After a sharp dive, the pie and ether experienced a rapid correction at midnight. The pie dropped as low as 68,600, while ether touched the 3,831 line. In the early morning, bulls began to rebound and regain some of their lost ground. The price of the big pie currency rebounded to a maximum of 71,770, and Ether rebounded to a line of 3,995, but then ushered in another wave of slight retracement. The daily level shows a negative cross closing line, which is a big impact for the bulls who have been rising in the past few days. In a strong market, adjustments and corrections are normal phenomena, but continuous sharp declines are what bulls do not want to see. Therefore, it is difficult for the market price to maintain a strong unilateral rhythm in a short period of time, and the space for downward retracement is expected to expand. In this case, we need to adjust our unilateral multi-strategy. In addition to continuing to push back to get long, we can also appropriately participate in short operations. The appearance of a negative line is seen as a downward correction by bulls, rather than a change in trend. A small-cycle correction will not change the final upward trend. The current high is not the top of the market, and there is a higher position. After the adjustment is completed, the market is expected to continue to break high and continue. It is recommended to go short first and then participate in long positions during the day, paying special attention to the short pressure in the 72200-72500 area of the market, with a target of 71000-70000; when Ether is near 4050-4040, consider opening a short position, with a target of 3950-3900.
