The White Marubozu is a single candlestick pattern characterized with a long white body having no shadows on either end. It is an extremely strong bullish candlestick pattern.

Recognition Criteria:

1. A white Marubozu does not have upper or lower shadows.
2. The day opens and prices continue to go up all day thus forming a long white day with no lower shadow.
3. The day also closes at the high of the day and hence with no upper shadow.

A White Marubozu simply means that the opening price is equal to the low price of the day and the closing price is equal to the high price of the day. This shows that the buyers controlled the price action from the first trade to the last trade. In a White Marubozu day, the day opens and prices continue to rally up all day long without looking back. The bulls were very strong during the day at such a degree that it caused some concern among the bears and led them to cover their short positions thus adding fuel to the rally.

Important Factors:

What the White Marubozu says about the future course of the trend depends a lot on the general picture. A White Marubozu can possibly be the first part of a bullish continuation pattern but it may also be interpreted as a bearish reversal candlestick pattern depending on the preceding day's candlesticks.

The White Marubozu is a single candlestick pattern and consequently it has low reliability. It reflects only one day's trading and it may show the continuation of the trend but also may indicate reversal. It needs to be used with other candlesticks for a better and healthier judgment about the status of the trend.
