V simple but I am not getting it!

[Mindset]

if(Bars.GetDayBar(1) != null)
Print("The prior trading day's High is: " + Bars.GetDayBar(1).High);//Add your custom indicator logic here.
myline = Draw.HorizontalLine(this,"tag",Bars.GetDayBar(1).C lose,Brushes.Chartreuse);

Why do I get an object reference error here?
I set the object I thought using this
private DrawingTools.HorizontalLine myline;

thanks

Hello Mindset,

This is likely because you are not using curly braces to contain your conditions code. An if statement like you have it will execute 1 line following it. You have 2 lines so only the first sees the variable in the if condition.

if(Bars.GetDayBar(1) != null)
{
   Print("The prior trading day's High is: " + Bars.GetDayBar(1).High);//Add your custom indicator logic here.
   myline = Draw.HorizontalLine(this,"tag",Bars.GetDayBar(1).C lose,Brushes.Chartreuse);
}
