Don't short in a bull market, don't go long in a bear market. Don't sell at a loss in a bull market, don't chase up in a bear market!
1. Buy with patience, sell with determination, and hold on with confidence.
2. Buy when there is a small drop in the rise; sell when there is a small rise in the fall.
3. Buy in batches, don't lose money; buy all at once, lose more money.
4. Support levels will be lost if they are held for a long time, and resistance levels will be broken if they are attacked for a long time.
5. Both shorts and longs can make money, but only greedy people don't make money.
6. Eat until you are 80% full, and make 80% of your money from trading.
