Draw region between 2 indicator lines

[sandman]

Hi. I would appreciate some guidance to get the following accomplished:

I have an indicator that colors the region between the EMA and LinReg but it does it based on whether the LinReg is faster than the EMA. See attached Image 1.

What I'd like to change is that the region between the two lines is colored depending on whether the LinReg is falling or rising as depicted in the attached photoshopped Image 2.

Can the existing code be modified to accomplish that (I can post that code if needed) or would it be better to start from scratch?

Where do I start keeping in mind that my coding capabilities are minimal.

Hi Sandman,

Thank you for posting.

Yes, the existing code can be modified. For the rising and falling you can use the function check Rising and Falling with in the if statement that draws the region.

Example -

if(Rising(LinReg(20)))
{
     DrawRegion(...);
}

Let me know if I can be of further assistance.

You can find the indicator here:

It is a free download for elite members.

Below is the code section used to do the coloring. It is more complex than usual in order to allow to shift the indicator plot forwards and backwards.

            {
                PlotColors[0][-Displacement] = upColor;
                PlotColors[1][-Displacement] = upColor;
                if(opacity != 0)
                {    
                    if(FirstTickOfBar)
                        priorIndex = index;
                    count = CurrentBar - priorIndex + 1 - Displacement;
                    if(upTrend[1])
                    {
                        if(index == CurrentBar)
