Franlodo · 2017-05-18T10:26:11Z

Yahoo has change the URL, and the way the use date. Now date are Unixtime.
For example to get historic cvs from AAPL :
https://query1.finance.yahoo.com/v7/finance/download/AAPL?period1=1492510098&period2=1495102098&interval=1d&events=history&crumb=ydacXMYhzrn

period1 or period2 is date in (unixtime = (Human time - 25568) * 86400) but you must check your timezone, for example my place is Europe, then I have UTC+2 and I must sustract 7200 seconds. So my formula is (Human time - 25568) * 86400) -7200; where Human time is the time (d/mm/yyyy), 25568 is the number of days from 01/01/1900 till 01/01/1970 (This is because i do it in Excel and this is the minimun date), 86400 are the seconds in a day and 7200 are the number of seconds in my 2 hours difference with UTC

Interval is day, week or month
Events history is historic data prices, div|split&filter=split, for splits and div|split&filter=div for dividens
Crumb is the cookie ... I don't really know how it works, but I have with the same since monday.

I'm using this for update my data in Excel and it works and now I don't need to wait until morning to get the historical data because it's available at less an hour after the market close (I´m talking about american markets)

I apologyze for not to be fluent in english.

I hope this help

bkcollection · 2017-05-18T11:29:00Z

@Franlodo DO you try do download using the new link to download like 1000 stocks, will it get blocked? The old API seems has no limitation but I am curious if the new one still allow that. Hope you can try on it to validate

Franlodo · 2017-05-18T12:07:40Z

The link is to get the csv file in the web, it must run for 2 or for 2000; In my Excel file I have nearly 200 and run properly.

You can get 1000 of csv files and import from pandas, it will be the same made it saving files or "in the air"
I had post here because the error reported for pandas-datareader was the url

Anyway, I will try and comment.

rgkimball · 2017-05-18T15:08:34Z

@bkcollection This will be available once the bugs are ironed out and the pull request is merged into the main repository.

bkcollection · 2017-05-19T08:32:31Z

@rgkimball how optimistic the bugs can be fixed?

…stock still failing (pydata#315)

rgkimball · 2017-05-19T20:44:20Z

@bkcollection The latest commits of #331 about wraps it up. It's a little frustrating that the new API drops out periodically, but you can now pull any historical price range, splits and dividends. I haven't found a new interface for Yahoo Options - this may be permanently removed, but I'm happy to implement if someone finds the endpoint. Same thing for index constituents.

All of the failing tests on my PR are due to Eurostat or Yahoo's API sporadically failing. Notice that there is inconsistency across different tests for which ones are failing - appears to be random. Hoping now some other people find time pull down the code and give it a thorough review before the maintainers make a decision on merging it in.

bkcollection · 2017-05-19T23:41:09Z

How to get the implement the fix into my current module? How is the drop out happen? Can you explain more?

gusutabopb · 2017-05-21T06:15:52Z

@bkcollection:

For a temporary fix (until this PR gets merged), try:

$ git clone https://github.com/rgkimball/pandas-datareader
$ cd pandas-datareader
$ git checkout fix-yahoo
$ pip install -e .

On Python:

import pandas_datareader as pdr
print(pdr.__version__)  # Make sure it is '0.4.1'.

I originally wrote this as an answer to this Stackoverflow question

helhadry · 2017-05-21T12:57:58Z

@gusutabopb
The latest version is "0.4.0" not it?

gusutabopb · 2017-05-22T01:15:42Z

@Hmz123
The latest on master/pypi is 0.4.0. The PR proposed by @rgkimball makes it 0.4.1.
The above instructions are for those who do not want to / can't wait for an official upgrade. See the commits of the fix-yahoo patch branch here: https://github.com/rgkimball/pandas-datareader/commits/fix-yahoo

bkcollection · 2017-05-23T14:43:25Z

seems like still have some errors. Not sure when will be a fixed release 0.4.1. Hopefully in this week.

arose13 · 2017-05-23T22:53:46Z

@bkcollection what do you mean by some errors?
Do you mean being blocked by yahoo if you request a handful of symbols?

bkcollection · 2017-05-23T23:52:18Z

@arose13 you have blocked for using too many symbols? How many is it?

liuyigh · 2017-06-17T01:54:31Z

@javadba a python 2.7-compatible pull request was merged 5 days ago. FYI.

aisthesis · 2017-06-28T18:14:41Z

rgkimball's version 0.4.1 is still working for me. Is there a reason why it isn't being merged?

jreback · 2017-06-28T18:29:31Z

it needs to pass tests and respond to comments

rgkimball · 2017-06-28T18:33:44Z

I believe comments have been covered - I will try to work on tests next week. Did I miss anything? Rob Kimball Sent from my mobile device.

@m3nu Ahw. Oh really? I am just giving the facts about MarketXLS.
What is the problem about that?
You can check their forum if it really was a spam.
How can you say it is spam when you did not use MarketXLS yet?
Are you even normal or just a poser?

My replacement for the old yahoo-finance module, YahooFinancials, can get all of the historical price data needed by pandas' users. YF can return daily, weekly, and monthly historical price and volume JSON data for all stocks, ETFs, indices, cryptocurrencies, currencies, and commodity futures available on Yahoo Finance. Most Stackoverflow questions I have encountered regarding the module seem to revolve around getting it to work with Pandas. As long as Yahoo Finance is running on it's new React setup (why they killed the old API late last year, they got a new web app), my module will get the financial data.

Usage Example:

from yahoofinancials import YahooFinancials

yahoo_financials = YahooFinancials('WFC')
print(yahoo_financials.get_historical_price_data("2018-07-10", "2018-08-10", "monthly"))

Returns

{
    "WFC": {
        "currency": "USD",
        "eventsData": {
            "dividends": {
                "2018-08-01": {
                    "amount": 0.43,
                    "date": 1533821400,
                    "formatted_date": "2018-08-09"
                }
            }
        },
        "firstTradeDate": {
            "date": 76233600,
            "formatted_date": "1972-06-01"
        },
        "instrumentType": "EQUITY",
        "prices": [
            {
                "adjclose": 57.19147872924805,
                "close": 57.61000061035156,
                "date": 1533096000,
                "formatted_date": "2018-08-01",
                "high": 59.5,
                "low": 57.08000183105469,
                "open": 57.959999084472656,
                "volume": 138922900
            }
        ],
        "timeZone": {
            "gmtOffset": -14400
        }
    }
}

Anyway I'd be happy to fork a branch and build the price data from YahooFinancials into the panda-datareader's get_data_yahoo() method if you all want. I'd also be happy to work with one of your contributors to do so as well. Just let me know and I'd be happy to help!

I recently started to learn python for finance. From this thread, I understood at some level the yahoo fin package related issues but while I started to run the following code, 'ticker' not found error is persistent. Could you please check it and guide me further?

@krb1971,

The error you've shared doesn't have anything to do with the pandas datareader package. You need to define ticker before passing it into the function.

Thank you for responding. When I defined load_data as following, it did not ask for defining 'ticker'

def load_data(ticker, n_steps=50, scale=True, shuffle=True, lookup_step=1,
test_size=0.2, feature_columns=['adjclose', 'volume', 'open', 'high', 'low']):
....................

But when I use ticker below, it complains as "ticker" not defined. As I am novice to this, kindly guide.

data = load_data(ticker, N_STEPS, lookup_step=LOOKUP_STEP, test_size=TEST_SIZE, feature_columns=FEATURE_COLUMNS)

Good morning ... That's not the place for this kind of questions ... You could look for correct answers in https://bit.ly/35c8jlI or in shorturl.at/mMW47 If you add ticket = "whatever ticker stock you want" before call the función, the first part of your problem will be solved. Best regards
