Learn how to manage positions and easily deal with various market trends The core of a good position management strategy is to shift investment from gambling to rational risk management, with the primary principle being to learn how to short positions. When executing, you can refer to a clear mnemonic: heavy position attack in strong market conditions, half position balance in volatile market conditions, light position exploration in weak market conditions, and short position observation in falling market conditions. Using daily MACD indicators to assess market conditions, a golden cross may represent a strong or volatile market, while a death cross represents a weak or declining market. In a strong market (MACD golden cross), one can maintain a high position (70% position) and concentrate on holding a few high-quality currencies. In volatile market conditions (MACD golden cross turning to death cross or death cross turning to golden cross), it is suitable to hold 3-5 types of coins with a half position operation (40% or 60% position), mainly by buying low. In weak market conditions (MACD dead cross or dead cross trend), it is necessary to strictly control the position (such as less than 40% of the position), preferably not exceeding 2-3 currencies, and the operation method is mainly to buy low. In extremely weak or declining market conditions, the wisest approach is to hold an empty position or maintain a low position (20%) to maintain market sentiment, and only buy low in operation. The number of positions should match the market environment. If the market conditions are good, one can hold more positions appropriately, while if the market conditions are poor, one should be highly concentrated or short. We must strictly enforce discipline, plan our positions and strategies for the next day in advance based on our daily assessment of the market environment, control our hands, and not move around.
