The so-called anti-pumping is because the market index has fallen for a long time, giving people the feeling that it can't fall. Even many technical indicators are in a state of oversold passivation. If you don't make a counter-draw, it will be difficult to continue to fall, and the disk reveals that the transaction volume has reached a heavy volume. Therefore, it is necessary to carry out a counter-pumping, and its intention is not an end, but a means. It gives people the illusion that it will rebound, but in fact it confuses people with the illusion of rebound. Follow the trend in such a counter-pumping market and you will be fooled. 2.

If you start to turn back near the top of the peak, it means that the upward pressure is heavy, indicating the end of the rebound.
