Trading psychology - 1.) helps to be relatively emotionless (having worked in IB after uni for 2 years, the best are ruthless. Whether that is good or bad, idk) 2.) need to find a way to learn how to take losses without blowing your account up. Stop losses are a must but profit takers arent. Need a target and re-evaluation.
What helps me is knowing if I make a bad trade, there is still a pile of capital and another opportunity. Also not chasing the highs i.e TG1 today.
