[JL] n Bars Average True Range

I just want to use 1-hour ATR on a 5-min chart, but I don't want to use the security function to get 1-hour ATR.

I don't know if there is a similar script but I decided to change a little from the original ATR source code.

Just change tr function to n_true_range function:

• math.max(ta.highest(high,n) - ta.lowest(low,n), math.max(math.abs(ta.highest(high,n) - close), math.abs(ta.lowest(low,n) - close)))
  

Here is the comparison image from a 5-min chart with the nATR and a 1-hour chart with the original ATR.
