A Heikin Ashi Candle Without Tail has no lower 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 green Heikin Ashi candle with no lower shadow is a classic sign of strong buying pressure in an uptrend, because the price never traded below the smoothed open during the bar.
