Speculation of petrochemical or Baosteel CWB 1 must wait for him to come down from a high position for n trading days before starting work. Because its general investment value is 0, general institutions can only keep making downward spreads to continuously reduce their own costs, and only when the time is ripe will there be opportunities for speculation. CWB 1 in Shanghai has been adjusted downward for nearly 10 trading days, and it just broke its position on the last day, but there was no panic, and it faced recovery at the end of the session. At this time, it is best that the stock market has been rising for many days and is facing adjustment, which indicates that it will open lower the next day. Man Cang should not hesitate to do so. Generally, the next day, it opens higher on the right, T+0. Don't imagine that it will open lower the next day, and the return of 10% is no problem. My QQ55097502 1.
