A shooting star pattern at the top of an uptrend is a bearish reversal candlestick with a small body near the day’s low, little or no lower shadow, and a long upper shadow. It shows that buyers pushed the price higher during the session, but sellers regained control and forced the close near the opening price. When this pattern forms at resistance or after a strong rally, it signals weakening bullish momentum and a potential reversal to the downside, especially if confirmed by a bearish candle in the next session.
