simplejson.errors.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[Greengolfer]

I've been using yfinance for some time and was working great. All of a sudden, I am getting this error (sporadically) on the "download" when I specifically use the following:

import yfinance as yf start = 'some valid date' end = 'another valid date' data = yf.download(tickers[x], start=starting_point, end=ending_point, progress=False)

[MarkJal]

Hello! Also had the same/similar problem (first post on GitHub how about that!). I used the following:

tickers = Final_Tickers start = datetime.datetime(2018,12,27) end = datetime.datetime(2019,12,27) findata = yf.download(tickers, start=start, end=end, interval = '3mo')

Prices

price_2018 = findata['Adj Close'].iloc[0,:] price_2019 = findata['Adj Close'].iloc[-1,:]

Final_Tickers is just a list I created of stock tickers. My progress bar gets stuck at around 90% and with every progress bar there's this error:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Thanks!

Hi boys.

I can confirm this bug.

for the following code:

yf.pdr_override()

tickers = [lots of tickers here]
result = pdr.get_data_yahoo(tickers)

I tried running it via vs code, python terminal, and Jupyter, also tried with VPN, but no success. I also tried multiple times passing the same stock ticker and sometimes it would work and sometimes won't.

[Jaimindoshi]

Same boat here, and I think i know why this happens, but don't have a solution or a workaround. I think what's happening is Yahoo is probably trying to block your requests when you have multiple. I saw this by simply adding a line within the history function in base.py. BUT when i try to access the url manually, it shows up just fine.

url = "{}/v8/finance/chart/{}".format(self._base_url, self.ticker) # print (url) data = _requests.get(url=url, params=params, proxies=proxy) data.raise_for_status() if "Will be right back" in data.text: raise RuntimeError("*** YAHOO! FINANCE IS CURRENTLY DOWN! ***\n" "Our engineers are working quickly to resolve " "the issue. Thank you for your patience.") data = data.json()

Same problem. tried single symbol pulls in a loop with a pause between attempts to avoid multiple simultaneous requests, and still the error occurs.

when i then try yf.download(symbol,start=max_hist,end=today) again on the symbol that caused the error, it works.

[bstanderfer]

OK, found a solution that appears to work for me: add "threads= False" yf.download(symbol,threads= False,start=max_hist,end=today)

[Vido]

OK, found a solution that appears to work for me: add "threads= False" yf.download(symbol,threads= False,start=max_hist,end=today)

I've tried. The progress bar goes further, but it hangs.

[jhssilva]

OK, found a solution that appears to work for me: add "threads= False" yf.download(symbol,threads= False,start=max_hist,end=today)

Worked for me. Thanks!

[JaminShanti]

Was getting this today as well. I used it on Friday with no errors. Add threads= False stopped it from hanging. Was using get_data_yahoo.

[faroanalytics]

OK, found a solution that appears to work for me: add "threads= False" yf.download(symbol,threads= False,start=max_hist,end=today)

Worked for me. Thanks!

So, this works on and off for me. It may not be a permanent fix. I am running this on a simple loop:

import yfinance as yf for row in df2: try: df3 = yf.download(row, threads = False, start="2019-06-29", end="2020-06-26") df3["Ticker"] = row[0] df4 = df4.append(df3)

except: pass

first two times I ran it, it hung up. 3rd time it worked, 4th time it hung again.

It becomes more manual, but if you are running this in a Jupyter Notebook, and you get that long error message @Vido mentions, I was able to hit the "interrupt kernel" button and it would continue with the next ticker. Not optimal, just saying.

in general I don't input a list of symbols because one will randomly

unfortunately, pulling a list of names all at once never worked consistently for me. instead, i just have a list that i loop through to pull symbols individually(like your example). if it fails, then i create a list of errors and then iterate through the error list again in the end.

without threads = False the loop would fail and my script stops. with threads = False, it will continue on to the next symbol.

[JaminShanti]

In other new, I fixed my Date logic, thanks for the bug!

two_business_day_ago = (date.today() - BDay(2)).strftime("%Y-%m-%d") one_business_day_ago = (date.today() - BDay(1)).strftime("%Y-%m-%d") today = date.today().strftime("%Y-%m-%d") tomorrow = (date.today() + timedelta(days=1)).strftime("%Y-%m-%d") if datetime.now().time() > time(16,00): market_last_close_add_a_day = tomorrow compare_market_close = one_business_day_ago elif datetime.today().weekday() < 5 or datetime.today().weekday() == 0: market_last_close_add_a_day = today compare_market_close = two_business_day_ago

Seems like the unaltered code is working again for me. I've seen this issue in the past with other yahoo downloaders where something is an issue with multiple requests from Yahoo historical data, then it resolves itself in a day or two. Something must be going on with their servers when these issues happen.

[MLauer91]

If yfinance breaks again in the future I've put together a basic way to read stock data from Yahoo. This just uses built in functions within Python (tabulate is not native but can be easily replaced with just a straight print function). You can also save these dataframes to a csv by just adding the pandas function at the end of this code. https://github.com/MLauer91/Cheap-Finance-Tools/blob/master/Testing%20CSV%20Yahoo%20Finance%20Download%20(1%20Yr%20Trailing).py

I think if that happens again, I would prefer to have an application that instead of doing only requests, it too storage data and structures. That way you can easily hold the data, instead of just having the features to do requests (And of course you have the freedom to use the library the way that you want). The requests will be already set, and the structures. The data would be updated with the recursion to timers, that way you have de data up to date.

I think this is caused by the Yahoo server side.

I think this is caused by the Yahoo server side.

I'm not an expert but if this error happens to everyone at the same moment, it's maybe that.

It's strange that this happens a few days after pandas_datareader is no longer functional at all for yahoo finance...

Yes happening to me as well..

BTW, for all of us who hit this problem: is there another source other than Yahoo we can download daily US stock bars, reliably?

Not sure about you, but my same program is working yesterday (downloading hundreds of stock symbols), so I don't think it's a pandas_datareader issue. BTW I'm using pandas-datareader 0.9.0

@mingwugmail Quandl but you have to pay the subscription fee, it might be free depending on what tickers you need and how much history

Or go for alpha vantage, IEX cloud, or twelve. Tiingo also.
