How do you use 30 minute bars?

How are 30 minute bars used to monitor a potential trade?
I've read through a lot of threads and 30 minute bars seem to come up fairly often as a trade signal.
Can anyone provide me with some insight as to when to use them and what type of chart would they be of the most value in (i.e. monthly, daily, etc...)?

I switch them off.

How has the market used the 30 minutes under your observation ,no matter the bar (Pinbar,fubar,inside bar, little bit inside but oh sh!t no its closed as an outside bar with a chronological length being 240 minutes) ?

Why not just look at the chart and think "oh yeah from there to there is 30 mins, 47.5 or 2417 minutes !" (if you want,when you want)

Surley you/we can tell the time ? But whatever the time "happens" to be , what has and is the market doing over 1 ,10,75,648,3045 minutes/or tics ?

What's the time? Now is the time, is it? Possible answers. dont know, no, yes. Thats your clock. ?

30 minute bars are best used for fast drinking.
