What needs to be confirmed is your trading level, and then analyze the trading situation of each price. Closing a deal is the only thing you can analyze and judge. How many behaviors exist in the current price and how many prices will be generated later? Make a trading strategy according to this behavior. Perhaps this statement is vague, but it is the most powerful basis for studying the relationship between supply and demand. Volume and price analysis is the core of the trading market, and nothing can compare with it. The relationship between supply and demand is caused by human behavior, and people's emotions are fluctuating (greed and ignorance), so the fluctuation of the market is disorderly, so only by grasping the current imbalance between quantity and price can we stabilize the winning rate.
