Not all high-position candlesticks can reverse the market; only structural overlaps (i.e., "acceleration + reversal") are worth betting on.
Taking the following chart as an example, after a rapid price surge, the appearance of a Evening Star indicates that the upward momentum is exhausted, a point of bullish to bearish transition is formed, and the RSI simultaneously enters the overbought zone, further reinforcing the "bullish exhaustion" signal.
