The white opening marubozu is a single candlestick pattern with a long white body, an upper shadow and the lack of lower shadow.
The day opens and prices rise above the opening price. Prices continue to move up all day thus forming the long white body. The closing price is above the opening price but not at the high of the day that creates the upper shadow.
