Doji-s and What they mean

1. Dragonfly 

It gives a buy signal when the the doji, high is broken on the next candlestick.

2. Gravestone

It’s a bearish Doji.  If the market is in an uptrend and if you notice a Gravestone Doji candlestick, it may be the first indication that the trend may start to reverse to a downtrend.

3. Four price

This means that the price did not change at all during the period of a candlestick.

It’s common to see the Four-Price Doji in markets where trading volume and liquidity is extremely low.

If you see many Four-Price Dojis on the chart – stay out of this market.

Because liquidity is so low, you won’t be able to get in and out of your trades easily.
