The blocked upside of futures refers to the situation that the price stagnates and fluctuates when the price rises to the vicinity of the resistance point during the rising process. Overshoot blocking is a strong trend. If the upside is blocked, the general price can temporarily rise to the position above the resistance point, leaving an upper shadow line, but it will eventually form a shock below the resistance point. After being blocked, the observation of volume and shape will become particularly important. Because this will determine whether the resistance is broken or reduced. (Note: There is a difference between blocking overshoot and falling overshoot.
