There is simply no safe way to trade! Always where profit is there and risk, otherwise we would all be millionaires .But the risks can be reduced, here's a couple of tips :
1. Diversify risks
2. Do not take loans
3. Do technical analysis
4. Stay up to date with all the news
5. Never bet all the money .
You know, many of the points you mentioned, I had to break. I think this is not the most important thing in trading. There are things much more important.
