Recursive Moving Trend Average.

["VonHef"]

List,
If all you want is the code......here is my version of it:

 {Recursive Moving Trend Average}
Lb:=Input("Look-Back Period?",3,100,21);
Ty:=Input("1=C 2=H 3=L 4= Median Price",1,4,1);
Tv:=If(Ty=1,C,If(Ty=2,H,If(Ty=3,L,MP())));
Alpha:=2/(LB+1);
Bot:=(1-Alpha)*(If(Cum(1)<Lb,Tv,PREV))+Tv;
RMTA:=(1-Alpha)*(If(Cum(1)<Lb,Tv,PREV))+
     (Alpha*(Tv+Bot-Ref(Bot,-1)));
RMTA

  Best wishes,
      Adam Hefner.
