VBA code leads to value in cell but works in immediate box

0 votes

I have written a getprice function for retrieving stock tickers from yahoo and bitcoin prices from an online api. However the code for bitcoin results in an #value! in my excel cell. But it performs fine when I run the function from the immediate box in VB.

This is my code: 

Function GetPrice(strTicker As String, Optional dtDate As Variant)

  Debug.Print "Getting Price..."

  ' Date is optional - if omitted, use today. If value is not a date, throw error.
  If IsMissing(dtDate) Then
    dtDate = Date
  Else
  If Not (IsDate(dtDate)) Then
    GetPrice = CVErr(xlErrNum)
    Debug.Print "Date problem!"
  End If
  End If

  ' Define variables
  Dim dtPrevDate As Date
  Dim strURL As String, strCSV As String, strDate As String, strRows() As String,       strColumns() As String
  Dim priceArray() As Variant
  Dim wb As Workbook
  Dim dbClose As Double
  dbClose = 1 ' default for if price not found

  ' for stock tickers look at a weeks worth of data in case date is weekend
  dtPrevDate = dtDate - 7

  ' Treat bitcoin separately and compile CSV with all BTC data
  If strTicker = "BTCUSD" Then
     ' go to the URL
     strURL = "https://api.bitcoinaverage.com/history/USD/per_day_all_time_history.csv"
     priceArray = CsvToArray(strURL) 'convert to array

     ' Bitcoin date search
     strDate = CStr(dtDate)
     Debug.Print "Date: "; strDate

     ' side question but i dont understand why this vloopkup doesnt work???
     'dbClose = Application.VLookup(DateValue(strDate), priceArray, 4, False) ' lookup  value in column d
     'try parsing array manually instead
      For i = LBound(priceArray) To UBound(priceArray)
         If CStr(priceArray(i, 1)) = strDate Then
             dbClose = CDbl(priceArray(i, 4))
             Exit For
         Else
            dbClose = 1
        End If
      Next i


 ' For all other tickers
 ' Compile the request URL with start date and end date
 Else
    Debug.Print "stock ticker:"; strTicker
    strURL = "http://ichart.yahoo.com/table.csv?s=" & strTicker & _
    "&a=" & Month(dtPrevDate) - 1 & _
    "&b=" & Day(dtPrevDate) & _
    "&c=" & Year(dtPrevDate) & _
    "&d=" & Month(dtDate) - 1 & _
    "&e=" & Day(dtDate) & _
    "&f=" & Year(dtDate) & _
    "&g=d&ignore=.csv"

    ' Declare an object as the http data
    Set http = CreateObject("MSXML2.XMLHTTP")
    http.Open "GET", strURL, False
    http.Send
    strCSV = http.responseText

    ' The most recent information is in row 2, just below the table headings.
    ' The price close is the 5th entry
    strRows() = Split(strCSV, Chr(10)) ' split the CSV into rows
    strColumns = Split(strRows(1), ",") ' split the relevant row into columns. 1 means 2nd row, starting at index 0
    dbClose = strColumns(4) ' 4 means: 5th position, starting at index 0

 End If

 If dbClose = 1 Then
    GetPrice = "Not Found"
    Debug.Print "GetPrice"; GetPrice
 Else
    GetPrice = dbClose
    Debug.Print "Price: "; GetPrice
 End If

 Set http = Nothing

End Function

Function CsvToArray(filepath As String) As Variant
  Dim wb As Workbook
  Dim array1() As Variant

  Application.ScreenUpdating = False
  Set wb = Workbooks.Open(filepath)

  ' THIS LINE SEEMS TO CAUSE THE PROBLEM
  array1 = wb.Sheets(1).Range("A1").CurrentRegion.Value
  wb.Close False

  CsvToArray = array1
  Application.ScreenUpdating = True
End Function

I don't think you can access the bitcoin url the way that you're trying to do so. Excel can't actually trigger the file download & and the file path that you're trying to use for the CsvToArray method doesn't make sense.

try something like this:

Function GetPrice(strTicker As String, Optional dtDate As Variant)

Debug.Print "Getting Price..."

' Date is optional - if omitted, use today. If value is not a date, throw error.
If IsMissing(dtDate) Then
   dtDate = Date
Else
   If Not (IsDate(dtDate)) Then
      GetPrice = CVErr(xlErrNum)
      Debug.Print "Date problem!"
   End If
End If

' Define variables
Dim dtPrevDate As Date
Dim strURL As String, strCSV As String, strDate As String, strRows() As String, strColumns() As String
Dim priceArray() As Variant
Dim wb As Workbook
Dim dbClose As Double
Dim desiredRow, desiredCol as Long
dbClose = 1 ' default for if price not found

' for stock tickers look at a weeks worth of data in case date is weekend
dtPrevDate = dtDate - 7

' Treat bitcoin separately and compile CSV with all BTC data
If strTicker = "BTCUSD" Then
 ' go to the URL
    strURL = "https://api.bitcoinaverage.com/history/USD/per_day_all_time_history.csv"

' For all other tickers
' Compile the request URL with start date and end date
Else
    Debug.Print "stock ticker:"; strTicker
    strURL = "http://ichart.yahoo.com/table.csv?s=" & strTicker & _
    "&a=" & Month(dtPrevDate) - 1 & _
    "&b=" & Day(dtPrevDate) & _
    "&c=" & Year(dtPrevDate) & _
    "&d=" & Month(dtDate) - 1 & _
    "&e=" & Day(dtDate) & _
    "&f=" & Year(dtDate) & _
    "&g=d&ignore=.csv"
End If

' Declare an object as the http data
Set http = CreateObject("MSXML2.XMLHTTP")
http.Open "GET", strURL, False
http.Send
strCSV = http.responseText

' The most recent information is in row 2, just below the table headings.
' The price close is the 5th entry
strRows() = Split(strCSV, Chr(10)) ' split the CSV into rows

If strTicker = "BTCUSD" Then
    'ADD LOGIC HERE TO FIND DESIRED DATE

    desiredRow = UBound(strRows)
    desiredCol = 2
Else
    desiredRow = 2
    desiredCol = 5
End If

strColumns = Split(strRows(desiredRow - 1), ",") ' split the relevant row into columns. 1 means 2nd row, starting at index 0
dbClose = strColumns(desiredCol - 1) ' 4 means: 5th position, starting at index 0


If dbClose = 1 Then
   GetPrice = "Not Found"
   Debug.Print "GetPrice"; GetPrice
Else
   GetPrice = dbClose
   Debug.Print "Price: "; GetPrice
End If

Set http = Nothing

End Function
