Overview
Savitzky-Golay Moving Average (SGMA) plots the result as an overlay on the price chart. The main settings are the lookback period (window size) and polynomial degree. The filter applies weighted coefficients to preserve signal features while smoothing the chosen source like close. It draws directly on the chart without a separate pane.
