Band Bollinger

Band Bollinger is powerful Technical Indicator developed by John Bollinger in 1980s. The essence of Band Bollinger is based on a moving average that defines the trend of the stock. Band Bollinger also provides relative boundaries of HIGHS & LOWS also called as "Bands" that can be used in rigorous trading approaches, pattern recognition & much more.


The center line is an exponential moving average; the price channels (Green & Red line) are the standard deviations of the stock being studied. The bands will expand and contract as the price action of an issue becomes volatile or becomes bound into a tight trading pattern.

Band Bollinger Calculation:

Middle band (line) = 20 days Simple moving average.

Upper Band = 20 days SMA + 20-day Standard deviation of price x 2.

Lower Band = 20 days SMA - (20-day Standard deviation of price x 2).

(Standard Deviation: Standard deviation is a mathematical formula that measures volatility)
