Continue to reproduce the last sideways trend. In the past few days, it has been exactly the same, including the new high of 31500, and the details of the subsequent stepping back to 3w are exactly the same as the previous wave.

If you continue to refer to the last sideways trend, you can't fall below 29500; and pay attention to whether the daily line will turn into a shrinking triangle afterwards. I have lighten up and take profit at 30760 and 30100. Mainly because of the decline in CME positions.
There are probably less than 4 floors in stock, continue to wait and see
