Regarding the operation of chasing up and killing down, if it is in the central oscillation, it is certain to die. But if it is after the third type of buying and selling point, it is not necessarily the case, because the movement of the center does not necessarily end at the position where you buy and sell. Even if it is, there will be central oscillations later. Therefore, in this case, chasing up and killing down also has a chance to survive, but this is not a long-term plan. Even if you chase up and kill down, you can also use small-level buying and selling points to enter. Why do you have to guess blindly?
