If you had a predefined profit target set at a 1:2 or 1:3 risk reward ratio, but as price gets close to that target you move it further away because you think price will keep going for an even bigger gainthat is greed, and it will almost always result in you making LESS than you would have if you just exited at your predetermined profit target. It can be difficult to exit a trade when it looks good and is in your favor, but most of the time, that is precisely when you should be exiting. Many traders hold trades too long, move their targets further out or set unrealistically large profit targets. All of these things are the result of GREED and they will all result in you making less money than if you werent greedy.
