Can someone please explain 'Volume' in a trade?

[Tradesurfer]

As explained if someone buys 100 shares- then someone sells 100 shares. If there is no seller(or buyer) then a market maker or floor specialist HAS to take the other side of the trade to facilitate a market at the available quoted price.

Moves supported by higher volume can be a confirming indicator.

One thing (pasted from investopedia) that some people look at is upside/downside ration- see below.

Volume Upside/Downside Ratio
The volume of advancing NYSE issues divided by the volume of declining NYSE issues. Investopedia explains Upside/Downside Ratio
If the upside-downside ratio is greater than 1, it shows that there is more volume in stocks that are increasing in price than in stocks that are decreasing in price. The higher the ratio is, the more bullish the market

Ok thanks.

My interest is really knowing if there are more buyers or sellers at any given Volume. Another words are they more buyer then sellers or visa vesa. Is there anyway knowing this.

I have seen some other sites they have an down pointing arrow and up pointing arrow next to the stock with percentage written next to them. I was hoping something like that.

on commec theres that market depth it will tell you both how many buyers and sellers which has placed an oder and are waiting for there orders to be excuted but as a limit order not a market order.. and obevesly a transaction can not occur unless theres a buyer and seller..
