hey jason.... it helps to have any historical intraday securites in the same folder.... make sure you have created a security in your local data folder .... as an example the path should be ' C:\\MetaStock Data\\intraday\\csco ' where intraday is the subfolder in metastock local data main folder and csco is csco.....
to update those securities check the option saying enable realtime updates when you initially created the securities/folder.... .... make sure the folder is listed in your configuration..... click tools-> options -> realtime -> configure server -> file updates.... if your folder is not listed, click add and type in the path..... most often meta will notice that the folder contains intraday charts and is not set for realtime updates.... it will ask if you would like to add it....
of course, it will only auto update if your online..... like g said, any missing data stays missing unless you manually add it.... and like patrick said long ago, go lite of realtime securities, it really eats up bandwith......h
