It's normal as you start making profits to desire more and more. This is going to be bad for your trading results if you don’t have self-control.
You might take a trade because you anticipate a reversal.
Or you might take a breakout trade anticipating continuation of the trend...
Whatever your position is; you have to set a price goal for when and where to take your profit or loss.
Once you set your particular goal, stick to it, this way you will protect your trading account (risk management) and avoid the mistake of being too greedy.
