The overall trend this year cannot be said to be similar to the trend in 2019, it is exactly the same. At the end of December last year, I publicly said that I was optimistic about the market situation from January to June in the first half of this year. June and July were the turning points. Generally speaking, there are two types of upward trends, three major waves and five major waves. At present, I personally prefer the former. If the pie can fall below 28,000 in July, and the rebound high is no more than 31,000, then 31,500 should be the top of the pie in the past year. In terms of operation, I have been holding short orders recently. From around bnb285, I told my friends that the trend was to short bnb and roll the position to 120-150. Now the monthly line of bnb has reached the high point of the upper shadow line of 257. I personally plan to act as planned, with a stop loss of 260 and a target of 150.
