Je pense que le problème vient de la variable `color`. Elle est utilisée dans deux instructions conditionnelles, et la seconde écrase la première.

// --- parameters
sensitivity = 150
fastLength = 20
slowLength = 40
channelLength = 20
mult = 2.0
deadZone = 30

IF barindex > slowLength THEN
   calcMACD = MACD[fastLength,slowLength,9](customclose)
   calcBBUpper = average[channelLength](customclose) + (mult * std[channelLength](customclose))
   calcBBLower = average[channelLength](customclose) - (mult * std[channelLength](customclose))
   
   t1 = (calcMACD - calcMACD[1]) * sensitivity
   e1 = calcBBUpper - calcBBLower
   
   IF t1 >= 0 THEN
      trendUP = t1
      trendDOWN = 0
   ELSE
      trendUP = 0
      trendDOWN = -1 * t1
   ENDIF
   
   IF trendUP > 0 THEN
      IF trendUP  0 THEN
      IF trendDOWN < trendDOWN[1] THEN
         downR = 255
         downG = 165
         downB = 0
      ELSE
         downR = 255
         downG = 0
         downB = 0
      ENDIF
   ENDIF
ENDIF

RETURN trendUP COLOURED(upR, upG, upB) STYLE(histogram) AS "UP", trendDOWN COLOURED(downR, downG, downB) STYLE(histogram) AS "DOWN", e1 AS "Explosion line", deadZone * pipsize AS "Dead Zone Line"

Bonjour à tous et merci d’avoir bossé sur le waddah attar, indicateur que j’utilise beaucoup

J’ai quand même un problème qui ne devrait pas en être un pour vous, la sensibilité de l’histogramme ne correspond pas du tout à celle du waddah attar explosion V2 SHK que j’utilise sur tradingview, et la dead line n’est pas fixe.

En revanche la courbe de signal est parfaite.

Merci de votre aide cela m’éviterais d’avoir 1 écran prorealtime et un autre tradingview…

voici la version que j’utilise
