Greedy is one thing that we should avoid. If you think you are greedy, it is better to take your profit before you miss that chance, and you can't sell at the price you want or at the high price. But we can't deny that greedy will always come to us, especially if our target price is reached, but we don't place any order sell at that price. And we will not place anything except watching the price moves up and down. If you do that, your target price will not fill, and you will wait for a long time before you can sell it at the price you want.
