A successful doesn't just have a good market judgment but also has a good healthy practice. And over-trading is not a practice by them, it is just for those who are chasing their losses thinking that it could help to recover but not knowing this could also be the reason for incurring more losses.
I have noticed that over trading is the main characteristics of newbie traders and that is because of anxiety, greed, lack of self discipline. These factors will make such a trader to lose his emotion to control his trade. In fact, a new trader barely understand what is happening in the market and only what to chase every candlesticks like his mentor has mentioned candlesticks to him. Successful traders are those who have lost their money over the years and probably learn their mistake that they make and now get better with such experience. I believe a trader who is new and making profit is not yet successful until you have been experienced because at the time the profit is coming, it may be you are on the right trend but if the trend change, that comes the real trade challenge. Patience is important to be a successful trader.
For me, people who over trade cannot control their psychology and greed is still in their minds. Therefore, we also have to limit our thoughts so that we don't make mistakes. Usually people have experienced profits several times and continue to want to trade in one day, until the time ends up giving them a loss, because they don't want to lose and let it float, until finally they close with a big loss.
Yes, a trader is prone to losses when he is more greedy for profit. New traders often cannot control their emotions. Invest without understanding and open new trades when there is a loss thus they continue their investment as long as they have money. And those who profited, while hoping for more profit, suffered in the same way. Self-control is a key factor in trading. Over trading means guaranteed loss. A trader must take the right decision in this regard. A trader needs to acquire sufficient knowledge on how to control himself in an adverse situation.
