Question

Problem with Excel Web Querys of Yahoo Finance Stock Data

Asked by: mjpalma

I am trying to automatically grab various stock data from Yahoo finance.  I wrote a macro for each page I want to grab data from, for example:

http://finance.yahoo.com/q/ks?s=IT or http://finance.yahoo.com/q/is?s=IT&annual

The macros first clear out the target worksheet, including the query from a previous run of the macro and then designates that the data is to be returned to cell A1, and in fact it selects A1 before going onto creating the web query for the current iteration.    At the end of this message is an example of the macro for the first sample page listed above

There are about 10 web pages I am trying to get data from, and their is a macro for each page, and I wrote one macro to run each of these 10 individual macros.  (I am concerned that the ubber macro is going onto a new page before the previous query is completed and this may add some headaches and would like your imput on this)

Anyways, some tables are grabed and placed in their worksheets as designed every time.  But in other worksheets, such as the pages listed above and in the macro example included, the performance is much more mixed.  In some cases they work fine, but other times some combination of 1) the data is returned to the wrong location within the worksheet 2) the wrong table or Item from the page is returned 3) no data is returned 4) only part of the desired table is returned.

When I went into the edit query function, sometimes the correct tables are marked for importation, some times they are not.  There does not seem a pattern.  I dont understand why this is happening, I recored each of these macros and they worked fine before I save the macro, so it should be returning the same data, the same way each time, but this is not happening.

I searched the MS KB and they mentioned that Dynamically Scripted Tables may be interfering with the query, if this is the case is there a solution to this problem?

Would it be better to right a macro/query for each individual table I want to grab?  Though there are problems with macros/queries associated with pages where I am only going after a single table on that particular page.

The key is to retrieve the right data reliably to the correct location, any help would be greatly apprecciated.

Example Macro-
Sub keystats()

' keystats Macro
' Macro recorded 10/18/2004 by Michael J. Palma

'Setup worksheet

    Sheets("keystats").Select
        Cells.Select

'    Selection.Delete Shift:=xlToLeft
'    Range("A1").Select
'    Selection.EntireColumn.Insert
'    Selection.EntireColumn.Insert
    Range("A1").Select

'
    With ActiveSheet.QueryTables.Add(Connection:= _
        "URL;http://finance.yahoo.com/q/ks?s=IT", Destination:=Range("A1"))

        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .WebSelectionType = xlSpecifiedTables
        .WebFormatting = xlWebFormattingNone
        .WebTables = "26,31,34,37,40,43,46,53,56,59"
        .WebPreFormattedTextToColumns = True

mjpalma,

How are you determining which tables to include?  Try changing:

        .WebTables = "26,31,34,37,40,43,46,53,56,59"
to:

        .WebTables = "yfncsumtab"

for all of these queries.  You'll still have some problems with row heights but the data should end up in the same place every time.

Jim

Thanks for the quick response,

Your suggestion did return the data, but I am still getting some problems in returning the data to the same location every time, seems to be off by one row or column.  Any suggestions?

 

by: mjpalmaPosted on 2004-11-03 at 23:22:45ID: 12490809

What seems to be moving the results up or down a few rows is the presence of an advertisement on the web page that appears randomly.  Again, any help answering the problem.

mjpalma,

So, the table itself is in the same location but the contents of the table change in column H.  There's not much we can do about that since it is Yahoo's content.  Ideally, you would probably want to capture the info from the returned query into a table of your own by scanning the query results looking for specific markers (like header info: FINANCIAL HIGHLIGHTS, TRADING INFORMATION, etc.) and moving only the data you were interested in into your new table.

I think your right, and since the problem is that the data changes rows, I can pick up most of what I need by an index/match function to grab what I need.  Thanks for your help

mjpalma,

Great idea!  Thanks for the grade!

Jim,

How did you discover the table name instead of the table number?

+++++++
  From above:

        .WebTables = "26,31,34,37,40,43,46,53,56,59"
to:

        .WebTables = "yfncsumtab"

++++++

I'm doing a similar query,

With ActiveSheet.QueryTables.Add(Connection:=strURL, _
        Destination:=Cells(ColDown, 1))
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .BackgroundQuery = True
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .WebSelectionType = xlAllTables
        .WebFormatting = xlWebFormattingNone
        .WebTables = "23"
        .WebPreFormattedTextToColumns = True
        .WebConsecutiveDelimitersAsOne = True
        .WebSingleBlockTextImport = False
        .WebDisableDateRecognition = False
        .WebDisableRedirections = False
        .Refresh BackgroundQuery:=False
    End With
   
and it's in a loop which loops about 200 times.  In about 50 of those cases, it brings in a different table.  If I do the loop just once on one of those cases (that returned the wrong table in the loop) it returns the correct data.  It seems to get confused with the repetition!  I was hoping changing to the table name would help.  

Thanks,
Loy Miller

Hi, jeverist ,

I know it's an old post. But still the same problem with my code.
Can you give me some ideal, how could you come up with the table name: .WebTables = "yfncsumtab" instead of 26,31.....

Many thanks!

Sam
