Most traders have fail to understand that in trading it's very important to keep your ego aside and admit when you are wrong, cut your loss early so that you can try again .
I have seen so many traders watch there their position run into liquidation because they were stubborn or they believe that it can still reverse to their favour, when it obvious that their is no hope.
In my early days in trading I have my own terrible experience of failing to cut my loss early because I believe that their is still hope, but I learned the hard way when I got liquidated.
You wouldn't know how important this decision is, until you have been liquidated.
Learn to admit that you are wrong, cut your loss, restrategize and have a go at it again.
Although it may seem like an option or choice to minimise the loss, the feeling of losing money from a trade that you didn't look into until the end is painful, so if a trader can't wait until the trade ends, whether to take profit or stop loss, then it's better to not do a trade when unsure; don't enter the market if you know you can't see the trade until the end.
