There are no undisciplined yet successful day traders. Day traders are extremely disciplined and have learned to eliminate the destructive traits that prevented them to achieve day trading excellence. You need to develop a set of very unique day trading skills to be a day trader, but it does not matter how skilled you get, if you do not have the specific kind of discipline to trade intraday, you will not get to the level of mastery in day trading without discipline and self control. Day traders are not “trigger happy” but instead they wait for their setups and avoid price temptations. They avoid market conditions they do not understand, and they can stay out of the “game” for as long as necessary. They don’t criticize markets with the same old “the market is rigged”, “the market is wrong” (all of them excuses) and the “the players don’t understand the economy”. In short, they don’t blame others for their own flaws (something that most people, trader or not, tend to do). All these reactions are emotional, and that is the one thing they do not wish to do. Instead they have self-control; at levels, most day traders only wish to achieve.
