Here are some simple tips to help you avoid losing money:
Sell quickly, even if you're only making a small profit, like 50 cents. Big investors might suddenly sell, and you don't want to be caught off guard.
Look at the price chart over different time periods to understand how the price changes.
Use indicators like MACD or custom ones, like the one made by Chris Moody, which many people find helpful.
Only invest money that you're okay with losing. Don't put in more money than you can afford to lose.
Be ready for anything. In the world of investing, unexpected things can happen.
