In this article, we will show For exchange rates, Bollinger Bands have a weakness for financial series that have a fat tail or leptokurtic distributions. A study found that using an adjusted Bollinger band takes into account these distributions and volatility clustering and can perform much better in … It is assumed that: -- Bollinger Bands are desired at 2 standard deviation's from the mean. -- moving average used is a simple moving average """ self.check_bars_type(bars) upperband, middleband, lowerband = ta.BBANDS( close, timeperiod=period, nbdevup=2, nbdevdn=2, matype=0) return upperband, middleband, lowerband

Bollinger Bands encapsulate the price movement of a stock. It provides relative boundaries of highs and lows. The crux of the Bollinger Band indicator is based on a moving average that defines the intermediate-term "trend" based on the time frame you are viewing. This trend indicator is known as the middle band.

The orange line is your data, the green line is the upper "bollinger" band, the blue line is the lower "bollinger" band. The red dots indicate where your data is either above or below the bands.

Bollinger BandWidth is an indicator that derives from Bollinger Bands, and measures the percentage difference between the upper band and the lower band. BandWidth decreases as Bollinger Bands narrow and increases as Bollinger Bands widen. Because Bollinger Bands are based on the standard deviation, falling BandWidth reflects decreasing Nov 27, 2013 · This video teaches you how to calculate Bollinger Bands (R) in python.
