Background1_color = colortan;
Background2_color = colorrose;
 
I included that by habit as I was going to parameterize things.

  Hi Andre,
   
  I don't know about in ALF, but in AFL <vbg> it's certainly possible 
  and easy.  I'm assuming you want the entire chart to have a different 
  color when the condition is true and another color when false, rather than 
  just the indicator changing color.  So you can try the 
  following:
   
  XX = C;  // substitute your value here
   
  Indicator1 = MA(c, 5);
  Indicator2 = MA(c, 20); 
  Indicator3 = MA(c, 50); 
   
  Indicator1_Color = colorblue; 
  Indicator2_Color = colorred;
  Indicator3_Color = colorplum; 
   
  plot(c, "CLOSE", colorblack, stylecandle); 
   
  Plot(Indicator1, "Indicator 1", Indicator1_color, styleline );
  Plot(Indicator2, "Indicator 2", Indicator2_color, styleline );
  Plot(Indicator3, "Indicator 3", Indicator3_color, styleline );
   
   
  Background1_color = colortan;
  Background2_color = colorrose;
   
  Cond1 = indicator3 > XX;
  cond2 = indicator3 < XX; 
   
  Plot(100, "Close vs Indicator 3", 
      iif(cond1, colortan,
      iif(cond2, colorrose,
      colordefault )), 
  styleownscale|stylearea|stylenolabel|stylenotitle, 0 , 100, 0, -5);
   
   
  I wrote the above on the fly (didn't write it within the formula 
  editor), however it should work fine unless there is a word-wrap issue. Let me 
  know if this is what you want.  For demonstration purposes I simply made 
  the indicators to be moving averages with some default periods and the value 
  the close of the instrument.  Substitute your own value for XX and 
  indicators for the MAs. Similarly you may pick your own colors to suit you. 
  Didn't bother to parameterize anything as I don't know what you are really 
  doing or what you are trading.

Hi Guys,
I need to know if the following is possible in 
    ALF.
I have 3 indicators and a price chart on my screen. When the 
    bottom indicator drops below a specified value, I would like to highlight in 
    colour this area, however, the colour must extend through the other two 
    indicators and over the price chart.
Does anyone have a clue how to 
    do 
    this?
cheers
Andre
