The key market conditions are most likely around 3:00 or 4:00 in the morning, 5:00, 6:00 or even 7:00 in the morning. It is simpler and clearer to do things at this point dealer than to keep an eye on the market from time to time during the day. It's a pity that I was too sleepy last night and didn't catch up. Hehe. Judging from the overall trend, if this wave of big cakes cannot stabilize the support of 21500-21400, there is a high probability that it will continue to step back deeply. If I have the spot at this time, I will either come out to take over the market at a low level, or be prepared for a protracted war ( It is expected that the low sideways adjustment will last for at least a few months), which is equivalent to not seeing a fixed deposit. In the short term, pay attention to the opportunity for a position rebound, around 21400-21500, and the target is around 21800-21900. Defensive control 300 points.
