You need a trading plan. You can basically consider it to be a blueprint for success. Your plan has to take everything that you can into account like entry and exit of money, risk management, time frame and even position sizing. Without a plan and too much emotion, you will be gambling instead of trading and you will never know how to improve your skills to become better.
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
