A break out of the bands generally occurs when the stock price moves higher than the upper band or stock price moves lower than the lower BB driven by some event. The favorable news on STEC was an example of such an event.

A median line is generally shown in the center between the 2 bands representing the moving average of the stock price. The bands are formed by adding and subtracting two standard deviation calculations of price from the moving average of the stock. Prices are relatively high when close to or above the upper band and relatively low when at or below the lower Bollinger Band. Although the bands formed are statistically based, they are not considered statistically rigorous. Statistically the time periods are too short and stock prices do not have normal distributions.

The Bollinger Band Width makes it easier to visually identify new highs and lows. It is defined by alternating phases of volatility compression and expansion.

What are the best indicators to use in conjunction with Bollinger Bands?

When this range of Bollinger Bands is tight, it is said to be in a squeeze. When this range is wide, we can expect the market to be very volatile.

• Narrow bands indicate a squeeze, which means that volatility is low.
• And if the is price near the lower Bollinger Band, it’s considered “cheap” because it’s 2 standard deviation below the average.
• The key nuance in setting up Bollinger Bands is maintaining the optimal ratio between the period of the moving average and the number of standard deviations.
• Click the duration settings button, Eg ‘Daily 6 Months’ directly above the Charts to change the chart Duration or Period.
• A range is created when the price keeps going up and down inside the same region, creating a level of support below, and a level of resistance above.

A double bottom occurs when there is a fall in price, followed by a rise, followed by another fall that is close to the previous low, and finally another rise.

Using the BandWidth Indicator

The Bollinger Bands is a technical analysis tool that works on the basis of a moving average. The lag rate is calculated using the standard deviation multiplied by the specified factor. For example, for the MA with a period of 21 bars, it is recommended to use 2 standard deviations, and for one with a period of 10 bars – 1.9. The well-known trading analyst Wilfrid LeDoux used a trading channel based on two moving averages as technical indicators in his trading system. The first band was built based on the highs, and the second – on the lows.

Aside from how the bands/channels are created, the interpretation of these indicators is generally the same. A trader can visually identify when the price of an asset is consolidating because the upper and lower bands get closer together. After a period of consolidation, the price often makes a larger move in either direction, ideally on high volume.
