Trading is all about risk-taking, so as much as possible you have be a risk-taker in the first place for you to maximize reaching your goal in trading. Now, the question is, are there chances for any not risk-taker to succeed in trading. It depends for me, since trading can be learned in time as well as the risks that are involved when trading. But as long as you know your ultimate goal why you trade, then you should adapt the required knowledge, skills and strategies, and even building yourself on how to manage calculated risks.
There's certainly no chance if they don't take any risks. However, it's important to remember that effective risk-taking must be supported by adequate knowledge and preparation, such as understanding the basic concepts of trading, such as technical analysis, fundamental analysis, and risk management. Yes, every trade doesn't always go smoothly every failure has a lesson. We should record every failure while trading so we can change our approach in the future. It's important to remember that taking risks doesn't mean acting recklessly. Proper risk management, such as setting limits and conducting in-depth analysis, can help minimize potential losses.
