Doji, spinning top, and marubozu

Under the course rule, what makes a doji a dragonfly doji?

• A long upper wick
• An upper wick of 10% of the range or less, so the tiny body sits at the top
• A body of exactly zero

A marubozu closes at its high after a long rise. What does the name itself tell you about the next bar?

• It will rise too, because buyers are strong
• It will fall, because the move is exhausted
• Nothing: the name describes this bar only
