That's why we shouldn't chase our losses and control our greediness. And maybe you forgot to add this in OP, it should also have a stop loss so that you can minimize your losses once there is.
I know it's very easy to say these things but for sure it's hard to do this especially when you forgot your goal. Trading it's always been crucial, we should have these skills, knowledge plus instinct.
It's all about how we can manage ourselves in trading, there's no shortcut, everything should gain with pain.
What you should do as a trader is actually quite simple when you write it down. I am not even joking, if you could write down what you should do as a trader in order to earn a lot of money, we would all mock about how simple it is.
But, the reality is that we are talking about something that is a bit more than that, human mind and emotions gets the better of us whenever we are trying to do something decent and that results with us eventually getting worse and worse. This is why it looks so much easier when you put it into words and that is why we do not have too many people doing those easy things. It is easy on paper but when you try it, your mind and emotions play you a game.
