First, the longer the macd red bar, the greater the distance between the short-term moving average and the long-term moving average, which means that the stock price has risen sharply. At this time, the stock price may start to fall, so it should be mainly sold.
Second, the two lines of macd are glued together on the 0 axis. In general, the short-term moving average goes down through the long-term moving average, which is called the dead fork. It is a sell signal, indicating that the bulls have ended, and then it should be a short-term trend. However, there are also cases where the short-term moving average wears the long-term moving average, indicating that this is a strong stock.
Third, the two lines of macd are bonded together under the 0 axis, which means the opposite sides are bonded on the 0 axis.
