2. Short-term trading K-line cycle selection: An efficiency rule that beginners must watch
High-frequency trading focuses on the 5-minute K-line to capture instantaneous fluctuations, combined with 15-30 minute cycles to confirm trends and avoid being misled by noise; ordinary short-term players directly use the 30-minute cycle as the core period, combined with daily lines to determine the overall direction. Remember: during pullbacks, if the 5-minute K-line retraces without breaking the 10-day moving average, and the 30-minute MACD shows a golden cross, it is an entry signal with a win rate exceeding 60%. $BTC
