In my experience, I highly recommend taking a break from the screen and have a little rest during the possible pauses. It is very important to give your body and eyes a rest. If you are constantly straining, you will get tired faster, and your efficiency as a trader will decrease. It would be best if you also rested to tame your psychological state. I often advise you to turn on soothing music and close your eyes. A couple of minutes of such rest will give you extra strength. If you are full of energy and do not require rest, I advise you to use your free time for training or to analyze your trading journal.
Discretionary does not improvisational. You need a plan to trade. Your entries need to be defined as well as your exits. Know where you get out if the trade fails, either with a hard stop (recommended) or adherence to your rules and when to get out when it succeeds either by a target, series of targets of clearly defined exit signal. Save your "thinking" for coming up with ideas and testing those ideas for viability.
