Fibonacci Bollinger Bands
 DarkLight
Fibonacci Bollinger Bands is an indicator that combines Bollinger Bands (BB) with the Fibonacci sequence concept, a distinct pattern of numbers used for calculation of standard deviation levels (bands). The bands (the number is customizable) deviate from Simple Moving Average (SMA) showing possible support and resistance areas or offering potential entry points.
MidLine = SMA_{n} (TP)
The band above MidLine = MidLine  σTP_{n} x F
The band below MidLine = MidLine + σTP_{n} x F
where:
SMA_{ }– Simple Moving Average for the period
_{}TP – Typical Price
F – Fibonacci number in the following sequence: 0.236, 0.382, 0.5, 0.618, 0.764
σTP_{n} – Standard Deviation over last n periods of TP
n – the number of periods
INPUTS
Input  Description 

Length  The number of periods the indicator uses to calculate the MidLine

The following data sources are available for calculation of MidLine:

Input  Description 

Multiplier  The number that Standard Deviation uses for calculation 
PLOTS
The plot renders the data you are working with on the chart. You can show/hide a plot by clicking the corresponding item in the settings. Every plot has a set of basic settings that you can change: color, weight, and type.
Plot  Description 

Plot  The middle line (SMA) 
0.236U  The upper deviation multiplied by 0.236 
0.382U  The upper deviation multiplied by 0.382 
0.5U  The upper deviation multiplied by 0.5 
0.618U  The upper deviation multiplied by 0.618 
0.764U  The upper deviation multiplied by 0.764 
1U  The uppermost band 
0.236L  The lower deviation multiplied by 0.236 
0.382L  The lower deviation multiplied by 0.382 
0.5L  The lower deviation multiplied by 0.5 
0.618L  The lower deviation multiplied by 0.618 
0.764L  The lower deviation multiplied by 0.764 
1L  The lowest band 
Color 

Click the color rectangle under the plot's name to open the palette. Use the slider at the bottom to set the opacity of the color. To create a custom color:
The customcreated colors are added to your palette. To remove a custom color, drag it out of the palette. 
Weight 
Change the value (in px) to adjust the thickness of the plot. 
Type 
The following plot types are available:
