Dark Cloud Cover
Dark Cloud Cover is a two-candle bearish reversal pattern where a large bullish candle is followed by a bearish candle that opens above the prior close and then closes well into — at least halfway through — the body of the prior bullish candle, historically observed at price highs as a sign of potential reversal.
The Dark Cloud Cover drew its name from the meteorological image of a dark cloud rolling over a sunny sky — an uptrend represented as clear skies, with the bearish second candle representing the sudden appearance of threatening clouds. The two-candle structure told a specific story: buyers had a strong session on the first candle, then on the second session the market opened even higher (gap above the prior close), initially extending the bullish momentum, but sellers then overwhelmed the advance and drove price down to close deep into the first candle's bullish body.
The requirement that the second candle close at or below the midpoint of the first candle's body was the defining criterion that distinguished a Dark Cloud Cover from a less significant bearish close after a bullish day. A close in only the upper quarter of the first candle's body implied modest selling; a close below the midpoint (and ideally toward the lower third) implied that sellers had made substantial progress reclaiming the ground that buyers had taken the prior session. The deeper the penetration, the more significant the pattern was historically considered.
On Indian equity charts, Dark Cloud Cover formations were noted in individual large-cap stocks following sharp earnings-driven rallies. When a Nifty 50 or Nifty Next 50 stock surged on strong quarterly results, and the subsequent session opened higher (perhaps driven by continued analyst upgrades) but then attracted significant selling and closed well below the prior session's open, the resulting two-candle sequence matched the Dark Cloud Cover template. Traders and analysts watching such stocks noted the pattern as evidence that the post-results enthusiasm had met meaningful supply at higher prices.
The gap between the first candle's close and the second candle's open was considered an important feature. A small gap or no gap reduced the visual impact and analytical significance of the pattern, as it suggested less dramatic bullish conviction at the open of the second session. A wider gap that was nearly fully filled by the close strengthened the interpretation, as it highlighted the dramatic intraday reversal from peak optimism to renewed concern.
The Dark Cloud Cover was distinguished from the full Bearish Engulfing Pattern by the second candle's inability to close below the first candle's open. If the second candle closed below the first candle's open rather than merely below its midpoint, the pattern upgraded to a Bearish Engulfing, which was considered more decisive. The Dark Cloud Cover therefore occupied an intermediate level of bearish severity — more significant than a simple bearish close after a bullish day, but less extreme than the full engulfing of the prior session's gains.
