This Yahoo Stock API is completely REST based so you can call it from anywhere, your phone, desktop whatever you like. Also being REST based means it works great with C#.

I’ve created a c# YahooStockEngine class that you can give a list of equities and it will return all the data listed above in a C# class with all those properties.
The code is very easy to understand, and really doesn’t do much but map XML to a C# class, but is very useful if your working with stocks.

I’ve included a small client called CardStock. This client is WPF and uses Model-View-ViewModel (MVVM) and displays a list of equities that it pulled from the Yahoo Finance API using YQL and REST.

    Your work is what i'm look for to develop something on my person trading. I tried getting quote ticker for stock options, but i'm not getting any pricing. Do you know where i could get that data feed?

      Not sure exactly what your looking for. But if you look at the YahooStockEngine.cs class you will see it's calling a REST based service. For example to get a quote for Apple (AAPL) it does this: http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22AAPL%22)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys The YahooStockEngine.cs also sends multiple quotes at once, but this is basically what it is doing. Once it gets the XML from that it parses it into an object. To get a new quote you need to call again to refresh.

    Well, i'm trying to get option chain quote of SPY, http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22SPY111007C00116000%22)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys which delay csv is possible at; http://download.finance.yahoo.com/d/quotes.csv?s=SPY111007C00116000&f=sl1d1t1c1ohgv&e=.csv Do you have any idea where to get this real time data. thanks there mate. :)

      Sorry but I'm not aware of a free source for real-time option data. I know you can get it with accounts at brokerages such as Interactive Brokers, but you need to setup an account and have 15k or so to set it up. Xignite is one source of the data and offer a free trial. I haven't used them myself but they look good.

    Hi, I have been exploring YQL recently, I wonder whether it can be used to get real-time (yes, I know its a delayed data) tick to tick stock quotes? I have tried and I think that YQL doesn't have any tables that stores/returns tick-to-tick stock quotes.... May be I'm wrong.. does any one have looked at it earlier? Awaiting your reply. You(admin)can also send me email. Thanks
    • Posted: November 15, 2011 19:42


      No that is not really what YQL is best at. It's basically just polling a website and scraping it in the background. You could do it yourself but with an increased frequency if that is what your really looking for. If you really want real-time stock data I would look at the BATS Exchange. I know FreeStockCharts.com uses it. (great free charting service imo.)

    Do you know how to access the after-hours data using YQL?
  • Posted: February 23, 2012 13:22


    Great Code! thanks for sharing, One quick question, if YahooStockEngine is used on a .Net app with a grid view that refreshes periodically, do I still need "PropertyChanged" ? since it's not silver light it won't refresh the UI so why use it ? Thanks again!
    • Posted: February 23, 2012 14:02


      The PropertyChanged from IPropertyNotify is only used in this case so that an ObservableCollection will be notified when an item changes. If your not using an ObservableCollection, then it is not needed and can safely be removed. You could also then change the properties to Auto-Properties.

    Hi, I'm trying to get live prices through Yahoo and I found your pages - how cool ! Only problem is that I dont seem to be getting live prices.. A query like this is showing the LastTradeTime as 15 minutes ago http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22AMZN%22)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys Additional proof is that for the first 15 minutes of the day my price is from yesterdays close.. and requests after the market is closed are still updating for 15 minutes after... I've tried this from 2 machines - 2 different IP addresses and I get the same results.. And I triued signing up for a Yahoo developer account to see if that changed things.. But no luck.. Do you think Yahoo have simply stopped their real-time price feed ? Any help you can offer is greatly appreciated. -Jason

    Yahoo login should be signed in to get realtime feed. otherwise Yahoo will provide 15 mins delays data. The request should be a web browser request with the yahoo email already signed in.

    How do I use your code on a Linux Mint 14 machine, running C/C++ with gnu compilers? Thanks.
    • Posted: January 25, 2013 20:27

      Kelly Elias

      You don't. This is c# not c++. Can probably get it working on Linux using Mono but keep in mind this complies to intermediate language (IL) and requires the .NET framework to run.

    Thanks for the information. I will make the necessary adjustments.

    I'm looking for a reliable and free 1 minute or 15 minute stock market data feed API. I'm using the Yahoo Feed but it is unstable and causes a lot of application errors. Thank You

    Thanks for your source code, if I want to have historical information of the stock details above, for example PE ratio for several quarters back or one year back, then what parameter should I add? Thank you.
    • Posted: September 10, 2015 15:30


      unfortunately, Yahoo does not provide historical series of PE; just prices & dividends. However, you can get historical data for the financial statements (up to 4 quarters), and then construct historical PE series

    I tried to use the yahoo API to query a Hong Kong stock info, but seems the dividend are not the same as the yahoo listed... the stock code is 1881.hk ... on the yahoo page is showing 0.15 (which is correct) and when I used the API to query "d" it returns 0.067 which is the value of the first dividend delivered, any help, many thanks.

    Hey, just wondering how close to real-time is yahoo finance yql? Also, this was developed many years ago, is there a new alternative to real-time stock quote now? I don't see to find anything better than this. Thanks for your work.

      It's around 5-8 minutes late. BATS exchange is a much better source. It's complete RT. Handles about 15-20% of transactions, so the volume it lists is off, but you can do the math and get it close however. Another source of RT data will be https://www.robinhood.com/ but the API is not out yet. I've asked to be in it, but it just doesn't seem to be ready yet. Very excited about this since there are $0 brokerage fees! Yeah $0! Swing traders rejoice!
