How can I optical mark my indicator

 

hi,

I have programmed an indikator with many lines. Now I am searching for a good way to mark a buy or sell signal optically.

First I thought about a history diagramm in a new window, but therefore I need an additional indikator.

Do you have any ideas, how I can mark this in a clear way.

I it possible to marks the background color of the timeline green and red for the times the signal is valid?

Lot's of thanks!

 

I would paint a wingding above or below the bar using code something like

   SetIndexStyle( 0,DRAW_ARROW, EMPTY, indicator_width1, indicator_color1);
   SetIndexArrow( 0,35);
   SetIndexBuffer(0,V1Buff);

(35 is a scissors, which I use to denote missing bars)

Reason:
