If you have been in trading for such amount o time and have no result, I guess it's not the activity which you should consider as the primary one. I believe that you would better stay away the practice and dedicate your time to learning fundamental things. If you're fond of short-term trading activity then I think that you have to concentrate all your attention and time on learning information about levels, patterns and stuff like that. Otherwise, you will continue losing money or stying at one place. No doubts, that sometimes traders have bad days or even bad weeks, but if it has continued for several years, then something should be changed.
Yes, I have experienced this. You have to be very very obsessed about trading to succeed. Like you live and breathe trading. Actually, this can literally be said the same for anything else in life. Seriously, only you yourself can change it and no one else. Anytime you want to revenge trade or do some subpar trade, think to yourself, do you really want to do this knowing that you will regret it later on? Your desire to be the best trader you can be must be greater than your urge to revenge trade. Revenge trading is like gambling. You get lucky and win back your losses and feel super good, but if you lose you lose a lot. Treat trading like a marathon and not a sprint. If you treat it like a get rich quick scheme you are more likely going to want to do some YOLO plays that eventually are going to bust your account.
