The novice has been trading for a few weeks, paid tuition, and finally understood a few principles.
1: Find a place close to the support point and pressure level to open an order, because if you open an order in the middle, it will be repeatedly rubbed by the rise and fall, and you will lose patience and operate blindly due to the repeated mentality.
2: Relax after completing an order, otherwise it will be easy to be emotionally influenced by the profit and loss of the previous order.
3: The handling fees add up, and the profit is not much. All the handling fees are paid.
Move less and watch more. It's okay if you miss the opportunity. It's other people's business to make money. This is not a competition. Let's encourage each other.
