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 average and the standard deviation. The Get rollinger bands function gets its variables from the user: get_bollinger_bands(rm, rstd): upper_band = rm + (rstd * 2) lower_band = rm - (rstd * 2) return upper_band, lower_band The only variables used are the ones between the parentheses after the function name. This means they are to be imputted by the user. The Bollinger bands themselves are, as you may know, popularised by John Bollinger.

‘bands’ will draw standard Bollinger Bands, ‘percent’ will draw Bollinger %b and ‘width’ will draw Bolinger Bands Width. The last two will be drawn in new figure regions. See bollingerBands in TTR for specific details as to implementation and references. Value. Bollinger Bands will be drawn, or scheduled to be drawn, on the current

Bollinger Band® Width plots in a separate pane below the chart, whereas Bollinger Bands® plot as an overlay to the chart.

The standard deviation of closing prices for a period equal to the moving average employed is used to determine the band The plot_ly() function has numerous arguments that are unique to the R package (e.g., color, stroke, span, symbol, linetype, etc) and make it easier to encode data variables (e.g., diamond clarity) as visual properties (e.g., color). By default, these arguments map values of a data variable to a visual range defined by the plural form of the Bollinger BandWidth is an indicator derived from Bollinger Bands. In his book, Bollinger on Bollinger Bands, John Bollinger refers to Bollinger BandWidth as one of two indicators that can be derived from Bollinger Bands (the other being %B).
