The script is a technical analysis indicator that calculates a weighted moving average of a given data series. The weighted moving average is calculated using a custom weighting scheme that adjusts the weights based on the volatility of the market, as measured by the average true range (ATR) indicator. The resulting weighted moving average is smoothed using a Gaussian moving average, and the resulting smoothed moving average is plotted on the chart. To use this script, the user can customize several input parameters, including the length of the moving average, the primary and secondary weights to use in the custom weighting scheme, the ATR length, and the smoothing parameter for the Gaussian moving average. With these inputs, the script calculates and plots the weighted moving average on the chart, allowing the user to analyze the trend and behavior of the data series using a custom weighted moving average.
