A Heikin Ashi Candle Without Wick has no upper shadow. Heikin Ashi candles average the open, high, low and close of each bar with the previous candle, which filters out noise and makes trends easier to see. A red Heikin Ashi candle with no upper shadow is a classic sign of strong selling pressure in a downtrend, because the price never traded above the smoothed open during the bar.
