The most popular time frames out there are the 1 min, 5 min, 15 min, and 1 hour. The best time frame? The daily!
I mean, do you really want to be glued to a computer screen all day? I hope not because trading any of the popular time frames would lead to such a terrible fate for you.
In addition, trading the daily allows you to trade multiple different instruments/assets at once with ease. Try trading 3 instruments at once on the 5 minute chart...it's stressful & a bad idea!
Plus, the daily has smoother price action than the timeframes below it.
As for time frames like 1 week, 1 month... they're bad too, it takes way too long to wait for another hlc bar. I don't have the patience.
The daily is the ultimate time frame, all you have to do is look at the charts once everyday. Not the 1 week, 1 month, or 1 hour, the DAILY.
