This is a Pine Script for the "Cumulative Weighted Exponential Moving Average" (CWEMA) indicator. The script defines the CWEMA indicator using the ema() and wma() functions, which respectively calculate the exponential moving average and weighted moving average of a given data series. The cwema() function computes the weights for each value in the moving average and then uses the wma() function to calculate the weighted moving average of the exponentially weighted moving average of the input data series. The resulting CWEMA values are plotted on a chart.
