How does one get the history data of a stock
EpEthan opened this issue · comments
I'm sorry if this is a redundant or stupid question. However, I copied the code given in the README.md
file for getting historical data for a stock, yet the program did not display any data - rather, it simply terminated after the function Yahoo.GetHistoricalAsync()
.
Sorry again if this is a stupid question. I'm only a beginner and still trying to get the hang of coding...
This is the code by the way:
var history = await Yahoo.GetHistoricalAsync("AAPL", new DateTime(2016, 1, 1),
new DateTime(2016, 7, 1), Period.Daily);
foreach (var candle in history)
{
Console.WriteLine($"DateTime: {candle.DateTime}, Open: {candle.Open}, High: {candle.High},
Low: {candle.Low}, Close: {candle.Close}, Volume: {candle.Volume},
AdjustedClose: {candle.AdjustedClose}");
}
Actually, no exception is thrown. That's what is weird: the program terminates without writing anything. Do you have any idea why it's happening?
Where can I find it?
Again, sorry if these are all dumb questions...
Hello everybody,
I have tested exactly the same code as EpEthan, in C# or vb.net but I always have this exception :
"Exception : Could not convert '2016-01-04,25.652500,26.342501,25.500000,26.337500,24.323219,270597600' to DateTime."
Do you know why ?
Thank you
Hello everybody,
Nobody have an idea about my problem ?
At the beginning I have :
`Option Strict On
Imports YahooFinanceApi
Imports System.IO
Imports System.Threading.Tasks
Imports System.Collections.Generic
Imports System`
And my sub is ;
`Private Async Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim dateDebut, dateFin As String
dateDebut = "2021/01/01"
dateFin = "2021/04/01"
Dim dd As Date = DateTime.Parse(dateDebut)
Dim df As Date = DateTime.Parse(dateFin)
Dim prices As New List(Of String)
Dim history = Await Yahoo.GetHistoricalAsync("AIR.PA", dd, df, Period.Daily)
For Each candle In history
prices.Add(candle.High.ToString)
Label1.Text = candle.High.ToString
Console.WriteLine($"DateTime: {candle.DateTime}, Open: {candle.Open}, High: {candle.High}, Low: {candle.Low}, Close: {candle.Close}, Volume: {candle.Volume}, AdjustedClose: {candle.AdjustedClose}")
Next
End Sub`
I tried to read a value of historical in a List, in a Label, in the console but nothing wrong...
What am I doing wrong ?
I have no problem with ohter Yahoo functions like
'Dim securities = Await Yahoo. 'Symbols(txtTickers.Text.Split(","c)). 'Fields(Field.Symbol, Field.RegularMarketPrice, Field.RegularMarketTime, Field.Currency, Field.LongName, Field.RegularMarketDayHigh, Field.RegularMarketDayLow, Field.RegularMarketVolume). 'QueryAsync()
I suggest you try: https://github.com/dshe/YahooQuotesApi
ok thank you I will have a look but I would have preferred to understand my mistakes
Problem solved after uninstall and install again all packages!
