...because trading is also a game of luck and there's no one person that is perfect in prediction, just that when you are favored, it looks like you're the champion but I tell you that no champions forever.
Trading is more a game of skill than just luck if you like to describe it in the sense of a game. People who master this skill become better over time; their win rates improve with consistency and practice.
If you think of trading as a game of luck, you would never really put in the effort to develop the skill required to be successful in that field.
It’s actually a combination of skill and luck, you don’t just trade proving your knowledge and skills, but somehow you also have to attract the market so that it will favor your trades, and that comes with luck. But most of all, trading with experience will always lead you to an edge and make you successful trader in the long run despite of how risky and uncertain the trading market is.
You fail, you commit mistakes and eventually you lose, and that’s part of trading. No successful and profitable trader has never experienced some barriers, but at least he/she should learn to overcome from all of these.
