The data disapearing act has been solved. The other issues is still a mystery to me.
Is "Number of bars" defined in "File -> Database Settings" high enough to hold all the bars? Note that if you exceed that value, then the oldest bars get removed to maintain the requested database size. So - that would mean the oldest (EOD) quotes get wiped-out first. Please increase "Number of bars" in File -> Database Settings, then check if you're getting the same problem.
