Overview

EMA High/Low/Median Ribbon displays HMA 9, EMA 16, HMA 21, EMA 34 and EMA 50 lines with separate bullish and bearish colors plus optional band fills for each. Users toggle visibility of lines and fills while adjusting offset widths. The script draws directly on the price chart without a separate pane and provides color coded trend visualization.
