A bullish formation, White Marubozu is formed when price action suggests that the bulls have dominated the trade from start to the end of session. Since the bulls have dominated the whole trading day, there is a high probability that in the short-term, further upward movement might be witnessed at the counter.
Appearance of White Marubozu after a long phase of southward or sideways movement should alert a trader and that particular stock should be brought up on the trading screen for a possible long trade.
