If the upper shadow of the red candle is longer than its lower shadow and the upper shadow of the green candle is longer than its lower shadow, it indicates that the upper and lower wicks of the red and green candles are equal. In this case, it means that the price does not show a clear trend in a specific direction, and the price movement is neutral. This situation usually suggests market uncertainty or that the price is moving within a horizontal range.
