How to paint "Close[i]/High[i]" in seperate window?

[inssuc]

hi everyone, when i try to draw a line of "(Close-Low)/(High-Low)", i get a very strange result. to my opinion, the line will wave between 0 and 1, but actual result is a straint line, i'm puzzled, can some one explain this?

here is my simple code:

//-----------------------------------------

#property indicator_separate_window

#property indicator_buffers 1

#property indicator_color1 White

double buffer1[];

int CountedBars=0;

int init()

{

SetIndexBuffer(0,buffer1);

return(0);

}

int start()

{

CountedBars=IndicatorCounted();

if(Bars<1) return(0);

for(int i=Bars-CountedBars;i>=0;i--)

{

buffer1=(Close-Low)/(High-Low);

}

}
