Would it be possible to get the name of the historicprice??

Im trying to get it 2 or 3 symbols in one .csv file

Hi ZacMarcus,

I noticed the values returned from this package are far too big (usually x10000 of the correct value).

The reason for this is quite simple: Yahoo, of course, delivers its values in US format. My default thread culture however is German. I took a look in the source code and noticed you're using the default parse methods like decimal.Parse(values[1]) without specifying the culture explicitly.

So the problem would be solved by specifying the US format explicitly to the parse methods.

Thanks a lot,
Zacko

Hi ZacMarcus,

I have tried YahooFinance API, YahooFinance.GetDailyHistoricalPriceData is working to get the historical data.

However, when I call the YahooFinance.GetRealTimeData(yahoostockcode), there is WebException: The remote name could not be resolved: 'download.finance.yahoo.com'

I also tried Dim listdividendhistory As Object = YahooFinance.GetHistoricalDividendData(yahoostockcode), but no record count returns .

Here is my coding, do I need to handle the cookie and crumb ?

    Dim cookie As String = "YOUR_COOKIE"
    Dim crumb As String = "YOUR_CRUMB"

    Dim exchange As String = "HKG"
    Dim symbol As String = "0001"

    Dim YahooFinance As New YahooFinance.NET.YahooFinanceClient(cookie, crumb)  'retrieve cookies
    Dim yahoostockcode = YahooFinance.GetYahooStockCode(exchange, symbol)

Dim listhistoricalprice As Object = YahooFinance.GetDailyHistoricalPriceData(yahoostockcode)
Console.WriteLine("Historical Price")
For Each histprice In listhistoricalprice
With histprice
Console.WriteLine("Date: " & .Date & " Open: " & .Open & " High: " & .High & " Low: " & .Low & " Close: " & .Close & " AdjClose: " & .AdjClose & " Volume: " & .Volume)
End With
Next

    Dim listrealtimeprice As Object = YahooFinance.GetRealTimeData(yahoostockcode)
    Console.WriteLine("Real Time Price")
    For Each realtimeprice In listrealtimeprice

        With realtimeprice
            Console.WriteLine("Ask: " & .Ask & " Bid: " & .Bid & " Last: " & .Last & " PreviousClose: " & .PreviousClose _
                & " Open: " & .Open & " High: " & .High & " Low: " & .Low & " LastTradeTime: " & .LastTradeTime & " Volume: " & .Volume _
                & "Symbol: " & .Symbol & " Name: " & .Name)

        End With
    Next

Thanks
Davy

Hello,

The following method do not return correct values except for US, UK & australian market (ok, the most important ones ;) )

public string GetYahooStockCode(string exchange, string code)
        {
            switch (exchange)
            {
                case "ASX":
                    return $"{code}.AX";
                default:
                    return code;
            }
        }

The complete list of suffix is available on http://finance.yahoo.com/exchanges

Maybe an enum of MarketExchange can make the use of the API easier ?

Any ideas

Hi Team,

Love your work!! everything is working great except i cannot get the historical date for a given start date and end date, does this still work for you?

        Dim exchange As String = "ASX"
        Dim symbol As String = "ABC"
        Dim yahooFinance As YahooFinanceClient = New YahooFinanceClient(cookie, crumb)
        Dim yahooStockCode As String = yahooFinance.GetYahooStockCode(exchange, symbol)
        Dim yahooPriceHistory As List(Of YahooHistoricalPriceData) = yahooFinance.GetDailyHistoricalPriceData(yahooStockCode, New DateTime(2017, 12, 5), New DateTime(2017, 12, 8))

Yahoo changed url couple of days ago, so connection with a server cannot be established. New url starts with https://query1.finance.yahoo.com/v7/finance/download...
