1. If the money is limited, you need to budget carefully. In a year, seizing just one wave of significant increase is enough. Don't always operate with a full position; keep some cash on hand just in case.
2. Your understanding determines how much money you can earn. If you don't understand, you won't make any money. Practicing with simulated trading is fine, but trading with real money can be psychologically stressful.
3. When good news comes out, if you haven't sold it on the same day, you should hurry to sell when it opens high the next day. Once good news is out, everyone thinks about selling, and the price will naturally drop.
4. As the holidays approach, reduce your positions a week in advance or simply don't sell. The market is inactive during holidays, and prices can easily fluctuate greatly.
