ATRanger uses Average True Range plus a variety of Moving Averages of the ATR in band format.
This is another way to identify overbought and oversold (poking out of the bands, or bouncing from them as support or resistance.)
A variety of Time-Frames can be selected, as well as several Moving Average Types to draw the bands with. (SMA, WMA, VWMA, SMMA, HMA, EMA)
