Indicator - 2nd line is not displayed

New comment
 

Hi,

 I coded my first indicator. I am trying to show the 2 values of the indicator in one seperate values with 2 separate lines. but only the first line is drawn. The 2nd Buffer contains the correct values and one can see the values in the data window. just the line is not drawn.

I guess there is a very easy solution, but since it is my first own code I can't find the problem 

 Please help me out. thanks!

Hi


You also need to define the number of indicator plots and line types, see this example.

I think this will solve your problem.

#property indicator_separate_window
#property indicator_buffers 2
#property indicator_plots   2

#property indicator_type1   DRAW_LINE
#property indicator_color1  clrAqua
#property indicator_style1  STYLE_DASHDOTDOT
#property indicator_width1  1
#property indicator_label1  "USD"

#property indicator_type2   DRAW_LINE
#property indicator_color2  clrYellow
#property indicator_style2  STYLE_DASHDOTDOT
#property indicator_width2  1
#property indicator_label2  "EUR"
