I'm not too much of a trader but whenever you make a trade you need to have two numbers in your head, the price at which you are willing to take your profits and the price at which you will take your losses, set your trade and then forget about it for sometime, if you got your prediction right and the price went up you could readjust those numbers based on what you see on the market, but if you were wrong then sell immediately once it reaches the price at which you were going to sell.
