If you win the simulation, there is still a big gap with the real market profit. For example, put a long piece of wood on the flat ground, and many people can easily walk along it; Put the wooden strips 5 meters above the ground, and basically few people can walk there. The main difference is the psychological difference. The difference between simulation and firm offer is also here. When making a firm offer, all mistakes are irreversible. You should bear everything psychologically, and all real psychological activities will greatly affect your operation.
So the difference between simulation and real operation is very big. I suggest you think the simulation is ok. At the beginning, the firm offer operation is an operation exercise with small funds.
