One Black Crow

This reversal pattern starts with a green candle in an uptrend, followed by a gap down, with sellers maintaining control and closing below the green candle's open.

This pattern is significant for a few reasons. The initial gap down indicates a strong and sudden change in sentiment from the previous candle.

Price pushing lower throughout the day and closing below the previous day's open is additional confirmation (combined with the gap down) that the trend may be reversing.
