Kirshenbaum Bands are similar to Bollinger Bands, in that they measure market volatility. However, rather than use Standard Deviation of a moving average for band with, they use Standard Error of linear regression lines of the Close. This has the effect of measuring volatility around the current trend, instead of measuring volatility for changes in trend.
Paul Kirshenbaum, a money manager and mathematician with PhD in economics from NYU, submitted this rather unique trading band which is "de-trended".
