Methods Explanation

These four Methods of using Bollinger Bands illustrate four different philosophical approaches to the market and the techniques of John Bollinger. Detailed explanations for each Method are available on the METHODS section of main menu.

Volatility Breakout (Method I)

Method I - Volatility Breakout - also known as The Squeeze, anticipates high volatility, taking advantage of the cyclical nature of volatility. Low volatility begets high volatility, so we provide lists of stocks with extremely low volatility anticipating that an expansion of volatility may follow.

Perhaps the most elegant direct application of Bollinger Bands is a volatility breakout system. These systems have been around a long time and exist in many varieties and form. The earliest breakout systems used simple averages of the highs and lows, often shifted up or down a bit. As time went on average true range was frequently a factor.

Trend Following (Method II)

Method II - Trend Following - relies upon the idea that strong price action accompanied by strong indicator action is a good thing. It is a confirmation approach that waits for these two conditions to be met before giving an entry signal. Of course, the opposite, weakness confirmed by weak indicators, generates a sell signal. In essence, this is a variation on Method I, with an indicator, MFI, being used for confirmation and no requirement for a Squeeze. This method may anticipate some Method I signals.

Reversal (Method III)

Method III - Reversals - anticipates the reversals by comparing the contacts with the bands (tags) and the indicator of price trend.

What we are doing with Method III is clarifying tops and bottoms by involving an independent variable, volume, via the use of volume indicators to help get a better picture of the shifting nature of supply and demand.

Confirmed Breakouts (Method IV)

Method IV , like Method I, is based on volatility breakout

Method IV compares the actual value and the high and low of the previous bar and then takes a position at the breakout.
