A doji pattern signifies that no one is winning the tug of war between supply and demand. In an   uptrend this  means that the bulls have won previous battles. Now the latest skirmish's outcome is uncertain. In a downtrend the bears have won, forcing prices down. Now that bulls are buying, the tide may be turning.

1) Doji Star

A “long-legged” doji   is a far more dramatic candle. It says that prices moved far higher on the day, but then profit taking kicked in. Typically, a very large upper shadow is left. A close below the midpoint of the candle shows a lot of weakness

2) Long-legged Doji 

A “gravestone doji”  as the name implies, is probably the most ominous candle of all, on that day, price rallied, but could not stand the altitude they achieved. By the end of the day. They came back and closed at the same level. 

3) Gravestone doji 

A “Dragonfly” doji depicts a day on which prices opened  high, sold off, and then returned to the opening  price.  Dragonflies  are  fairly  infrequent.  When  they  do  occur,  however,  they  often  resolve bullishly (provided the stock is not already overbought as show by Bollinger bands and indicators such as stochastic). 

4) Dragonfly doji 

What doji tells us ? Bullish traders push prices up, while bearish traders reject the higher price and push it back down. Also, bearish traders may try to lower prices, while bulls fight back and raise prices.

A Doji candlestick is a neutral indicator that gives little information. A Doji is also not commonly formed, making it unreliable for detecting price reversals.. When it happens, it isn't always reliable. The price may not move in the expected direction after the confirmation candle.
