1. Based on technical analysis: set trading points according to historical price trends, support levels and resistance levels. For example, according to the technical indicators such as moving average, MACD and RSI, the appropriate buying or selling price is determined.
2. Based on risk preference: set trading points according to investors' risk tolerance and market expectations. For example, investors have a high risk tolerance, so they can appropriately reduce the purchase price when the price fluctuates greatly to obtain higher returns.
3. Based on market events: Set trading points according to the development trend of market events. For example, when policy, community, technology and other events occur, the appropriate buying or selling price can be determined according to the impact of the events on the price of digital currency.
