Request: Ehlers Deycler (from TradingView)

  Hello,

  I’m trying to convert this Ehlers Deycler indicator from TradingView but I can’t seem to get it work.

  Here is my code:

  // Input parameters length = 60 src = close // Constants once PI = 3.141592653589793 // Variables PIx2Length = 2 * PI / length cosValue = cos(PIx2Length) alpha = 0 If (cosValue <> 0) then alpha = (cosValue + sin(PIx2Length) - 1) / cosValue else If (barindex > 1) then alpha = alpha[1] endif endif decycler = alpha / 2 * (src + src[1]) + (1 - alpha) * decycler[1] // Plotting the Decycler return decycler AS "Decycler"

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

  // Input parameters length = 60 src = close   // Constants once PI = 3.141592653589793   // Variables PIx2Length = 2 * PI / length cosValue = cos(PIx2Length)   alpha = 0 If (cosValue <> 0) then    alpha = (cosValue + sin(PIx2Length) - 1) / cosValue else    If (barindex > 1) then       alpha = alpha[1]    endif endif   decycler = alpha / 2 * (src + src[1]) + (1 - alpha) * decycler[1]   // Plotting the Decycler return decycler AS "Decycler"

  I would appreciate if someone could point me to my mistake(s).

  Thanks JS!

  Although the indicators share the same name, the calculation is not the exactly the same.

  True, but all the Decyclers I’ve seen have a different calculation… 🙂

  It’s such a difficult subject that I can’t judge which calculation is the right one…

  You only have to convert radians to degrees.

  PIx2Length=2*PI/length transf = PIx2Length*360/(2*PI) cosine=COS(transf)

  1 2 3

  PIx2Length=2*PI/length transf = PIx2Length*360/(2*PI) cosine=COS(transf)

  PRT works with degrees and TV works with radians. Here you have the code:

  //-----Inputs------------------------------------// length=60 src=close colorMA=1 //-----------------------------------------------// //-----Moving average calculation----------------// once PI = 3.14159265359 if barindex > length then PIx2Length=2*PI/length transf = PIx2Length*360/(2*PI) cosine=COS(transf) alpha=0 if cosine<>0 then alpha=(cosine+sin(transf)-1)/cosine else alpha=alpha[1] endif MA=0 MA=alpha/2*(src+src[1])+(1-alpha)*MA[1] //-----------------------------------------------// //-----Color MA configuration--------------------// if colorMA then if MA>MA[1] then r=0 g=255 elsif MA<MA[1] then r=255 g=0 endif endif endif return MA as "Decycler" coloured(r,g,0)style(line,2)

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

  //-----Inputs------------------------------------// length=60 src=close colorMA=1 //-----------------------------------------------// //-----Moving average calculation----------------// once PI = 3.14159265359   if barindex > length then   PIx2Length=2*PI/length transf = PIx2Length*360/(2*PI)   cosine=COS(transf) alpha=0   if cosine<>0 then alpha=(cosine+sin(transf)-1)/cosine else alpha=alpha[1] endif   MA=0 MA=alpha/2*(src+src[1])+(1-alpha)*MA[1] //-----------------------------------------------// //-----Color MA configuration--------------------// if colorMA then if MA>MA[1] then r=0 g=255 elsif MA<MA[1] then r=255 g=0 endif endif endif   return MA as "Decycler" coloured(r,g,0)style(line,2)
