Overview
Smoothed Heikin Ashi Signals derives synthetic Heikin Ashi values and applies multi-layered exponential and triple exponential moving average smoothing filters to both price streams. Signals are triggered when the smoothed price crosses above or below the smoothed Heikin Ashi line, filtered to ensure alternating signals. Triangle markers plot directly on the price chart to indicate long and short conditions. A single input controls the smoothing length.
