    En quoi consiste cet indicateur : Swapping Trendline area 3 ?

    Malgré la saisie show S/R en début de code, pas d’affichage graphique !?

    Il faut appliquer l’indicateur sur le prix.

    Dans le code ci-dessus il te manque la variable lookback à ajouter en tête de code:

    lookback = 10

    Bonjour, J’ai une question concernnant les lignes de tendance, pourrions-nous appliquer la même idée de rupture de ligne de tendance au RSI? À quoi ressemblerait le code? Merci à tous.

    Le code ci-dessous trace les lignes de trendline sur l’indicateur RSI. On peut changer l’indicateur avec n’importe quel autre dans la variable “source”.

    defparam drawonlastbaronly = true
defparam calculateonlastbars = 500
lookback = 20
showSR = 0

source = rsi[14]

//fractals
cp = lookback
if source[cp] >= highest[(cp)*2+1](source) then
LLH = 1
else
LLH = 0
endif
 
if source[cp] <= lowest[(cp)*2+1](source)  then
LLL = -1
else
LLL = 0
endif
 
if LLH = 1 then
oldLTOPy = LTOPy[1]
oldLTOPx = LTOPx[1]
LTOPy = source[cp]
LTOPx = barindex[cp]
endif
 
if LLL = -1 then
oldLBOTy = LBOTy[1]
oldLBOTx = LBOTx[1]
LBOTy = source[cp]
LBOTx = barindex[cp]
endif
 
//trend line
DRAWLINE(oldLTOPx,oldLTOPy,LTOPx,LTOPy)coloured(112,169,161)
DRAWLINE(oldLBOTx,oldLBOTy,LBOTx,LBOTy)coloured(211,78,36)
 
//support/resistance
if showSR then
DRAWHLINE(LTOPy) COLOURED(207,215,199,100)
DRAWHLINE(LBOTy) COLOURED(207,215,199,100)
endif
 
 
barelapsedTOP=barindex-LTOPX
barelapsedBOTTOM=barindex-LBOTX
 
factorTOP = (LTOPy-oldLTOPy)/(LTOPx-oldLTOPx)
factorBOTTOM = (LBOTy-oldLBOTy)/(LBOTx-oldLBOTx)
 
//drawtext("#factor#",barindex,low-10*pipsize,Dialog,Bold,20)
 
nowTOP = LTOPy+(barelapsedTOP*factorTOP)
drawtext("X",barindex,nowTOP,Dialog,Bold,20) coloured(112,169,161)
 
nowBOTTOM = LBOTy+(barelapsedBOTTOM*factorBOTTOM)
drawtext("X",barindex,nowBOTTOM,Dialog,Bold,20) coloured(211,78,36)
 
RETURN source as "indicator", nowTOP coloured(110,0,0,0), nowBOTTOM coloured(110,0,0,0)

    Bonjour, Merci pour la réponse, je teste avec ce code d’un partenaire.
    Et j’aimerais savoir comment je pourrais faire un dépistage en petits groupes avec cet indicaur.
    Merci encore.
