how to get indicator color, now i only can get the value, but the one line indicator have two color (sometime is RED,Sometime is Green)

To my knowledge (and I'd love someone to tell me I'm wrong, and how to do it) it's not possible to extract colours from another indicator via iCustom.

Note that, if the indicator swaps between red & green, then that 'swap' info is available as (probably) 2 indicator values (different modes in the iCustom code), either one or the other (e.g red or green histogram), or else one higher than other (e.g. Candle body/wick colour)

To color an indicator uses multiple buffers (one per color at least) You'll need to find which buffer corresponds to which color and what value corresponds to don't paint.

Thanks

i copy the the code in here(it copy from anotherwebsite),anyone can help me how to get color buffers

Hi Pclovec,

Match up your "Property Indicator Buffers" with your "Draw" Buffers to find the colors for each buffer...

Example -

#property indicator_buffers 5
#property indicator_color1 Lime = [draw] buffer 0
#property indicator_color2 Red = [draw] buffer 1
#property indicator_color3 Lime = [draw] buffer 2
#property indicator_color4 Red = [draw] buffer 3
#property indicator_color5 Gold = [draw] buffer 4

You can also Print the values in the log or Display them on the screen as Comments to confirm the buffers.

Hope this helps,
Robert

Thanks you help,i have debug the code. and find out,the color1 and color2 line is my look at.

1. color1 Line buffer is my RSI Lline,

2.Color2 is DnRSI is second Line

my problem:

i want to when color2 line start to draw give me sign and when it finish draw also give me sign,i i tried to change the code,but seems the sign is not rights.

later i want to write a EA to read these sign to trade.

 if (dn==true)
      {
         
         if (RSI[shift]>BullLevel) 
         {
            dn=false;
            DnRSI[shift]=EMPTY_VALUE;
           
         }
         else
         {
            dn=true;
            DnRSI[shift]=RSI[shift];
            Buy[shift]=ob; //add 
         }
       

      }
      else
      {
         if (RSI[shift]<BearLevel) 
         {
            dn=true;
            DnRSI[shift]=RSI[shift];
            Sell[shift]=os; //  add 
            
         }
         else
         {
            dn=false;
            DnRSI[shift]=EMPTY_VALUE;
         }
         
      }
