In the Bitcoin trading market, signals from candlestick patterns must be validated by confirming candles, rather than relying solely on a single candlestick. For example, the Evening Star pattern requires subsequent large bearish candles to confirm a downtrend; otherwise, it may fail. Traders should pay attention to volume coordination and market trends, and analyze support and resistance levels to avoid misjudgments due to market fluctuations. Confirmation signals at the daily level are generally more reliable. Currently, Bitcoin prices are highly volatile, and a single candlestick, such as a shadow candlestick, only provides preliminary clues. It is essential to combine subsequent trends and the market environment for a comprehensive judgment to improve the accuracy of trading decisions.
