I am ever so mildly OCD especially if I am bored so it definitely helps me to avoid constantly checking something that is changing (sometimes dramatically) frequently. 

I day traded for a year between when I left my corporate job and really focused on my business full time and I did ok but I hated it because I was constantly checking prices. I would wake up in the middle of the night and be compelled to see what overseas markets were doing. Was a terrible lifestyle, at least for me. 

I've tried some of the others, but I just don't care about them very much.

The dollar exchange rate is generally the most interesting to me. I'm curious to see what being unaware of it will do.
