D2MA

The script is called "D2MA" (Distance to Moving Average). It calculates the distance between the closing price and a user-selected type of moving average (MA). It also plots this distance on a chart, allowing users to see how far the price is from the chosen moving average. Users can choose to display this distance as either an absolute value or as a percentage.

Input Parameters

• Length (len): The number of bars (or periods) used to calculate the moving average.
  
• Source (src): The price data used for calculations, typically the closing price.
  
• Percentage Distance (pc): A boolean option to display the distance as a percentage instead of an absolute value.
  MA Type (maType): The type of moving average to use.
  

1. Simple Moving Average (SMA)
   
2. Exponential Moving Average (EMA)
   
3. Hull Moving Average (HMA)
   
4. Arnaud Legoux Moving Average (ALMA)
   
5. Triple Exponential Moving Average (T3)
   
6. Power Weighted Moving Average (PWMA)
   

The script includes functions to calculate different types of moving averages:

The difference between the source price (e.g., closing price) and the calculated moving average. if Distance as Percentage, the distance expressed as a percentage of the moving average value.
Plotting the Data

Signal Line: The signal line changes colour (green or red) based on whether the distance is increasing or decreasing.

How to Use

1. Identify Trends: By seeing how far the price is from a selected moving average, traders can gauge the strength of a trend.
   
2. Spot Reversals: Significant deviations from the moving average can signal potential reversals.
