Roy,
Thanks! So far the formula that I have come up with doesn't quite get
it... but its close. The problem, I think, is with the slope
calculation. Should be easy enough to subtract the value of the slope
from the oldest high and plot forward but so far its eluding me. I
know that I could use an if statement but I was hoping for a variable
input.

{BarBack DescendView}
len:=Input("Periods for Ref High",1,100,20);
Signal:=Ref(H,-len);
Barbk:=Input("Barsback High",1,100,8);
Signal2:=Ref(H,-Barbk);
{Periods:=len;} {periods to display last value}
{Line Plot }
D1:=Cum(1)=LastValue(Cum(1))-LastValue(len);
{D1 is first bar of line}
D2:=Cum(1)=LastValue(Cum(1))-LastValue(len)-(barbk);
{D2 is last bar of line}
P1:=signal2; {start-of-line data array}
P2:=signal; {end-of-line data array}
V1:=ValueWhen(1,D1,P1);
V2:=ValueWhen(1,D2,P2);
B1:=LastValue(BarsSince(D1));
B2:=LastValue(BarsSince(D2));
Line:=V1-Cum(If(D1=0,(v1/v2)-(b1/b2),0));
Line:=Ref(Ref(line,-barbk),barbk); {blank end of line}
Line;
aLine:=v1-Cum(If(D1=0,(b1*v1)/(b2*v2),0));
aLine:=Ref(Ref(aline,-barbk),barbk); {blank end of line}
aLine;
