Please visit the original open source author script : Kaspapero "This indicator, called RainbowChart, displays the Fair Value and multiple colored bands based on Fibonacci levels.
Key Features:
Fair Value: A central line that represents the fair value of the asset. The Fair Value is calculated using a regression model with two parameters: ln(a) and b. These parameters can be adjusted to fine-tune the model according to your needs.
Colored Bands: Eight colored bands calculated as multiples of the Fair Value. Each band's visibility can be toggled on or off according to user preferences. Additionally, four customizable bands are available (disabled by default), allowing users to modify their multiplicative factors and colors for enhanced personalization."
