Is the market so weak? It rebounded to 88,500 in the morning and then fell back. It just reached 87,100. It was really crazy when it was pulled up. It soared up all of a sudden. This time it retreated, it was more than 5,000 points overnight, which is really uncomfortable! Make a slight adjustment to the short position, and go short at the rebound of 88,500 and 89,500. The target is 87,000, 86,000 and 85,000. The defense zone is at 90,000! At present, it mainly refers to the 4-hour level of pressure callback. The upper rail is under pressure and goes down all the way. It falls below the middle rail support, and the support and resistance are exchanged. Continue to look down to test the lower rail support. This is the current intraday high-altitude idea! #BTC连续破新高，你看到多少？ $BTC
