The market enters a period of fluctuation, with a night-time high of 83900 but failing to break through further. In this kind of market, it’s hard to make trades. Today is the end of the month, and looking at the monthly chart, the market has fallen from 100000 in February to the current 83000. There have been two consecutive months of decline. The monthly support is the last line of defense for the transition between bull and bear markets. Currently, the monthly line has not broken down; the monthly support is at 78200-76500. As long as next month's closing does not break these two prices, the market cannot be considered in a complete bear phase. Therefore, I believe that this month, if it can dip back to these two price levels, it is still worth trying to build positions for short-term gains, with targets looking at the weekly resistance of 88500-91000. Whether the market can continue to rise depends on the weekly chart. It must stabilize at 91000 to have a chance for a second surge. In terms of intraday trading: the market is still fluctuating, paying attention to the defensive support at 82500 below. If this position does not break, a small-scale rebound will continue, with upper rebound pressure at 83900. If it breaks through, then look at 84500-85000. A conservative short position can be attempted around 85000, with a stop-loss at 85500. If it dips back and breaks the support at 82500, then a four-hour closing below will signify the end of the rebound, and we will look at the second test of support at 81200. If it breaks this level, then look at 80000, 78200, and 76500.
