GetQuotes-Yahoo Script doesnt seem to be working/Power BI doesnt seem to be updating intraday

edited January 11 in External Data Files
My Power BI used to update multiple times as per my schedule refresh but now i have to manually refresh it. Any thoughts?


In my log under GetQuotes-Yahoo.txt file i am getting the below message for all of my symbols:

Symbol: SQD.V. Next date: 2022-01-11. Quote file: C:\PortfolioSlicer\Data\Quotes\_SQD.V_.txt
Requesting url:
SQD.V - Not Found (web err)

Any ideas?

Below is the script that i am using:

$logSummary = (Get-Date).ToString("HH:mm:ss") + " Script: Yahoo Historical".PadRight(28);

  • My understanding PowerBI attempts to do refresh 3 to 5 times and if fails, then disables automatic refresh. To re-enable automatic refresh you have to go back to the Dataset, select "Schedule Refresh" and then click toggle under "Keep your data up to date".

    Regarding quotes not updating:

    It takes usually at least till 9pm ET for normal day quotes to be available for download with GetQuotes-Yahoo scripts. Because of such delay, there is also a script GetQuotes-YahooIntraday that could get current-day quotes sooner. Please check if GetQuotes-YahooIntraday run, and you update that script with known Yahoo adjustment as per this forum thread:

  • Thanks Vidas.

    My Schedule refresh was on but now it is failing for the following reason. I think i broke it :(

    Last refresh failed: Wed Jan 12 2022 09:11:15 GMT-0700 (Mountain Standard Time)
    There was an error when processing the data in the dataset.Hide details
    Data source error: {"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"The column 'Symbol' of the table wasn't found."}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"Expression.Error"}}],"exceptionCulprit":1}}} Table: Quotes.

    With regards to the Yahoo Intraday, it is only updating once run the UpdatePSDataIntraday.Bat. The Yahoo historical is not updating. I am getting those error messages in the log:
    Requesting url:
    ALA.TO - Not Found (web err)
  • I had recently downloaded the scripts that were on the download page which then caused all of these issues (expect for the auto refresh issue). I went back and used my back up of the old scripts i was using and now seems to work. Not sure what happened here.
