The core of trend retracement trading is to find positions and signals under the premise that a trend has already been established, allowing for smaller entry risks and higher tolerance for errors. Support and resistance switching occurs when breaking through previous highs and then confirming support on a pullback; a stable footing indicates that buyers are willing to take over at higher levels. The Fibonacci 0.618 level is the last defensive position for bullish trends; if a doji appears here, it indicates that the bearish test has failed and the bulls regain dominance. When the EMA moving average retraces, if the price tests and does not break through the key moving average, it becomes one of the conditions for following the trend. Regardless of the method, the most important thing is to establish the trend and direction first; otherwise, the practical results will be significantly discounted.
