Theory :

The Kirshenbaum Bands were authored by Paul Kirshenbaum. Their range is based on standard error as calculated from a hypothetical linear regression line. This range is added to and subtracted from an exponential moving average of the price to produce a top and a bottom band. 

As a deviation from the original, you can chose one of the 4 types of average to sue instead of using just EMA. Averages that can be used are :

• simple moving average
• exponential moving average
• smoothed moving average
• linear weighted moving average

Usage :

It can be used in a similar way as Bollinger bands
