This week to next week, I want to change my strategy, mainly shorting on rallies. Two points: 1. The closer it gets to 4000, the greater the pressure; 2. This week serves as a transition for next week, which has the Federal Reserve's interest rate meeting and Japan's interest rate meeting, with a focus on Japan's meeting. There is no need to chase above 3680; I have already exited and will wait for a lower entry. If the market can reach 4200 and confirm stability at 3880, then we can proceed. If it's time to charge, then charge; if it's time to slow down, then slow down. Balance is key, that's the way.
