Bollinger Bands are envelopes plotted at a standard deviation level above and below a simple moving average of the price. Because the distance of the bands is based on standard deviation, they adjust to volatility swings in the underlying price
Bollinger bands help determine whether prices are high or low on a relative basis. They are used in pairs, both upper and lower bands and in conjunction with a moving average.
Bollinger bands take the form of three lines: The middle line is a moving average of the given market. An upper band, which is two standard deviations above the MA. A lower band, which is two standard deviations below the MA.
Bollinger Bands are among the most reliable and potent trading indicators traders can choose from. They can be used to read the trend strength, to time entries during ranging markets and to find potential market tops.
