Problem mit dem Farbwechsel eines Indikators

 

Hallo zusammen,

ich versuche grade den Mayer Multiple Indikator nachzubauen. Als Linienindikator habe ich das geschafft, allerdings hänge ich grade bei der zweiten Version. In diesem Indikator soll der Wert als Säule dargestellt werden, welche Ihre Farbe wechselt wenn ein bestimmter Wert unter- bzw. überschritten wird.

Wenn ich den Indikator anwende bekomme ich entweder Säulen in nur einer Farbe, oder gar keine Säulen ausgedruckt. Habt ihr mir evtl einen Tipp, woran es liegen kann?

Hallo!

  1. Bitte benutze die Code-Taste aus der Editierzeile (</>) bzw. Alt+s um Code zu veröffentlichen.
  2. Für unterschiedliche Farben ein und desselben Indikatorpuffers muss man für jede Farbe einen eigenen Puffer verwenden!
  3. Oder man verwendet einzelne Objekte, was alles ziemlich verlangsamt!!!

Wenn du ein färbiges Histogramm möchtest must du

#property indicator_type1   DRAW_LINE

als

#property indicator_type1   DRAW_COLOR_HISTOGRAM

definieren

Du brachst dann noch eine andere Definition für die Farben.

Such dir irgend ein Beispiel wo DRAW_COLOR_LINE oder DRAW_COLOR_HISTOGRAM verwendet wird.

Un schau dir das verhalten dieses Indis im Tester an. Im EA ist Bar[0] mit Vorsicht zu verwenden.

Da jede neue Bar gleiche Werte für O,H,L,C hat beginnt der ForceIndex bei einer neuen Bar IMMER bei 0.

Ist trotzdem ein interessanter (und einfacher) Indi.
 

Damit meine Indikatorkenntnisse nicht einrosten habe ich mich an dem Force_Index probiert.

Das Ergebnis: Wahlweise Linien, Farblinien, Histogram, Farbhistogramm. Alle Indikator-Eigenschaften sind dynamisch erstellt, damit einstellbar.
