Are you sure you do not want this:

 

output2[ i ] = f * Close[ i ] + (<font
size=2 face=Verdana>1 - f) *
output2[ i - 1<span
> ]; // you had <font size=2
face=Verdana>output2[ <span
class=SpellE>i &#8211; <i
>2]<font size=2 color=navy
face=Arial>

 

You are multiplying times a bar 2 days ago
in the current formula.

 

Regards,

Peter

I noticed some strange effect moving the graphs one bar forward.





The red curve is not the same, especially on the left side of the
graph.





Do we have here an undesirable resonance effect ?





How could I avoid this ?

I used the following code to compare EMA with its "Echo"





 





n=20;<font
size=2 face=Verdana>





output1[ <span
>0 ] = Close[ 0 ];output1[ 1 ] = Close[
1 ];<font
size=2 face=Verdana>





output2[ <span
>0 ] = Close[ 0 ];output2[ 1 ] = Close[
1 ];<font
size=2 face=Verdana>





f = 2/(n+1<span
>);<span
>





for( i = 2; i < BarCount; i++ )<span
>





{





output1[ i ] = f * Close[
i ] + (1 - f) * output1[ i - 1<span
> ];<span
>





output2[ i ] = f * Close[
i ] + (1 - f) * output2[ i - 2<span
> ];<span
>





}





Plot(Output1,"EMA",1,1<font
size=2>);<font size=2
face=Verdana>





<span
>Plot<font size=2
face=Verdana>(Output2,"ECHO
EMA",4,1);<font
size=2 face=Verdana>
