It is true that anyone will be able to experience losses when trading when they ignore things that they cannot do when trading, it is important when trading to be able to follow the rules and not let us do it with greed that causes us to lose the profits we have earned and if they want a big profit when trading it is of course a natural thing but they must also be able to Considering whether the decision they make is indeed natural and based on their knowledge or just because of their greed and there is nothing wrong with the small profit that we get if it is indeed something we can get consistently.
What rules? Does trading has specific rules? I think the main rule in trading is "to buy at cheaper price and sell at higher price".
Anyway, we can consider anything properly if we have good knowledge. So, it is important to make sure that we have proper knowledge before we start trading. We don't be lazy to learn, and we don't stop for further learning. This is also very important for each trader besides they also need to be patient and not greedy in trading.
Just suggestion: Please use a more effective sentence. It's a bit difficult to understand the point of your post.
