You complained about your eyes affecting you very badly. Sorry for that but my suggestion to you is that you should do well to get a photo-chronic glass. It is a special type of glass that protects you from the light that comes from a device or gadget. With this suggestion I’m not saying that you should still trade on daily. Just like some persons has said here, not everybody that trades falls ill. So, in a nutshell, do not get to obsesses with trading on daily and even if you would, make sure that it is not every hour.
