> How to do for visualizing a weekly EMA (C,5) in a daily chart?
> thanks
The following code is accurate but does not give a value for the current
partially completed week. I have an adjustment that does that but it's
pointless because the value changes as each day of the week is added. Only
values for completed weeks are fixed and correct.
This formula can also be used to find the weekly Wilders Smoothing value by
changing Pct to "Pct:=1/Pds;"

{Weekly Frame EMA}
Pds:=Input("Weekly periods",1,99,5);
Pct:=2/(Pds+1);
W1:=DayOfWeek()=5; W2:=Alert(W1,2);
W3:=DayOfWeek()<=Ref(DayOfWeek(),-1);
We:=If(W1,1,If(W2=0 AND W3,2,0));
Wcl:=ValueWhen(1,We>0,If(We=1,C,Ref(C,-1)));
Ema:=If(We>0,If(Cum(We>0)=1,C,PREV)*(1-Pct)+ Wcl*Pct,PREV);
Ema;
