DEnvelope [Better Bollinger Bands]*** ***
Bollinger Bands (BB) usually expand quickly after a volatility increase but contract more slowly as volatility declines. This extended time it takes for BB to contract after a volatility drop can make trading some instruments using BB alone difficult or less profitable.
In the October 1998 issue of "Futures" there is an article written by Dennis McNicholl called "Better Bollinger Bands", in which the author recommends improving BB by modifying:
- the center line formula &
- different equations for calculating the bands.
These bands, called "DEnvelope", follow price more closely and respond faster to changes in volatility with these modifications.

BBImpulse IndicatorBBImpulse is part of the latest indicators package offered by John Bollinger. Excerpt from their market blurb (www.bbforex.com):
"BBImpulse is derived from %b. Its value is the periodic change of %b, so if %b was 0.45 this period and 0.20 last period the present value of BBImpulse is 0.25. We present two reference levels on the chart, an alert level and an impulse level."
"Generally the market moves in the direction of the latest alerts and/or impulses except towards the end of a move where one can take advantage of exhaustion/reversal signals from this indicator."
"Ian Woodward employs BBImpulse for his Kahuna signals using key levels of 0.24 and 0.40."
I added support for the following:
- Highlighting alert/impulse trigger bars
- Rendering the range (check options page).
I noticed that the range, by itself, highlights lot of info:
- Tapering in (narrowing) of range may signify topping or falling prices.
- Tapering out (expanding) may signify nearing a bottom or rising prices.
- Range getting "ranged" between alert or impulse levels signify a major move in the direction of the last impulse trigger. I think for this, alert level ranging intensity is greater than impulse level ranging intensity.
Someone more familiar with BB will have more observations, I am sure. Please do share here so we BB noobs can learn :)

Acceleration BandsPrice Headley\'s Acceleration Bands serve as a trading envelope that factor in a stock\'s typical volatility over standard settings of 20 or 80 bars. They can be used across any time frame, though Headley prefers to use them most across weekly and monthly timeframes as breakout indicators outside these bands, while using the shorter time frames to define likely support and resistance levels at the lower and upper Acceleration Bands. Acceleration Bands are plotted around a simple moving average as the midpoint, and the upper and lower bands are of equal distance from this midpoint.

Indicator: Price Headley Accelaration Bands [LazyBear]The Acceleration Band System was published in "Big Trends in Trading" by Price Headley in 2002. The system designed to catch stocks as they start to trend but before they go parabolic. The system is simple but supposed to be very effective.
This system makes use of %R and ADX a lot to determine the entries/exits. Refer to the documents listed below for the complete set of rules.

Indicators: Hurst Bands and Hurst OscillatorThese 2 indicators are derivative work from Jim Hurst's book - "The Magic of Stock Transaction Timing".
The bands are % bands around a median that gets calculated according to Hurst's formula. The outer bands (called ExtremeBands) signify extreme overbought/oversold conditions. Inner bands signify potential pullback points. As you can see, they also act as dynamic S/R levels.
The oscillator bands match the bands overlaid on price, so you will get an excellent indication of where the price is gonna do by using the oscillator along with the bands. Note that Hurst Oscillator can be used separately too, there is no technical dependency on Hurst Bands.
