BoolSeries

Hey guys,

What am I doing wrong here?

    public class Black : Indicator
    {
        #region Variables

        {
            Overlay	= false;
			NR4 = new BoolSeries(this, MaximumBarsLookBack.Infinite);
        }

        
        protected override void OnBarUpdate()
        {
				
			if(Bars.GetDayBar(4).Close != null)
			{
			R1 = Bars.GetDayBar(1).High - Bars.GetDayBar(1).Low;
			R2 = Bars.GetDayBar(2).High - Bars.GetDayBar(2).Low;
			R3 = Bars.GetDayBar(3).High - Bars.GetDayBar(3).Low;
			R4 = Bars.GetDayBar(4).High - Bars.GetDayBar(4).Low;
			}
			else return;
			
			NR4.Set(R1 < R2 && R1 < R3 && R1 < R4 ? true : false);
        }

        #region Properties

        #endregion
    }
}

I am getting a error:

Error on calling 'OnBarUpdate' method for indicator 'Black' on bar 0: Object reference not set to an instance of an object.

Any help would be appreciated.

Hi SodyTexas,

On the check you're making here:
if(Bars.GetDayBar(4).Close != null)

You would want instead:
if(Bars.GetDayBar(4) != null)

Awesome, thanks I was stumped on that!
