Bill,
DateTime(0 is encoded date/time in special format that allows display
both date and time according to your system settings.
It has nothing to do with bar index.
To get the period use
Period = EndValue( BarIndex() ) - BeginValue( BarIndex() );
Second question:
Use C-like \n escape sequence (backslash and small n)
Title = "First line\nSecond line";
Best regards,
Tomasz Janeczko
