I can give it a shot:
The current ATR take a period input that can only be a constant, such
as ATR(14). The new ATR will accept an ARRAY as input.
Here is a description of the classic Wilder's ATR:
http://stockcharts.com/education/IndicatorAnalysis/indic_ATR.html
The ATR relies on Wilder's smoothing method. This smoothing method
is very much like that of an Exponential Moving Average, because it
uses the Previous value to calculate the current value.
[ A side note, and some food for thought: In signal processing, this
is called an Infinite Impulse Response (IIR) filter, because even the
very first value in the array has an effect of the very last value in
the array, albeit, as very small effect. ]
In the example link above, they use a constant 14 periods. Our
indicator uses the exact same calcuations, except it will replace the
14 with whatever input you give for that particular bar.
Does this answer your question?
