Where do i place some variables ?

OnStartup() is called before OnBarUpdate() so you do not have access to bar objects there.

If you're trying to access indicator or bar values, will need to access in OnBarUpdate().

RyanM,
mm.... seems doesn't work:

protected override void OnStartUp()
{
sess_Open = CurrentDayOHL().CurrentOpen[0];
}

sess_Open as a variable(double) under Variables.

Hi mate41,

Best practice here is to declare all variables in the Variables region.

For actions you want to take only once before OnBarUpdate(), there is dedicated handler OnStartup()

Hello,
when some variables are only to be initiated once; before the "on bar update"; where are they to be set ?
And is this true for all types of variables ?
