Have you evern seen an indicator like this one?

Ran across this indicator on some random website: http://trader.online.pl/MSZ/e-w-Movi...ist_Suppt.html

I've also seen an indicator similar to this one in Kwikpop. Does anyone know of a way to create something similar with efs?
Here is the code that the creator used to build it in metastock:

Resistance and Support

LookBack := Input("Look Back Periods",1,1000,10);
Resistance :=ValueWhen(1,Cross(Mov(C, LookBack,S),C),HHV(H, LookBack));
Support :=ValueWhen(1,Cross(C,Mov(C, LookBack,S)),LLV(L, LookBack));
Resistance;
Support;





_




Resistance and Support * F

PrCnt:=Input("Percentage",0,100,10);
LookBack:= Input("Look Back Periods",1,1000,10);
Resistance:=ValueWhen(1,Cross(Mov(C,LookBack,S),C) ,HHV(H,LookBack));
Support:=ValueWhen(1,Cross(C,Mov(C,LookBack,S)),LL V(L,LookBack));
Resistance * ((100-prcnt)/100);
Support * ((prcnt/100)+1);
