The Doji candlestick, also known as the Doji star, is a distinctive candle pattern that shows hesitation and weakening momentum of a trend in the market. When a Forex currency pair opens and closes at the same level, a Doji is formed.
The vertical lines above and below the horizontal line are simply extended farther in the Long-Legged Doji. This means that the price action of the candle moved substantially up and down during the span of the candle but that it closed at about the same level as it opened.
The Dragonfly Doji can emerge at the peak or bottom of a trend and indicates the possibility of a shift in direction. Prices did not increase over the beginning price since there is no line above the horizontal bar, forming a ‘T.’
