Tutorial 98 applied to a daily GBPUSD chart with a ‘squeeze’ length of 120. The ‘squeezes’ are shown where the upper and lower Bollinger bands are plotted black and a little thicker.

A narrowing of the Bollinger bands is an indication of lower volatility. According to John Bollinger (who created the Bollinger band concept), periods of low volatility are often followed by periods of high volatility. This could mean that a narrowing of the Bollinger bands (or a period of low volatility) –a ‘squeeze’–may foreshadow a period of higher volatility, or a breakout in price.

Tutorial 98 demonstrates how to calculate and plot the Bollinger bands, as well as to calculate when the bands narrow to the point when the difference between the high Bollinger band and the low Bollinger band is the lowest in a user input number of bars.
