Trading is:
80% Psychology
10% Risk Control
10% Execution
Your might have a good trading system,yet not be a profitable trader,to be a successful trader goes beyond drawing lines on your screen or a few indicators.
Work on yourself consistently and intentionally first and the rest comes easy!
An experience trader always knows where and how much he has taken. It does not need to overcome the risk of psychology and other things. For new people, all these things can be good and good to learn, but experienced traders always see how the market can go. What you call lines or some indicators, often traders with these lines and indicators, and make good profit daily.
Every work has to face difficulties in the beginning, after which, as it experiences, things seem to be easy. What I think is the most important is a trend. If you understand this trend, you will always face good profit and less loss in trade.
