The Idea:
I had the idea for this script when I read an article about how assets tend to revert to their long-term average or mean. The concept behind "R2" is based on the assumption that extreme deviations from the average tend to be corrected. For example, if an asset is trading well above its historical average, there is a possibility that the price will return towards the average. Conversely, if an asset is trading well below its average, there is a tendency for it to move back towards the average.
This concept serves as the foundation for this script. I have tried to keep the representation as simple as possible, and please remember that "Reversion" (as it's called in financial terms) is not a guaranteed rule but a statistical phenomenon.
The Indicator:
This indicator calculates the average and the distance of closing prices from this average every X periods. The calculated value fluctuates between 0. If the calculated value moves from above towards the zero line, it may indicate further declining prices. If the value moves from below towards the zero line, it may indicate rising prices. If the value is below the zero line, the area between the zero line and the calculated value is displayed in red. If the value is above the zero line, the area is displayed in green.
You can adjust the number of periods. The 'Multiplier' allows you to set how sensitive the indicator reacts, and the 'Threshold' variable sets the threshold for calculating a new average. It's best to adjust the settings to find the most suitable configuration for your needs.
