The word marubozu means “bald head” in Japanese, and this is reflected in the candlestick’s lack of wicks. The Black Marubozu is a one day bearish pattern. Here the open is equal to the day high and the close is equal to the day low. It is a long black (down, or red on the charts) candle, with little to zero upper or lower shadows. The pattern shows that sellers controlled the trading day from open to close.
