and all these that I have made mentioned, the only way you can improve on them is to seek further knowledge, because knowledge and self control is very important in trading if you want to be profitable and successful in the market.
Improving skills does not mean increasing knowledge. Not making the same mistakes when trading and improving to achieve profit in trading can also be called an improvement. Learning from one's own experience is something that will be most often done by a trader who wants to develop.
When you trade, the results will not always be as we analyze. From the mistakes that occur, you gain experience, which allows you to make adjustments. From there, you can gradually improve your trading skills.
