Need help to built a simple indicator

Hi,

Can anyone help me to built a simple indicator for metatrader, that wil indicates if it closes more than x% value from the range for both bars, down bar and up bar?

Eg.

For bullish bar
High = 1.21
low = 1.01
open = 1.03
close = 1.13
x% = let say 55%

range = 20
55% = 11

so in this case, its a bullish bar coz it closes more than 1.12, its vise versa for bearish bar.

So the moment, the bar closes, above or below the x% of the range, it will change the color for the bar, maybe red for bearish bar, and green for bullish bar.

Hopefully this indicator will benefits others as well...

Thank you in advance
