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);

}

}

if(Bars<1) return(0);

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

{

if( (Close-Low) > 0 && (High-Low) > 0 )

}

}

add

if( (Close-Low) > 0 && (High-Low) > 0 )

above : if( (Close-Low) > 0 && (High-Low) > 0 )

like :

{

if( (Close-Low) > 0 && (High-Low) > 0 )

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

}

thanks

it works, thanks! but i still don't understand why the condition "High-Low>0" is needed? can High<=Low in sometime?

And, the line should be painted anyway, the condition is just tell mt4 when draw when not draw, why mt4 don't draw without the condition?

High may equal Low (first tick of a bar, or volume = 1 bar) then you divide by zero and the indic stops working.
