Trade (or Transaction) Concept
The term trade (also designated by transaction) designates a transmission of property of a certain asset by counterpart of another asset. When both assets are goods, the trade is designated by direct trade. However, in modern societies, one of the assets involved is usually currency. In these cases trade assumes the way of purchase and sell in which who purchases is who gives currency and who sales is who gives the good.
Trades are usually made at the market, a place (physical or not) where is found who intends to sell (the offer) and who intends to buy (the search), whose, in a negotiable process come to an agreement about the price of the good and about the quantities of the good to be traded (or transacted).
