In simple word, the price is the fee that buyer pay for the output or product that seller offer to him/her.
The price is the fee that buyer and the seller define as an agreement for the product.
The most important key point is the agreement
The price is the decision of the buyer for affording one concept and the decision of the seller for losing one concept.
The price is not fixed and changes all the time and even different from market to market and because of that we have opportunity to buy one concept or sell it.
The hole market is the movement of the price.
