Fine tuning entries/exits in addition to increased granularity. For me, faster charts are mostly useful to observe things that can't be seen on slower charts during periods of higher volatility. It all boils down to volatility and trading style. I generally don't scalp for ticks, but there certainly are times when the 1-minute bars become very large. If you're waiting for that 1-minute bar to form or print a pattern - you're missing out. You mentioned using a 5-minute chart. You do realize that there are plenty of people who think that even a 5-minute chart and day trading in general is 'noise', right? Each to his own.
