Hey guys im new in the stock market.

Can anyone help me with this. A share price is determined by the demand and supply of the shares. But everytime when someone buys or sells the share, there will be someone on the other side of the transaction that is selling or buying at the same amount of shares. So how can we say that the demand/supply is higher when both side of the transactions are the same amount?

Sorry for this retarded question.

But the price of the share only changes when an actual transaction is done right regardless of how many there are in the buy/sell queue? Hmmm so confusing.
