Hello,
This is a feature that is switchable by the user.
In Automatic Analysis, SETTINGS window there is a
"Pad and align all data to reference symbol"
that controls that.
If the checkbox is OFF then the behaviour is as you described.
If the checkbox is ON then all data are padded to reference symbol
and if there is hole it gets padded with previous day data.
You should take attention to choose the symbol without any holes
(such as index) as your reference symbol.
Best regards,
Tomasz Janeczko
