Source Code

Overview
Moving Averages Trends and Filters implements FIR functions including ALMA using Gaussian weights, BLMA with Blackman window, and BWMA using Bessel function, along with IIR moving averages from mihakralj's library. The main settings allow adjustment of period and source. These moving averages are plotted as trend filters and filters on the price chart. It draws multiple lines for different smoothing options. There are no trade signals or position sizing, as it is a utility library for trend analysis. The functions calculate from available bars and handle edge cases with runtime errors for invalid parameters.
