Thanks for you help.

I have created version 1 of what I had in mind, based largely on the approach you posted.

Here it is, and while it is not quite what I am looking for, I seem to be "in the area".

And it does not involve loops. How about that!!!

K = Param("% Coeff of Correlation",5,1,50,1);

Period = Param("Lookback Period",5,1,20,1);

Hi = HHV(C,Period );

Lo = LLV(C,Period );

HTrend = Hi * (1-(K/100));

LTrend = Lo * (1+(K/100));

UpTrend = Cross(Ltrend,C);

DnTrend = Cross(C,HTrend);

Trend = Flip(UpTrend,DnTrend);

Trendindicator = IIf(Trend ==1,HTrend,LTrend);

Trendcolor = IIf(Trend ==1,colorRed,colorWhite);

Plot(C,"",colorYellow,64);

Plot(Trendindicator ,"HTrend",Trendcolor ,1);

Rick,

I hope it helps you with your AFL.
I find with learning anything that sometimes we reach a sticking
point or it seems overwhelming but if we remain immersed in the
subject imperceptibly things that seemed difficult start to become
easy and we don't actually notice when exactly that learning happened.

I documented my 'messiness' so that you could see how I go about a
basic AFL project - starting at the top, working sequentially,
working in steps or modules, plotting everything to see if it works
and what it looks like (also using the Explorer to report that
outcomes of my code. I also use my calculator and do a lot of manual
cross checking of calculations e.g. I start at the beginning of the
chart and follow multiple plots to see what my code is actually doing.

I don't know if I qualify as a programmer - I'm more of a 'paint by
numbers' man.

BTW - after I posted I noticed that you did ask for HHV(Close, P) and
I used the H and the L - you should be able to adjust it to get what
you want.

Struggling to learn is good. Frustrated with learning is not so good
(I think we all get frustrated with AB/programming at some stage).

Cheers,

Brian_z.
