As simple as that. I believe over time, even day traders have already gotten used to the idea of checking charts almost all the time, that they never bother about the stress that comes with it since it is more like a job and the result is what matters. As long as you are a long term investor, there is really no need to be worrying oneself or giving oneself headache with the chart. Your business is with your portfolio and the good thing is that there are so many apps that helps one to keep tabs and even at that, you really do not need to be monitoring every single minute or hour.
