In this example, we have used the default settings of 20-period MA, +2 standard deviation for the upper band, and -2 standard deviation for the lower band. On a regular trading day, the price of a currency pair fluctuates. So, we can use the concept of standard deviation from the MA to determine if the price of a currency pair is low or high. Bollinger BandWidth can be found in the indicator list on SharpCharts. The default parameters (20,2) are based on the default parameters for Bollinger Bands. These can be changed accordingly. 20 represents the simple moving average. 2 represents the number of standard deviations for the upper and lower band. Values: numerical (recommended: between 1.9 and 2.1) - represents a multiplier value used in the bollinger bands calculation. Default value: 2 Bollinger Bands Parameters As I mentioned above, the default is to use the 20 period simple moving average. The upper band is then placed 2 standard deviations above the 20 MA and the lower band is placed 2 standard deviations below. May 07, 2020 · BOLU = MA (TP, n) + m ∗ σ [TP, n] BOLD = MA (TP, n) − m ∗ σ [TP, n] where: BOLU = Upper Bollinger Band BOLD = Lower Bollinger Band MA = Moving average TP (typical price) = (High + Low Bear in mind that when you use the Bollinger Band theory, it only works as a gauge or guide, and should be use with other indicators. Normally, we use the 20-Day simple moving average and its standard deviations to create Bollinger Bands. Strategies some investors use include shorter- or longer-term Bollinger Bands depending on their needs.
Upon selecting Bollinger Bands, the default setting will appear in the parameters window (20,2). The first number (20) sets the periods for the simple moving

Return value of the Upper Bollinger band technical indicator. Syntax: BollingerUp (price) Example: //last bar piercing the upper Bollinger Bands. This instruction use the default parameter of a Bollinger band = 2 deviations from the mean. The Bollinger Bands function was developed by John Bollinger. and BOLLINGERLOWER functions require the following parameters: Default value is 2. 31 Mar 2018 This trend indicator is known as the middle band. Most stock charting applications use a 20-period moving average for the default settings. The the daily Bollinger band system stays robust during parameter changes in a For all the performed tests exactly the same parameters (default) were taken in
Other traders buy when price breaks above the upper Bollinger band the default parameters if the data were normally distributed, one will typically find less;
A recent study examined the application of Bollinger Band trading strategies combined with the ADX for Equity Market indices with similar results. In 2012, Butler et al. published an approach to fitting the parameters of Bollinger Bands using particle swarm optimization method. The Bollinger Bands® consist of three bands, which revolve around a centred simple moving average (SMA), with the default value of 20, of which 85% of the time, the price is held within the following default boundaries: Lower band – SMA (minus two standard deviations) Upper band – SMA (plus two standard deviations) Trade With Admiral Markets

The default parameters, 20 periods and two standard deviations, may be adjusted to suit your purposes: Middle Bollinger Band = 20-period simple Moving Instead of using the default parameter settings, the authors use a computer algorithm to optimize the parameters of Bollinger Bands. Leung and Chong ( 2003) find The default parameters of 20 periods for the moving average and standard deviation calculations, and two standard deviations for the width of the bands are just
