I follow some rules. Am not sure if they will work you for everyone but these are the basics.
1. Keep it simple. Once I tried to gather as much info before start trading. Many indicators, many news, vast analysis made me paralyzed to trade.
2. Avoid crypto trading on weekend and Friday too. Instead enjoy the holidays.
3. Never do Revenge trading, you will only trade whenever you have proper mindset.
4. Never love any asset, emotional trading will kill your investment.
Consider those tips as free gift, not financial advice. Always do your own research
Trading is something that forces one to have knowledge and practice, in my case I only make one trade per day and sometimes when the market is very volatile I prefer not to trade. I also define my stop loss and my target profit. Once I get some loss I stop trading and I trade again the next day, but I trade every day, I don't care if it's weekend or not
I only have two rules:
1. Buy low.
2. Sell high.
Unfortunately, I tend to break the rules often. I hope everyone else does better.
It is necessary to have basic knowledge of technical analysis and fundamental analysis, one needs to know where is the support and resistance and the patterns of up and down trend changes in order to buy and sell.
