Leo:
What program are you using to obtain Yahoo data?
Some programs automatically obtain delayed (Reuters), rather than historical
(CSI), data and then overwrite the delayed when the historical is
available. It sounds like your program automatically fills in the current
date with the last available historical data, which could be confusing.
Have you looked at the raw data to see what the program is
doing?

Hi,When using the explorer to rank securities according
to a specific RSI value, I'discovered' something strange.Say
you're screening for an oversold condition on the most recent date (or
aspecific date if you want to do somebacktesting) and one of your
securities lacks to most recent data (or somehistorical value if you're
backtesting)it still shows up in the report and can be even your best
candidate !! For thissecurity the yesterday's value isused!Is
this normal ? Known ?I use Yahoo (CSI) for data
retrieval.
