I personally comment on the Shanghai Stock Exchange in an alternative way:Do you think today's Shanghai Stock Exchange is a success?Up 3% is 3509.

Then we will calculate the increase of Shanghai Stock Exchange today:Shanghai Stock Exchange is above 3481 and far away from 3481, otherwise it will step back on 3481!Through the above data, the corresponding increase of A50 is under the third pressure of 3566. That is, it oscillates between the second pressure zone 3481 and the third pressure zone 3566!

Up 3% is 3509.Do you think today's Shanghai Stock Exchange is a success?
