Overview
Calculated colors ranks the moving average with percentrank over 100 bars and converts that rank into plot transparency, capped at 80, so the moving-average line fades as the rank falls. The close is drawn in a fixed color. Two color inputs set the base colors for the moving average and the close. It does not generate trade signals or manage risk.
