We need to take risks to make money. But we need to take calculated risks to make consistent profit. Sometimes even with calculated risks, a black swan event can do a lot of damage to our account which can leave a scar on our psychology. The main thing for me is trying to learn not to attach myself to the profit I've made.
Some traders say that you have no emotions to trade the market properly. I personally think that we are humans and humans naturally have emotions. So I don't try to fight my own nature. I also know that I can't predict the market, so I don't try to. One thing that I can predict, is my own behaviour. It actually took me a few months to figure myself out, but I observed my own behaviour and try to manage them.
I now know how I react when I make/lose money, I know how I react when I win 3-5 times in a row or when I lose 3-5 times in a row. So I plan what to do when it happens. I know how I feel when I start to get greedy and I think of ways to deal with it ahead of times. I also know how I react when I'm fearful. Unfortunately, I haven't mastered fear as well as I mastered greed. But I am trying to deal with it. If people reflect on their actions and try to be proactive towards their own behaviour, then they will probably do be better traders. I personally don't try to get rid of my emotions, I just try to manage them.
In my opinion, the biggest risks in trading is our behaviour when we are emotional about a particular trade. This is the number 1 reason for my failures.
