Description:
Moving Average Ribbon
Formula Parameters:
Base Length: 10
Arithmetic Or Geometric 1 Or 2: 1
Increment Or Multiplier: 10
Line Thickness: 2
Display Title Value: False
Notes:
Plots a "Moving Average Ribbon" using the gradient color system ╓ it
is created using a series of exponential moving averages of various
lengths. The lengths of the averages are calculated based on the length
of the first moving average line which is set by the input BaseLength.
Each subsequent length is calculated based on the ArithOrGeom_1or2 input.
