  Hi all.

  Is there somebody that can convert John Ehlers’ Sinewave Indicator forPRT usage? This is the EasyLanguage code:

  Hi Renato,

  Do this one the same? : http://www.prorealcode.com/prorealtime-indicators/even-better-sinewave/

  I believe not, but just to be sure? If not, I can of course convert it to prorealtime.

  Hi Nicholas

  No, I had already seen this one and it is not the same; the Ehlers’ script that I forwarded is much more complicated.

  Thanks for your dedication to the cause LOL.

  Hi Renato,

  I am also very interested in the Hilbert Sine Wave indicator by John Ehler and I would like to be able to use this with PRT. There is the “Better Hilbert Sine Wave indicator” by emini-watch.com, which is only available for TradeStation. I expect you have seen this, but if not here is the link – http://emini-watch.com/trading-indicators/hilbert-sine-wave/

  It would be perfect to have a version of this for PRT. Have you tested the code that Nicolas very kindly provided? Did he manage to code the EasyLanguage code that you provided?

  Regards,

  Tony

  Hello

  I have found an interesting concept on this website  (it is not an advertising, just a link to the concept)

  https://www.pro-indicators.com/pro-indicators—sinewave—momentum-on-tradingview-en.html

  I am manually trading cycle of Elliot Waves

  The idea of trading sinewave cycles combined with other information is smart.

  I would like to build a screener based on

  -sinewave cycles

  -momentum (divergence)

  -price pattern : Demark count 9 /13 , or high volume , candlestick patterns, POC on market profile

  -fibonnaci retracement of previous trend

  Is there anybody who tried to code this kind of indicator / screener?

   

  Regards

  I have worked on

  -cycle on adaptative stochastic

  -basic candle sticks : Low/High reversal, Extreme Reveral, Reversal

  It give some results

   

  I will try to add

  -better volume indicator

  -momentum filtration

  Hello Nicolas,

  I was attempting to improve/replace the conditions in Candle Reverse Sinewave and use a (fractal) reversal of this original line of code:

  3 bar rounding bottom

  if ScanBuyCondition then if low[1]<Low[2] and Low[1]<low[0] then DRAWARROWUP(barindex[1],low[1])coloured(76,153,0) Endif

  1 2 3 4

  if ScanBuyCondition then if low[1]<Low[2] and Low[1]<low[0] then   DRAWARROWUP(barindex[1],low[1])coloured(76,153,0) Endif

  using lines from this Fractal code:
  https://www.prorealcode.com/topic/calculating-diagonal-trend-lines-using-fractals-and-trigonometry/page/2/#post-59358

  Fractal Reverse

  defparam calculateonlastbars=10000   //Calculate Fractal (Swing Point)   once FracH = 0 //initialize fractal count once FracL = 0 //initialize fractal count   For i = 0 to 4 Do If high[2] > high[i] Then //look for high fractal with 2 lower highs on either side FracH = FracH + 1 EndIf If low[2] < low[i] Then //look for low fractal with 2 higher lows on either side FracL = FracL + 1 EndIf Next   If FracH = 4 Then //High Fractal Identified If Bear = 0 and Bull = 0 Then Bear = 1 //Initialize first trend direction EndIf FractalH = high[2] //High Fractal Price Level FractalP = barindex - 2 //High Fractal Bar Position EndIf If FracL = 4 Then //Low Fractal Identified If Bear = 0 and Bull = 0 Then Bull = 1 //Initialize first trend direction EndIf FractalL = low[2] //Low Fractal Price Level FractalP = barindex - 2 //Low Fractal Bar Position EndIf   FracH = 0 //reset fractal count FracL = 0 //reset fractal count

  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

  defparam calculateonlastbars=10000   //Calculate Fractal (Swing Point)   once FracH = 0 //initialize fractal count once FracL = 0 //initialize fractal count   For i = 0 to 4 Do   If high[2] > high[i] Then //look for high fractal with 2 lower highs on either side FracH = FracH + 1 EndIf   If low[2] < low[i] Then //look for low fractal with 2 higher lows on either side FracL = FracL + 1 EndIf Next   If FracH = 4 Then //High Fractal Identified If Bear = 0 and Bull = 0 Then Bear = 1 //Initialize first trend direction EndIf   FractalH = high[2] //High Fractal Price Level FractalP = barindex - 2 //High Fractal Bar Position EndIf   If FracL = 4 Then //Low Fractal Identified If Bear = 0 and Bull = 0 Then Bull = 1 //Initialize first trend direction EndIf   FractalL = low[2] //Low Fractal Price Level FractalP = barindex - 2 //Low Fractal Bar Position EndIf   FracH = 0 //reset fractal count FracL = 0 //reset fractal count

  How do I correct the syntax below to get it to draw the green arrows when this line: FracL = FracL + 1 is used?

  Williams Fracta Bottom

  //Calculate Fractal (Swing Point) once FracH = 0 //initialize fractal count once FracL = 0 //initialize fractal count For i = 0 to 4 Do if ScanBuyCondition then If low[2] < low[i] Then //look for low fractal with 2 higher lows on either side FracL = FracL + 1 Endif if FracL then DRAWARROWUP(barindex[1],low[1])coloured(76,153,0) Endif

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

  //Calculate Fractal (Swing Point)   once FracH = 0 //initialize fractal count once FracL = 0 //initialize fractal count   For i = 0 to 4 Do   if ScanBuyCondition then If low[2] < low[i] Then //look for low fractal with 2 higher lows on either side FracL = FracL + 1 Endif   if FracL then DRAWARROWUP(barindex[1],low[1])coloured(76,153,0) Endif

  I’m hoping that this newer coding will produce less false signals than the original, do you think this is the best reversal pattern to use (a 5 bar pattern)?

  I’ve have experimented a lot with different Ehler’s Stochastic periods and thresholds (0.01 up to 0.3) and although this is a great indicator (arrows literally on some turning points) there’s just too many false signals (eg, a few green arrows in a falling market) and it still misses some big turning points.

  Cheers!

  Hi Bard, I literally just scanned through your request. But here is an updated version of the Fractal code above:

  //Shoulder = 3 //size of shoulders r = ShoulderSize*2 once SwingH = 0 once SwingL = 0 once FractalD = 0 For i = 0 to r Do If high[ShoulderSize] > high[i] or i = ShoulderSize Then SwingH = SwingH + 1 EndIf If low[ShoulderSize] < low[i] or i = ShoulderSize Then SwingL = SwingL + 1 EndIf Next atr = averagetruerange[r*2] If SwingH = (r+1) and (FractalD = 0 or FractalD = -1) Then FractalH = high[ShoulderSize] drawtext("▼",barindex[ShoulderSize],FractalH+atr*3,dialog,bold,20) coloured(25,25,112) FractalD = 1 EndIf If SwingL = (r+1) and (FractalD = 0 or FractalD = 1) Then FractalL = low[ShoulderSize] drawtext("▲",barindex[ShoulderSize],FractalL-atr*3,dialog,bold,20) coloured(176,23,31) FractalD = -1 EndIf SwingH = 0 SwingL = 0 return// FractalH coloured(0,255,0) as "High Fractal", FractalL coloured(255,0,0) as "Low Fractal"

  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

  //Shoulder = 3 //size of shoulders   r = ShoulderSize*2   once SwingH = 0 once SwingL = 0 once FractalD = 0   For i = 0 to r Do If high[ShoulderSize] > high[i] or i = ShoulderSize Then SwingH = SwingH + 1 EndIf If low[ShoulderSize] < low[i] or i = ShoulderSize Then SwingL = SwingL + 1 EndIf Next   atr = averagetruerange[r*2]   If SwingH = (r+1) and (FractalD = 0 or FractalD = -1) Then FractalH = high[ShoulderSize] drawtext("▼",barindex[ShoulderSize],FractalH+atr*3,dialog,bold,20) coloured(25,25,112) FractalD = 1 EndIf If SwingL = (r+1) and (FractalD = 0 or FractalD = 1) Then FractalL = low[ShoulderSize] drawtext("▲",barindex[ShoulderSize],FractalL-atr*3,dialog,bold,20) coloured(176,23,31) FractalD = -1 EndIf   SwingH = 0 SwingL = 0   return// FractalH coloured(0,255,0) as "High Fractal", FractalL coloured(255,0,0) as "Low Fractal"

  Wow! This is is amazing, thanks @Juanj,

  I’ve compared your fractal indicator to the modified “reversal point indicator” and my modified version – pls see image 1 of daily S&P 500. Shouldersize =5

  The original indicators arrows are bright green and red.
  My Univ Osc modified indicator uses dark green and orange arrows and
  the fractal indicator uses green and purple triangles.

  I used a Call code for Ehler’s Universal Oscillator to replace the standard oscillator in the original “reversal point indicator” (my code at the bottom of the comments section of the indicator here: https://www.prorealcode.com/prorealtime-indicators/reversal-point-indicator/)

  I had a couple of questions though, I’m just not sure how to do a substitution using the fractal code for this old c3  = lowest[3](low)<lowest[LowestLow](low)[1] etc, line of the code?

  And if you wanted to do a simplified creation I was wondering why I set it to Buy when Price = FractalL, it doesn’t produce any trades? Pls see second image.

  Also lastly why are the Return Fractal H and Fractal L lines a few bars to the right of the drawarrows on the price chart, i.e. not aligned with the drawarrows?

  Thanks again,

  Cheers,
  Stay safe!
