I have been using this spreadsheet and it has been great! However, I have come upon an issue when running daily close data for S&P 500 (^GSPC) with a start date of 11/1/2010 to 11/25/2010 (I have tried various dates in this range) with an end date of today, 12/7/2011. I have noticed that a beginning chunk of data from Nov 2010 is missing. The dates show but the close data does not appear. I do not receive any errors, the data just does not appear. I have been trying to figure this out with no luck. Can anyone help? Has anyone else ran into a similar issue? I tried deleting temporary internet files and this has not helped...
