People are greedy.

I also experienced this once, because my mindset is that if I won a trade using my technical analysis, I can win the next trade that I'm going to make with a higher leverage for an easy profit, but it's not as simple as that, because trading is not always Christmas. We always forgot the risk management and the right management of our funds and profit, that's why we always lose everything and the rage trading will start.

Chasing the losses is the most case scenario for newbie traders, trading randomly because of their frustration hoping to make profits without any plan at all.
