Generally, the golden fork is a buying signal, and the dead fork is a selling signal. At the same time, it is necessary to judge whether it is short-term trading or mid-line band trading according to the combined time period of this moving average system. Pay special attention to the direction of the two moving averages after the crossing of the moving averages. If it is not evenly up or down, it is an ordinary average crossing, not a "golden fork" or a "dead fork".
