I tend to suppose that all traders should practice, it doesn't depend on your skills and experience, everything depends on how serious is your approach to trading. If you seriously approach to trading, then of course, you should practice all the time in order to develop your skills, because there is no limit of perfection. People always should develop their skills and it doesn't relate to certain activity, it relates to all activities and in my opinion, the matter is to never give up. No doubts, that sometimes you might have dubious thoughts about whether it's your activity or not, it's okay, all people pass this stage. If you will practice and learn, everything will be okay I'm sure.
