Ways to make a live spreadsheet

what are the options to get live data into the spreadsheet to update market tickers regularly. I wrote some Basic Timer but to get this API working I dunno what options I have, could some pro’s enlighten me?

I like opensource, people made it already in google docs: Cryptocurrencies - Google Tabellen which i oppose.

I am here, but lost: http://api.libreoffice.org/examples/examples.html If possible i would stick with libreoffic basic, otherwise we need glue code.
So far I found: http://api.libreoffice.org/examples/basic/stock_quotes_updater/

Function GetValue( oDocument As Object,_
                   sName As String,_
                   fDate As Double, fValue As Double )
	Dim sUrl As String, sFilter As String
	Dim sOptions As String
	Dim oSheets As Object, oSheet As Object

	oSheets = oDocument.Sheets
	If oSheets.hasByName("Link") Then 
		oSheet = oSheets.getByName("Link")
		oSheet = _
		oSheets.insertByName("Link", oSheet)
		oSheet.IsVisible = False
	End If

	sUrl = "http://quote.yahoo.com/d/quotes.csv?s=" +_
	 sName + "&f=sl1d1t1c1ohgv&e=.csv"
	sFilter = "Text - txt - csv (StarCalc)"
	sOptions = _
	oSheet.LinkMode = com.sun.star.sheet.SheetLinkMode.NONE
	oSheet.link(sUrl, "", sFilter, sOptions, 1 )

	fDate = oSheet.getCellByPosition(2,0).Value
	fValue = oSheet.getCellByPosition(1,0).Value
	GetValue = (fDate <> 0)
End Function

Hello @creativeflowers,

Please have a look at these two LibreOffice extensions:

LibreWeb - allows to fill the spreadsheet cells with data from different web pages.

SMF Extension for LibreOffice Calc - allows you to create customized spreadsheets with stock market data directly from the web.
