Big pie: Yesterday evening, the price strongly inserted the pin downward to test the position of the four-hour lower rail area. It failed to achieve an effective breakthrough and bottomed out. At present, the price has shown a continuous positive trend in the four-hour level, and the short position can be in a state of virtual shrinkage. In the continuation, the circuitous rise of the moving average is fully apparent. The overall market rhythm is bullish. At the short-term level, the price has continuously stretched and broken through the middle track. Although there is a slight retracement at present, it does not affect the subsequent upward recovery of the price. In the short term, we will first treat it with a shock mentality. The tentative range is 68600-71000. The overall shock range is also relatively large. At the same time, the shock amplitude is not expected to be too large at the weekend time point.
