bollinger bands ® technical indicator (bb) is similar to envelopes, but with a key difference in how the bands are calculated. while envelopes plot bands a fixed percentage away from the moving average, bollinger bands use standard deviations to adjust the band width based on market volatility.Also recommended: B Bands Psar Indicator - similar indicator with strong performance on MetaTrader 5.
this indicator is designed to adapt to market conditions. when volatility increases, the bands widen, and during calmer periods, they contract.
bollinger bands can be applied to price charts or indicator charts. the interpretation is based on the tendency of prices to stay within the upper and lower bands. the variable width of the bands is a unique feature, reflecting the volatility of prices.
here are some key characteristics:
- price breakouts often occur after a period of low volatility, causing the bands to contract.
- if prices break through the upper band, it suggests a continuation of the current trend.
- when price spikes outside the band are followed by spikes inside the band, a trend reversal may be imminent.
- price movements starting from one band line often reach the opposite line.
the bollinger band indicator consists of three lines:
- middle line (ml): a simple moving average of closing prices over n periods.
- top line (tl): the middle line plus a multiple of standard deviation (d).
- bottom line (bl): the middle line minus the same multiple of standard deviation.
the standard deviation (stddev) is calculated as the square root of the sum of squared differences between closing prices and the simple moving average, divided by the number of periods.
it is recommended to use a 20-period simple moving average as the middle line and set the top and bottom lines two standard deviations away. moving averages with fewer than 10 periods may not be as effective.
