A Heikin Ashi New Green Candle is the first green candle after one or more red ones. 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. Because Heikin Ashi colors change only when the averaged price turns, a new green candle is a smoothed signal that a decline may be ending and an upswing starting.
