Is Volume Indicator Really Useful?

My question to Technical Analysts :- Is Volume Indicator Really Useful?

When somebody is selling means somebody is buying, and vice versa.
Then what is the meaning of price increase with high volume?
Isn't it also means price is increasing when someone is selling with equally high volume?
Is Volume is Popularity (or feel safe factor) of stock and nothing more than that?

I also want to know about volume indicator in Eco. Times. like highest and
lowest delivery at NSE.
Does it really indicate something?

Thanking you all in advance

I believe we have to think about a volume indicator as picturisation of the mass psychology.

If you guys are aware of famous patterns like H&S, Flag Pattern, etc it is clearly visible that any pattern when supported by relevant volumes gives superior results than the one without supportive volumes.

Check out most of the index scrip charts at their all time lows. In most of them, you will see wide Head and Shoulders forming with rising volume.

One of the only reasons why volume is considered crucial is that volume present impartial opportunity for judging the "Operator's cost"

Please give us some examples ie charts.
