Generally speaking, three trading cycles are enough, and their relationship is 1: 5. For example, when trading with a daily chart, the upper layer of the daily chart is a weekly chart and the lower layer is a 1 hour chart. If only MACD is used as the market judgment before trading, the usual method is to judge the one-way direction by looking at the position of MACD relative to the zero axis on the weekly chart, such as 1. The weekly chart is bullish on the zero line, indicating that the market has started at that time, and it is unlikely to find the entry signal on the daily line, so it is necessary to find the entry signal in the hourly chart; 2. Above the zero axis, but the double line is downward, it is judged as an adjustment in the bull market. In this case, look for the entry signal on the daily chart, including the golden fork and deviation; 3. If MACD frequently crosses the zero axis up and down near the zero axis, it is judged as a volatile market and leaves the market to wait and see. or vice versa, Dallas to the auditorium
