  Bonjour,

  Su TV, j’utilise un TSI avec parametres 34.5.13 (affichage en point pour ligne parametre 3 et le signal en rouge ligne pleine, voir photo jointe) dont voici le code :

  //@version=5 indicator("True Strength Indicator", shorttitle="TSI", format=format.price, precision=4, timeframe="", timeframe_gaps=true) long = input(title="Long Length", defval=25) short = input(title="Short Length", defval=13) signal = input(title="Signal Length", defval=13) price = close double_smooth(src, long, short) => fist_smooth = ta.ema(src, long) ta.ema(fist_smooth, short) pc = ta.change(price) double_smoothed_pc = double_smooth(pc, long, short) double_smoothed_abs_pc = double_smooth(math.abs(pc), long, short) tsi_value = 100 * (double_smoothed_pc / double_smoothed_abs_pc) plot(tsi_value, color=#2962FF) plot(ta.ema(tsi_value, signal), color=#E91E63) hline(0, title="Zero", color=#787B86)

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

  //@version=5 indicator("True Strength Indicator", shorttitle="TSI", format=format.price, precision=4, timeframe="", timeframe_gaps=true) long = input(title="Long Length", defval=25) short = input(title="Short Length", defval=13) signal = input(title="Signal Length", defval=13) price = close double_smooth(src, long, short) => fist_smooth = ta.ema(src, long) ta.ema(fist_smooth, short) pc = ta.change(price) double_smoothed_pc = double_smooth(pc, long, short) double_smoothed_abs_pc = double_smooth(math.abs(pc), long, short) tsi_value = 100 * (double_smoothed_pc / double_smoothed_abs_pc) plot(tsi_value, color=#2962FF) plot(ta.ema(tsi_value, signal), color=#E91E63) hline(0, title="Zero", color=#787B86)

   

  Ensuite sur ce même indicateur j’applique une SMA50 basé sur le TSI 3 (en points)
  Code TV :

  //@version=5 indicator(title="Moving Average", shorttitle="MA", overlay=true, timeframe="", timeframe_gaps=true) len = input.int(9, minval=1, title="Length") src = input(close, title="Source") offset = input.int(title="Offset", defval=0, minval=-500, maxval=500) out = ta.sma(src, len) plot(out, color=color.blue, title="MA", offset=offset) ma(source, length, type) => switch type "SMA" => ta.sma(source, length) "EMA" => ta.ema(source, length) "SMMA (RMA)" => ta.rma(source, length) "WMA" => ta.wma(source, length) "VWMA" => ta.vwma(source, length) typeMA = input.string(title = "Method", defval = "SMA", options=["SMA", "EMA", "SMMA (RMA)", "WMA", "VWMA"], group="Smoothing") smoothingLength = input.int(title = "Length", defval = 5, minval = 1, maxval = 100, group="Smoothing") smoothingLine = ma(out, smoothingLength, typeMA) plot(smoothingLine, title="Smoothing Line", color=#f37f20, offset=offset, display=display.none)

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

  //@version=5 indicator(title="Moving Average", shorttitle="MA", overlay=true, timeframe="", timeframe_gaps=true) len = input.int(9, minval=1, title="Length") src = input(close, title="Source") offset = input.int(title="Offset", defval=0, minval=-500, maxval=500) out = ta.sma(src, len) plot(out, color=color.blue, title="MA", offset=offset)   ma(source, length, type) => switch type "SMA" => ta.sma(source, length) "EMA" => ta.ema(source, length) "SMMA (RMA)" => ta.rma(source, length) "WMA" => ta.wma(source, length) "VWMA" => ta.vwma(source, length)   typeMA = input.string(title = "Method", defval = "SMA", options=["SMA", "EMA", "SMMA (RMA)", "WMA", "VWMA"], group="Smoothing") smoothingLength = input.int(title = "Length", defval = 5, minval = 1, maxval = 100, group="Smoothing")   smoothingLine = ma(out, smoothingLength, typeMA) plot(smoothingLine, title="Smoothing Line", color=#f37f20, offset=offset, display=display.none)

   

  Est-il possible d’obtenir une transcription de ces 2 codes en un seul pour PRT ?
  Le top serait d’avoir les parametres de chaque signal modifiable par le menu de l’indicateur directement au lieu d’aller dans le code a chaque fois.
  Avec le TSI proposé sur PRT en natif je n’obtiens pas les mêmes choses.

  En vous remerciant

  L’indicateur TSI se trouve ici: True Strength Index TSI

  On peut lui appliquer une moyenne mobile via la liste des indicateurs de la plateforme ensuite.

  Merci Nicolas pour le retour d’infos, mais j’ai testé avec ces indicateurs mais je n’obtiens pas les mêmes choses.

  Ci-dessous le code de cette version du TSI convertit pour ProRealTime.

  //"True Strength Indicator" long = 25//Long Length short = 13 //Short Length signal = 13 //Signal Length iprice = close pc = Variation(iprice) doublesmoothedpc = average[short,1](average[long,1](pc)) doublesmoothedabspc = average[short,1](average[long,1](abs(pc))) tsivalue = 100 * (doublesmoothedpc / doublesmoothedabspc) return tsivalue coloured(41, 98, 255),average[signal,1](tsivalue) coloured(233, 30, 99),0 coloured(120, 123, 134)

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

  //"True Strength Indicator" long = 25//Long Length short = 13 //Short Length signal = 13 //Signal Length iprice = close   pc = Variation(iprice) doublesmoothedpc = average[short,1](average[long,1](pc)) doublesmoothedabspc = average[short,1](average[long,1](abs(pc)))   tsivalue = 100 * (doublesmoothedpc / doublesmoothedabspc)   return tsivalue coloured(41, 98, 255),average[signal,1](tsivalue) coloured(233, 30, 99),0 coloured(120, 123, 134)

  Tu n’as plus qu’a appliquer la moyenne mobile de ton choix sur la valeur de l’indicateur.
