Very seldom do I trade other than EOD even for 60min charts. EOD is the only time that the direction of the market is the most clear. The openings are always a mess as the market tries to correct for overnight movements.
Jaws introduced me to the Dr Pepper trading method. Remeber the slogan, have a Dr P at 10, 2, and 4. That is when I usually check the market just to see what is going on. I also added noon. I actually try to be at my desk by 3:15p so I can made any EOD trade decisions. If I miss that time slot, I got another 4 hours before AH trading ends.
