Risk avoidance means that an action can have many outcomes, and the possible outcomes of executing a certain action and the possibility of each outcome are estimated in advance. However, it is impossible to know in advance what the actual result of the action will be, mainly to prevent dangerous events. Risk prevention in the securities trade can generally begin with aspects of system management, supervision and self-discipline to achieve the goal of eliminating or slowing down the occurrence of risks. Risk prevention is deliberate, preventing and deliberately preventing the occurrence of risk losses through activities such as planning, organizing, controlling and auditing, and reducing the impact of losses to maximize benefits.
