Accessing the value of a slope indicator

[pandyav]

Hello,
I am trying to plot the slope of HoltEMA. I already have the slope and HoltEMA indicators. Both the indicators are attached.

I want to achieve the following by either writing a brand new indicator or by adding a code snippet in existing Slope indicator.

- Whenever the value of HoltEMA's slope is more than 5 bar color turns yellow and if less than -5, bar color turns blue

I added the following code the existing slope indicator, but I am not able to accomplish what I want.

if (PlotUp[0] >=5)
{
BarColor = Color.Yellow;
}
if (PlotDn[0] <=-5)
{
BarColor = Color.Blue;
}

Can someone please help me with what am I doing wrong here.
Very much appreciate your help in advance.

pandyav, where exactly did you add that logic to color into the slope script? Testing the same setup I don't see any issue here, would perhaps help as well to mark up your levels on the slope via horizontal lines to see when the conditions should trigger for you.
