Introduction

The web service that Yahoo! provides is nice, but you have to know the right tags and symbols and how to build the URL to use it. This library will undertake that annoying task for you and returns the received data in managed classes.

This article provides the basic understanding and appliance of the library with the aid of some examples. For actual informations, releases or documentation etc. look at the project homepage.

Using the Code

Every example in this article needs the following imports:

using MaasOne;
using MaasOne.Base;

Download Classes and Namespaces

Every example in this section needs the following imports:

using MaasOne.Finance.YahooFinance;

The library provides a lot of different classes for downloading data, but with every download class it's the same principle. Each class inherits from the generic Base.DownloadClient<T> class. This class provides the basic functions for controlling the download session and getting the data. The only differences of each download class are the Settings property and the result class that is of type T. Every download class has a Settings property with a specialized settings class. This class inherits everytime from Base.SettingsBase. The result object can be of every type and stores the managed result data. There is a standardization of names in this library. E.g., if the download class is called QuotesDownload, the settings class is called QuotesDownloadSettings and the result class is called QuotesResult. Base.DownloadClient<T> class is abstract (MustInherit) so I will use Finance.YahooFinance.QuotesDownload as example.

QuotesDownload dl = new QuotesDownload();
DownloadClient<QuotesResult> baseDl = dl;

QuotesDownloadSettings settings = dl.Settings;
settings.IDs = new string[] { "MSFT", "GOOG", "YHOO" };
settings.Properties = new QuoteProperty[] { QuoteProperty.Symbol,
                                            QuoteProperty.Name, 
                                            QuoteProperty.LastTradePriceOnly
                                          };            
SettingsBase baseSettings = baseDl.Settings;

In this example you need to set the IDs of the stocks you want to get data for. And you have to set the quote properties for the data rows. SettingsBase class only provides internal functions and outside the library it's only important for standardization.

Now you can start downloading the data. For that the Base.DownloadClient<T> class provides the two methods Download and DownloadAsync. Both are parameterless and DownloadAsync provides an optional parameter for user arguments. The Download funtion returns the generic Base.Response<T>.

Response<QuotesResult> resp = baseDl.Download();

Every specialized download class like QuotesDownload can have overloaded Download and DownloadAsync methods. If you use the standard parameterless methods (userArgs is not counted as an parameter here) the class will use the Settings property object for downloading. With overloaded methods it could be that a new settings object will be created with aid of the passed parameters. Also the Settings property object could be cloned and only the passed parameters will be setted new to the cloned object.

Base.Response<T> stores the result T and the Base.ConnectionInfo. Base.ConnectionInfo class provides some information about download process like download size, needed time, success state or exceptions.

ConnectionInfo connInfo = resp.Connection;
if (connInfo.State == ConnectionState.Success)
{
    QuotesResult result = resp.Result;
    //...
}
else
{
    Exception ex = connInfo.Exception;
    Debug.WriteLine(ex.Message);
}

If you want to start an asynchronous download it's nearly the same. You can start multiple download processes with a single instance of download class. Base.DownloadClient<T> provides two events that occurs when the download process completed. The first event is the generic AsyncDownloadCompleted.

object userArgs = (double)1.5;
dl.AsyncDownloadCompleted += this.QuotesDownload_Completed;
dl.DownloadAsync(userArgs);

private void QuotesDownload_Completed(DownloadClient<QuotesResult> sender, 
                                      DownloadCompletedEventArgs<QuotesResult> e)
{
    sender.AsyncDownloadCompleted -= this.QuotesDownload_Completed;

    object userArgs = e.UserArgs;
    double dbl = (double)userArgs;

    SettingsBase baseSettings = e.Settings;
    QuotesDownloadSettings settings = (QuotesDownloadSettings)baseSettings;

    Response<QuotesResult> resp = e.Response;
    QuotesResult result = resp.Result;
    //...
}

The delegate passes the DownloadCompletedEventArgs<T>. This class provides passed user arguments, used settings and the response with connection info and result data, etc. The settings will be cloned before the download started. So, if the settings of download object changed during async downloading, the settings of event args will have original values of current download process.

The second event is the non-generic AsyncDownloadCompletedEvent and is implemented by IDownload interface. IDownload is nearly as powerfull as DownloadClient<T>, without the generic part.

object userArgs = (double)1.5;
dl.AsyncDownloadCompletedEvent += this.IDownload_Completed;
dl.DownloadAsync(userArgs);

private void IDownload_Completed(IDownload sender, IDownloadCompletedEventArgs e) 
{
    sender.AsyncDownloadCompletedEvent -= this.IDownload_Completed;

    object userArgs = e.UserArgs;
    double dbl = (double)userArgs;

    SettingsBase baseSettings = e.Settings;
    QuotesDownloadSettings settings = (QuotesDownloadSettings)baseSettings;

    IResponse resp = e.GetResponse();
    object baseResult = resp.GetObjectResult();
    QuotesResult result = (QuotesResult)baseResult;
    //...
}

In this example I used the Finance.YahooFinance.QuotesDownload class. With help of the following overview you can see the most specialized download classes of this library.

  • Finance.YahooFinance
    • AlphabeticIDIndexDownload: Downloads valid Yahoo! Finance IDs by index (A-Z).
    • ChartDownload: Downloads technical analyzing charts.
    • CompanyInfoDownload: Downloads main informations of companies.
    • CompanyProfileDownload: Downloads profile data of companies.
    • CompanyStatisticsDownload: Downloads financial statistics of companies.
    • FuturesChainDownload: Downloads future chains.
    • HistQuotesDownload: Downloads historic quotes.
    • IDSearchDownload: Searches for valid Yahoo! Finance IDs by keyword.
    • MarketDownload: Downloads market overview with sectors, industries and containing companies.
    • MarketQuotesDownload: Downloads the market quotes of a sector, industry or containing company.
    • QuotesDownload: Downloads up to 85 quote properties.
    • QuoteOptionsDownload: Downloads put and pull options.
  • Finance.YahooPortfolio
    • YPortfolioManager: Manages your Yahoo! portfolios (create, edit and delete portfolios, views and components).
    • HoldingsDownload: Downloads holdings data.
    • PortfolioInfoDownload: Downloads an array of all portfolios without components.
    • PortfolioDownload: Downloads the components of a portfolio view.
  • Finance.YahooScreener
    • BondScreenerDownload: Monitors bonds by specific criterias.
    • StockScreenerDownload: Monitors stocks by specific criterias
  • Search.BOSS
    • SearchDownload: Downloads search query data for web, image, news and spelling service.

  • Geo.GeoPlanet
    • PlacesDownload: Downloads geo data with Geo Planet API (deprecated by Yahoo!).
  • Geo.PlaceFinder
    • PlaceFinderDownload: Downloads geo data with Place Finder API.
  • Weather.YahooWeather
    • LocationIDSearchDownload: Downloads Location IDs for Weather API.
    • WeatherFeedDownload: Downloads weather forecast.

Additionally to these Yahoo! namespaces there is also the RSS namespace. Some web services provides RSS feeds and this class can be used to download RSS 2.0 feeds.

  • RSS
    • FeedDownload: Downloads RSS 2.0 feeds.

This project started with wrapping Yahoo! web services but can also be extended for other web services. At this time there exists an implementation for MSN Money (Microsoft).

  • Finance.MSNMoney
    • ChartDownload: Downloads technical analyzing charts.
    • HistQuotesDownload: Downloads historic quotes.
    • IDSearchDownload: Searches for valid Yahoo! Finance IDs by keyword.
    • QuotesDownload: Downloads quote properties.

Because of extension posibilities the namepsaces are structured like this: MaasOne.[KindOfWebService].[NameOfWebService]. So, it's possible to use synergies between same kinds of web services but different web service providers.

Finance.YahooFinance

Every example in this section needs the following imports:

using MaasOne.Finance;
using MaasOne.Finance.YahooFinance; 

The Finance.YahooFinance namespace contains the classes for Yahoo! Finance web service. The download principle is always the same, but I will show you some examples for easier understanding.

At first we want to get some IDs. For that there are different classes. One of them is IDSearchDownload.

IDSearchDownload dl = new IDSearchDownload();
IDQuerySearchDownloadSettings settings = new IDQuerySearchDownloadSettings();
settings.Query = "dow";
settings.Markets = FinancialMarket.AllMarkets;
settings.ResultsIndex = 0;
settings.Server = YahooServer.Germany;
settings.Type = SecurityType.Any;
dl.Settings = settings;

Response<IDSearchResult> resp = dl.Download();

foreach (IDSearchData id in resp.Result.Items)
{
    string idStr = id.ID;
}

With IDQuerySearchDownloadSettings you can download maximum 20 results per request and you can set the start index if there are more than 20 results at all. With IDInstantSearchDownloadSettings you can download maximum 10 results without start index and no specifications like server, ranking or type etc.

A little bit special is the ID search by alphabetic index, because it's a combination of AlphabeticIDIndexDownload and IDSearchDownload.

//Download TopIndex (e.g. [A], [B], [1-9])
AlphabeticIDIndexDownload dl = new AlphabeticIDIndexDownload();
dl.Settings.TopIndex = null;
Response<AlphabeticIDIndexResult> resp = dl.Download();

//Download Index (e.g. [C], [Cl], [Ca(1/10)])
AlphabeticalTopIndex topIndex = (AlphabeticalTopIndex)resp.Result.Items[2];
dl.Settings.TopIndex = topIndex;
Response<AlphabeticIDIndexResult> resp2 = dl.Download();

//Download ID Search Results
AlphabeticalIndex index = resp.Result.Items[0];
IDSearchDownload dl2 = new IDSearchDownload();
Response<IDSearchResult> resp3 = dl2.Download(index);

IDSearchData[] idResults = resp3.Result.Items;

With the received IDs it's possible to use the other classes for downloading data. I already showed one example in the "Download Classes" section above. Here another example with HistQuotesDownload.

HistQuotesDownload dl = new HistQuotesDownload();
dl.Settings.IDs = new string[] { "GOOG" };
dl.Settings.FromDate = new DateTime(2010, 1, 1);
dl.Settings.ToDate = DateTime.Today;
dl.Settings.Interval = HistQuotesInterval.Weekly;

Response<HistQuotesResult> resp = dl.Download();

foreach (HistQuotesDataChain hqc in resp.Result.Chains)
{
    foreach (HistQuotesData hqd in hqc)
    {
        double close = hqd.Close;
        double closeAdj = hqd.CloseAdjusted;
        long volume = hqd.Volume;
        //...
    }
}

The other download classes in this namespace (and also most in this library) are working with the same principle: instanciate, set settings, download response, use result data.

Finance.YahooFinance.Support

Support namespace provides a lot of classes that are not directly necessary for getting the data. This namespace is just for handling with these data easier. For that, you have different data classes. The Support.YID class manages all information that are connecting to the Yahoo! Finance ID. Such an ID is constructed relatively structured. For getting data of the Apple stock, which is traded at XETRA stock exchange, you need the ID "AAPL.DE". The stock that is traded at NYSE has just the ID "AAPL". That shows that in most cases, you can deduce the stock exchange from the ID suffix (but there is more than one US American stock exchange, that has no suffix). For that issue, the YID class provides the StockExchange property for storing information like name, ID or trading time. You can prove if trading is active at a specific time in the machine's local timezone or UTC timezone. You can create a new instance of YID with an IDSearchResult. In most cases, the search result provides a known stock exchange and the YID constructor will manage the result data automatically. The Support.WorldMarket class manages all known, Yahoo! supported stock exchanges and a collection of some indices. You have a structure of continents, countries and indices to reflect the world market situation (provided by Yahoo!). A stock index will be represented by the YIndexID class that inherits from YID. Here you have the additional property DownloadComponents, which indicates if the downloader will load the data of the index itself or of the stocks of the index. Another IID class is YCurrencyID. This class represents currency relations of a base currency and a dependent currency. For that, there are the Currency properties BaseCurrency and DepCurrency. The result (QuotesDownload -> LastTradePriceOnly) you will download has the format 1 BaseCurrency : X DepCurrency.

Finance.YahooPortfolio

Every example in this section needs the following imports:

using MaasOne.Finance.YahooPortfolio;

With the library you're able to manage your online portfolio. In general you are doing this with aid of YPortfolioManager class. This class provides several methods for creating, editing and deleting portfolios, views and components. YPortfolioManager inherits from YAccountManager, which provides the base methods for managing login status.

private YAccountManager mManager = new YAccountManager();

private void LogIn()
{
    System.Net.NetworkCredential cred = new System.Net.NetworkCredential();
    cred.UserName = "username@yahoo.com";
    cred.Password = "password";
    bool isLoggeIn = mManager.LogIn(cred);
}

For downloading your portfolio overview you just need PortfolioInfoDownload class and YAccountManager.

if (mManager.IsLoggedIn)
{
    PortfolioInfoDownload dl = new PortfolioInfoDownload();
    dl.Settings.Account = mManager;
    Response<PortfolioInfoResult> resp = dl.Download();
    foreach (PortfolioInfo pfi in resp.Result.Items)
    {
        string id = pfi.ID;
        string name = pfi.Name;
    }
}

If you want to download a special view of a single portfolio you need also YAccountManager and the specific portfolio ID for PortfolioDownload settings. Real-Time and Fundamentals view are static. They can not be edited or deleted.

if (mManager.IsLoggedIn)
{
    PortfolioDownload dl = new PortfolioDownload();
    dl.Settings.Account = mManager;
    dl.Settings.PortfolioID = "your_portfolio_id";
    dl.Settings.ViewIndex = 0; //The first view
    //dl.Settings.DownloadRealTimeView = true; //Real-Time
    //dl.Settings.DownloadFundamentalsView = true; //Fundamentals

    Response<Portfolio> resp = dl.Download();

    Portfolio pf = resp.Result;

    string[] allViews = pf.AvailableViews;
    string selView = pf.SelectedView;

    foreach (IID id in pf.IDs)
    {
        string idStr = id.ID;
    }


    PortfolioColumnType[] columns = pf.Columns;
    foreach (PortfolioColumnType clm in columns)
    {
        Debug.Write(clm.ToString() + "|");
    }
    Debug.Write("\n");
    foreach (PortfolioDataRow row in pf.Rows)
    {
        foreach (PortfolioColumnType clm in row.AvailableColumns)
        {
            object cellValue = row[clm];
            Debug.Write(cellValue.ToString());
        }
        Debug.Write("\n");
    }
}

These examples were only simple downloading work. For editing your portfolio you need to upload the new data you want to change. For that you have the YPortfolioManager. This is not like the other download classes. You don't have a Settings property and you have several events for different actions.

private YPortfolioManager mPfManager = new YPortfolioManager();

After logging in you can add a new portfolio.

Response<Portfolio> createResp = mPfManager.CreatePortfolio("MyPortfolio");
Portfolio pf = createResp.Result;
Debug.WriteLine("New Portfolio: " + pf.Info.Name);

Now you could change the name.

mPfManager.EditPortfolio(pf.Info.ID, "MyPortfolio_NewName");
                
Response<Portfolio> editResp = mPfManager.DownloadPortfolio(pf.Info.ID);
pf = editResp.Result;
Debug.WriteLine("Edit Name: " + pf.Info.Name);

Or delete it again.

Response<PortfolioInfoResult> deleteResp = mPfManager.DeletePortfolio(pf.Info.ID);
PortfolioInfo[] restPortfolios = deleteResp.Result.Items;

The next step would be adding new stocks to the portfolio.

Response<Portfolio> addResp = mPfManager.AddPortfolioItem("portfolioID", "GOOG");
Portfolio pf = addResp.Result;
foreach (IID id in pf.IDs)
{
    if (id.ID == "GOOG")
    {
        Debug.WriteLine("found");
    }
}

Of course you're also able to delete them.

mPfManager.DeletePortfolioItem(pf.Info.ID, "GOOG");

In Yahoo! Portfolio you can set holdings for your stocks. At first you have to download the actual data. You can do that with HoldingsDownload/YAccountManager or YPortfolioManager.

HoldingsDownload dl = new HoldingsDownload();
dl.Settings.Account = mManager;
dl.Settings.PortfolioID = "portfolioID";
Response<HoldingsResult> resp = dl.Download();

Holding[] holdings = resp.Result.Items;

foreach (Holding h in holdings)
{
    string id = h.ID;
    int shares = h.Shares;
    double pricePaid = h.PricePaid;
    Nullable<DateTime> tradeDate = h.TradeDate;
    //...
}

Now you can edit and update the values.

holdings[0].PricePaid = 35.29;
holdings[0].Shares = 100;
holdings[0].TradeDate = DateTime.Today;

mPfManager.EditHoldings("portfolioID", holdings);

Hint: You can use EditHoldings method to add or delete multiple items/IDs of your portfolio or clear it completely (empty Array). The portfolio will be updated completely by the passed Holding-Array.

Creating, editing and deleting portfolio views is nearly the same, so I will jump now to Yahoo! Search BOSS.

Search.BOSS

Every example in this section needs the following imports:

using MaasOne.Search.BOSS;

Yahoo! Search BOSS is the latest web service for using Yahoo!'s web, image and news search (also spelling and blogs). The library is using BOSS v2. If you want to use that service you have to register and create an OAuth key and to pay for it. After getting that OAuth key you're able to use this part of Yahoo! Managed to simply automate your BOSS queries.

For that issue you have the Search.BOSS.SearchDownload class. Primarily you have the normal SearchDownloadSettings class for setting OAuth credentials etc.

SearchDownload dl = new SearchDownload();

SearchDownloadSettings settings = dl.Settings;
dl.Settings.ConsumerKey = "your_oauth_key";
dl.Settings.ConsumerSecret = "your_oauth_secret";
dl.Settings.HttpsUsed = true;

After setting universal options you have to set the service you want to use. It's possible to use multiple services in a single query.

Culture culture = new Culture(Language.en, Country.US);
string queryText = "test";

SearchService service = null;

WebSearchService web = new WebSearchService();
web.LimitedWeb = true;
service = web;
service.Culture = culture;
service.Query = queryText;
service.Index = 0;
service.Count = 10;
dl.Settings.Services.Add(service);

NewsSearchService news = new NewsSearchService();
news.AlwaysLatestDateNow = true;
service = news;
service.Culture = culture;
service.Query = queryText;
service.Index = 0;
service.Count = 10;
dl.Settings.Services.Add(service);

ImageSearchService images = new ImageSearchService();
images.Dimensions = ImageSearchDimensions.All;
service = web;
service.Culture = culture;
service.Query = queryText;
service.Index = 0;
service.Count = 10;
dl.Settings.Services.Add(service);

Then you can start downloading the data. The result is splittet into different SearchDataConatiner classes for each service type. There you have the Type property which indicates the type of service and the type of specialized container class like WebSearchDataContainer. For the Items you have the SearchData class and it's specialized service inheritors like WebSearchData.

Response<SearchResult> resp = dl.Download();

foreach (SearchDataContainer container in resp.Result.Containers)
{
    if (container.Type == SearchResultType.Web)
    {
        WebSearchDataContainer webContainer = (WebSearchDataContainer)container;
        foreach (WebSearchData wsd in webContainer.Items)
        {
            SearchData sd = wsd;
            string title = sd.Title;
            string description = sd.Description;
            Uri url = sd.Url;
            Uri clickUrl = sd.ClickUrl;

            string displyUrl = wsd.DisplayUrl;
            Language lang = wsd.Language;
            DateTime crawlDate = wsd.CrawlingDate;
        }
    }
}

Participate in the Project

I'm looking forward to extend this project to other web services. If you're also interested, you could participate in the project. The main work would be creating Settings classes (and URLs) and result parsing methods. The frame of downloading data is already available.

If you're interested just send a mail.
