Dark Cloud Cover candle pattern which is bearish so far today.
Dark Cloud Cover is a candlestick pattern that shows a shift in momentum to the downside following a price rise. The pattern is composed of a bearish candle that higher than the previous session but then closes below the midpoint of the prior bullish candle.
