Counterknock refers to the behavior of exchange members or customers who deliberately collude to trade or buy and sell with each other in a pre-agreed way or price in order to create market illusion, in an attempt to or actually seriously affect futures prices or market positions. Generally speaking, it is to buy and sell, with the left hand out and the right hand in, and pour chips back and forth between two (or more) warehouses of Party A and Party B. ..
The purpose of knocking at the door:
First, slowly push up the stock price to make room for future shipments;
The second is to create an active trading atmosphere. On the daily chart, there is a multi-directional pattern of "price increase and quantity increase", which will be eliminated after attracting the influx of followers.
In the past, it was generally to attract retail investors to follow up, but now it has become a common trading technique. It is still knocking when opening positions, knocking when shaking, knocking when pulling up, knocking when shipping, and knocking when rebounding.
