Just a quick post in the light of a very recent event. And our favorite free historical price data provider, Yahoo , now responds on any access to their API in this way:. Without prior announcement, Yahoo has abandoned their only remaining service that was clearly ahead of the competition.
Before running the Yahoo based script, run this one:. This script downloads the data with the Google API. When you afterwards start the script with the Yahoo download, it will detect that the data is already there, and not access the Yahoo API.
So the results will be a bit different than results with Yahoo data. Like the Yahoo message, this one is also wrong, but in a more positive sense. Readers mentioned AlphaVantage www. And indeed, they provide also dividend and split adjusted data.
AlphaVantage also includes the unadjusted prices, which are sometimes required for special cases. Downloading price data from AlphaVantage and Stooq was implemented in the latest Zorro version 1. I plan on evaluating this one: Thanks for the link! The data accounts for symbol changes, splits, and dividends, and is largely free of the errors found in the Yahoo data.
Note, only symbols are available unlike Yahoo which provides all listed symbols. Reasons for all these problems: Some possible solutions are posted here: The cookie field is not for preventing robots, but for disabling all API access by software.
And Yahoo could easily counter. In times when Yahoo! Tiingo eod free https: I posed the qiestion to alphavantage about adjustment of their prices and they quickly reponded the following:. We have just beta-launched the adjusted close price feature for our daily prices API.
The API call, while not yet updated on our documentation page, should look something like:. I have shifted my scripts from pandas datareader to Intrinio data web API. Data quality is good too. Notably, it does not have mutual fund price history like Yahoo. EOD Histotrical Data https: They have similar to Yahoo! Quandl and Intrinio are good, but a little bit expensive for personal usage.
Alphavantage has very poor data for examples, without adjusted closes. One question; How can Alpha Vantage give access for free? Indeed the are not as big as Google or Yahoo. How can they sustain service costs?? This is indeed an important question, since the long-term availability of their data depends on it. Maybe Denis knows more? I am in the same worry as turtlein, After 2 months of building the system with Alphavantage, will we meet with unbearable costs?
Dear AlphaVantage, What is your profit model? Do you have a gain model? I generated that from clicking the download data from the historical data page on Yahoo. I am guessing the periods are epochs but would need to do some research to determine.
Other than that it seems straightforward to me. No cookie, no data. Problem is that it does not help to get around it. You could connect to the Yahoo main page for generating the cookie, then analyze the cookie for getting the download link. But to what avail? Besides, the data that they still provide for manual access is not comparable to their prior service — it is not anymore dividend adjusted and full of gaps.
Best substitute for real-time quotes out there I believe. Although, they could use some enabling multiple stock quote searches, everything else does a decent job for me. Wonder what alphavantage will do now that Google api is dead? Highly unlikely for it to remain free for any amount of time. I too have concern about it being a reliable long term solution since no clearly stated business model. No doubt all those Google api calls now being replaced with alphavantage so perhaps we will soon find out.
You can still pull accurate and current 5 minute, 60 minute etc. This is probably related to them pulling historic data. On a Google finance page for a given stock, there used to be a link to a table of historic data you can download. That link is gone. You can still access it via direct URL like https: I am aware of the same issue.
There are some other alternative services online such as alphavantage or quandl. I feel frustrated about being unable to subscribe multiple stocks at the same time and just to get the market snapshot. Here is an alternative service I got, which provides market snapshots: I was able to download Google Historical Data for Australia just a few days ago but now all 36 countries I download have stopped.
Has Google made an announcement? No, but Google seems to have stopped the D1 data service. The C code for downloading data from Alphavantage with Zorro:. Unable to establish SSL connection. The csv is available for download but it does not return the data for 1 year. Anyone can help me out? Sample Link for Accenture: I just written a blog post about it, please check it out: As others have mentioned above, there is a new provider of historical data since last August called Alpha Vantage.
My little contribution is that I have managed to create an Excel Addin called Deriscope that retrieves data from Alpha Vantage into Excel. It is completely free. You can download it from https: I have also exploited their intraday series, which are updated every minute, to get live stock prices into Excel with only one minute delay!
Compare that to the 20 minute delay of Yahoo Finance! A tutorial with regard to live last traded prices is https: On a Yahoo forum an administrator commenting on the error message initially stated it was a technical issue and would be fixed. On to other things.
Had a script for Yahoo prices, and it failed today…very depressing…thanks for all the notes here…my script was php … Hosting service was a faster link and has lots of disk space…but would look at python…. Alphavantage produces much more data than I need and is slower than yahoo was. I have run into one problem tracking mutual funds. It is at least 1 day behind. Their decision may be due more to risk management paranoia than anything.
Their ToS clause 22 contains some express disclaimers about the accuracy of data, which I hope we were all willing to accept. The internet went from the domain of a few scientists to a useful tool for everybody, to. Everyone should go to the FCC web site and oppose the current proposal ending net neutrality before thanksgiving. Anybody know of a workaround for this? Caught me completely by surprise.
Downloading each stock in separate url is too slow. Besides, stock history is not necessary, I only need last quotes. When writing your next doctoral thesis on how NOT to run a tech company please place asterisks next to Yahoo Inc. Discontinuation of Yahoo finance is the final straw of my use of the service service? It took all of 5 months from the time they bought Yahoo! No other firm currently offers this data via WebSocket which is especially helpful as you only need a few lines of code to implement.
