You don't have to monitor the markets all of the time. Just because you don't day trade, you're no longer a trader. You're still considered as a trader if you buy and sell at any time that you want. It is when patience comes and makes it as an important attitude to cater your success through trading. Patience in a manner that you only sell when you get into profit, you don't make yourself affected by any bad news but you go according to your plan of when and how much is the price you're about to sell.
I read what you explained and it is like trading management that every trader must do, patience and also a self-made plan is what traders must do to be successful, without proper trading management traders will have a hard time getting success.
It is part of it, the management. Every trader can be good in their own perspective based from what they do and how they make their trades worth. As always, you need to be well-managed when you trade and you don't have to get caught by your emotion lest you're used to it.
That will be your main enemy in trades if you're very much emotional in each of your trades and success can't be reached if you're mostly depending to it.
