I noticed that when I tried a data update for March 28 some of the closing data in excel was not consistent with what was in Yahoo historical data. It was not the current date but back to December 2013 that seemed inconsistent with what Yahoo historical data was and the numbers that showed up in Excel for a given date. For example, for December 31, 2013 using daily data Yahoo Finance displays a value for IWM of 115.06 and Excel comes back with a value of 110.80 for December 31, 2013.Apologies if this issue has been addressed in the past. Never had this problem before.

I'm not seeing what you're describing. What parameters were you using with
RCHGetYahooHistory()?
There have been some notices of issues with history from Yahoo, but they've
been of missing data. For example, IWM right now skips from Jan 9th to Jan
27th of 2014.
I've also had a few issues with no historical data being found, using the
browser. But a simple refresh of the browser fixes the issue. So likely
another Yahoo glitch?
