14. There is no certainty in trading contracts, only probability

Some friends asked me a question. They said, "Teacher, there is no certainty in trading, only probability. How do I understand this sentence?"

In fact, there are two levels, because this is understood literally? It talks about a logic, because the biggest feature of the trading market itself is that it is full of uncertainty, but if you look at this problem from a philosophical perspective? Then can someone make the uncertainty into a certain result in the end? Yes, because it turns the entire link of uncertainty into certainty. In other words, I may not make money in a single transaction, but after I make 100 or 1,000 transactions, I know that I can cause quantitative changes through qualitative changes in time, and time can be exchanged for space. After 1,000 or even 10,000 transactions, I can make money. The law of large numbers, so oh, in this way, its trading results are equal to certainty. So for each point of view, there is no unilateral statement that it is absolutely right or absolutely wrong. So what about the game of certainty and probability in trading?

I personally prefer to jump out of this question to answer this question. If you sublimate this question, you know what you are doing and where your problem is. Then what? At this moment, I feel that my trading results are full of certainty.
