Indicator color change based on a condition

New comment
 
Is it possible to change the color of an indicator based on a condition?

for example:

       if (momentum1>0) 
       {
            SetIndexStyle(0,DRAW_LINE,STYLE_SOLID,1,Lime);          
       }
       if (momentum1<0) 
       {
            SetIndexStyle(0,DRAW_LINE,STYLE_SOLID,1,Red);          
       }
       Plot0[shift]=momentum1;



I know some coders are using 2 indicator buffers, but would be great if we can change the color of an indicator as i explained (The above example doesnt work, may be iam missing something).

Thanks in advance for any help.

I forgot to mention that this is outside the Init() function, the change color code is on Main() function.

color is set for whole line only. you need for 2 buffers - first for momemntum1>0, second for momentum1<0 (and what about momentum1==0?)
 
Thanks Slawa.

Oh Slawa, i didnt responded your question about momentum1==0, if its cero then doesnt matter, i prefer to dont plot at cero value because i only want to see above or bellow cero level (on this case of course).
