Cross over ou under highest/lowest support et résistance indacteur

  Bonjour,

  J’aimerais avoir une indication sur mon graphique lorsque le prix d’une bougie va traverser un support défini à l’avance dans un tableau.

  Voici le code que j’ai écris avec comme exemple: si le plus haut d’une bougie vient a croisé un support ou une résistance nous avons une indication sur le graphique.

  Indicateur support and resistance crossed

  /////////////////Resistance /////////////////////////// if close>=highest[length1](close) then t1 = 0 top1 = close else top1 = top1 t1 = t1+1 if t1>lenght2 and t1<lenght2+2 then $TOPy[lastset($TOPy)+1] = top1 endif ENDIF /////////////////Support /////////////////////////// if close<=lowest[length1](close) then b1 = 0 bot1 = close else bot1 = bot1 b1 = b1+1 if b1>lenght2 and b1<lenght2+2 then $boty[lastset($boty)+1] = bot1 endif endif ///////////////////////////////////Conditions baissière/////////////////////////////////// for s=0 to 15 do if highest[1](high) CROSSES OVER $BOTy[s] or highest[1](high)CROSSES UNDER $BOTy[s] or highest[1](high) CROSSES OVER $TOPy[s]or highest[1](high)CROSSES UNDER $TOPy[s] then if ViewArrow then DRAWARROWDOWN(barindex[p],(high[p]+(Margin*MultiplicateurFleche))) COLOURED(ColorR,ColorV,ColorB) endif ENDIF NEXT return

  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

  /////////////////Resistance /////////////////////////// if close>=highest[length1](close) then t1 = 0 top1 = close else top1 = top1 t1 = t1+1 if t1>lenght2 and t1<lenght2+2 then $TOPy[lastset($TOPy)+1] = top1 endif ENDIF /////////////////Support /////////////////////////// if close<=lowest[length1](close) then b1 = 0 bot1 = close else bot1 = bot1 b1 = b1+1 if b1>lenght2 and b1<lenght2+2 then $boty[lastset($boty)+1] = bot1 endif endif ///////////////////////////////////Conditions baissière/////////////////////////////////// for s=0 to 15 do if highest[1](high) CROSSES OVER $BOTy[s] or highest[1](high)CROSSES UNDER $BOTy[s] or highest[1](high) CROSSES OVER $TOPy[s]or highest[1](high)CROSSES UNDER $TOPy[s] then if ViewArrow then DRAWARROWDOWN(barindex[p],(high[p]+(Margin*MultiplicateurFleche))) COLOURED(ColorR,ColorV,ColorB) endif ENDIF NEXT return

  J’ai mis ci joint un screen d’un exemple de situation dans laquelle j’aimerais avoir une indication (La ligne rouge est la matérialisation du premier indicateur de support et résistance).

  J’ai beau essayer tous les type de cross over ou under (sur le close, sur le high, sur le highest[1] (high)) rien n’y fait, je n’ai jamais de flèche qui apparait. Je suis dans une impasse.

   

  Merci de votre aide

  Hola, il a légèrement adapté votre code :

  defparam drawonlastbaronly = true length1=20 lenght2=40 /////////////////Resistance /////////////////////////// if close>=highest[length1](close) then t1 = 0 top1 = close else top1 = top1 t1 = t1+1 if t1>lenght2 and t1<lenght2+2 then $TOPy[t+1] = top1 $TOPx[t+1] = barindex t=t+1 endif ENDIF /////////////////Support /////////////////////////// if close<=lowest[length1](close) then b1 = 0 bot1 = close else bot1 = bot1 b1 = b1+1 if b1>lenght2 and b1<lenght2+2 then $boty[r+1] = bot1 $botx[r+1] = barindex r=r+1 endif endif ////////////Conditions baissière/////////////////////////////////// if islastbarupdate then for j=1 to barindex do for i=r downto max(0,r-15) do if barindex[j]>$botx[i] and low[j] < $BOTy[i] and low[j-1] > $BOTy[i] then DRAWARROWDOWN(barindex[j],$BOTy[i]) COLOURED("red") break ENDIF NEXT for s=t downto max(0,t-15) do if barindex[j]>$TOPx[s] and high[j] > $TOPy[s] and high[j-1] < $TOPy[s]then DRAWARROWup(barindex[j],$TOPy[s]) COLOURED("green") break endif next next endif return $boty[r] coloured("red"),$TOPy[t] coloured("blue")

  Merci beaucoup Ivan, j’ai travaillé toute la journée pour implémenter cette condition dans mon algorithme.

  J’ai une dernière question. Est-il possible de supprimer une donnée d’un tableau après x période pour qu’elle ne soit prisent en compte dans les conditions.

  Voici comment j’ai modifier pour qu’il fonctionne dans mon algorithme.

  Alerte on supports and resistances

  Bonjour, Pour réinitialiser les données d'un tableau, vous pouvez utiliser unset . D'un autre côté, pour réinitialiser une valeur particulière, vous pouvez l'écraser.
