Narrow Range Indicator

I need a MT4 indicator which will point to a bar which has a narrower range (H-L) than any of the six preceding bars. The pattern will be 7 bars total.
I found one online, but it doesn't work- it isn't accurate.
Thanks for your help.

hi

attached the picture for example
rule 1: narrow rage 4(nr4) = last candle4 <next3<next 2<next 1 . it is mentioned in orange clour with 4.

if that nr4 candle is inside compare to before candle that is ''nr4 inside' and mentioned "" orange colur star""


rule 2: narrow rage 7(nr7) = last candle7 <next6<next 5<next4<next3<next 2<next 1 . it is mentioned in green clour with 7.

if that nr7 candle is inside compare to before candle that is ''nr7 inside' and mentioned "" green colur star""
rule 3: normal inside candle is mention as yellow round

Here you go, they invented this one


Narrow range patterns come from Tony Crabel's book, Day Trading with Short Term Price Patterns & Opening Range Breakout. Even though the book, which was published in 1990, is currently out of print, many of its ideas are still effective. In particular, the NR4 (Narrow Range 4) and NR7 (Narrow Range 7) patterns are quite popular with short-term traders. The philosophy behind the pattern is similar to the Bollinger Band Squeeze, that being that a volatility contraction is often followed by a volatility expansion. Narrow range days mark price contractions that often precede price expansions. Even though Crabel traded mainly futures, traders can apply these techniques to stocks, indices and ETFs.

I reckon it will work, your comments, suggestions, criticism all welcomed
