It is not difficult to trade with discipline. Have you heard "plan your trade and trade your plan". That's exactly what it means by trade discipline. The things that most people seem to change their trade because they think the market might change but you just have to stick with your analysis unless you don't do it right. and I think there are many traders who still violate the rules of discipline and this is a bad habit, especially for beginners who don't have good information about how to start trading. Discipline is the leading way to bring us wholeness and wealth.
