To determine whether a candlestick is bullish or bearish, it is actually to see which one is more convincing, the entity or the upper and lower shadow lines. The principle is: when the bulls are dominant, the bullish candlestick is full and the closing is close to a high level; When the bears are dominant, the bearish entity is solid and closes at a low level. The appearance of long upper and lower shadow lines or cross stars usually indicates a long short tug of war, neutral market sentiment, and unclear direction. This candlestick pattern represents active funds hesitating and the market lacks continuity, making it unsuitable for aggressive operations. For example, the Bitcoin candlestick on June 15, 2025, is a typical long short equilibrium signal. The vast majority of novice traders tend to go to two extremes when understanding candlesticks: one is to use a single candlestick to judge trends, ignoring position, structure, and background; Another type is that the foundation is not solid, and even if the signal is clear, they dare not take action.
