Be cautious in short-term operations. When the stock price goes up, the closer it is to the high selling zone of important points, the more you have to guard against the main force's market crash.
To prevent a rapid decline, set a 25% position near the cost price in advance to protect the principal, so that the position is safer.
Once the market price is close to the cost price, immediately reduce the position by 25%, and wait until the stock price reaches the lower support level before replenishing the position.
When the market is good, leave 20-30% of the position to chase new highs after each profit stop. The 70-80% profit gained daily should be locked in time and put in the bag for safe, and focus on the big and let go of the small.
