The opening black marubozu is an inverted version of the closing black marubozu. Price opens at the high for the day and then pluummets, recovering like a patient finding strenght before death and leaving a lower shadow behind.
The psychology behind the pattern tells little since we are dealing with a single candle lin, but the bears rule the day. Price begins heading down after the open, forming a tall black candle. Sometimes during the day, the bulls make an appearance and force price up from the day's low, keeping the bears on their toes until the close. A slight majority of the time and trend will continue lower in succeeding days, but with a continuations rate of just 52%, expert a random direction outcome.
An example of that comes from the middle
marubozu candle. Price is trending upward when the
opening black marubozu appears. A long white candle froms that suggest a strong upward thrust, but the
opening black marubozu the next day seems to say, "Not so fast!" It tries to push price down. The stock stalls for another day while the bulls and bears duke it out, but the uptrend soon resumes.
