Gross domestic product is the key economic growth’s indicator of any country from long ago. This indicator is calculated for every country and is based on the data on the economic agents of a country.
This economic indicator represents consolidated figures that reflect the actual value of all goods and services which were manufactured by the economic agents of this country. This indicator is calculated once in a year and in every quarter. It is a notable fact that the quarterly GDP reports have the greatest effect, and influence a market the most. There are two indicators of this type that are published with the different periodicity. Preliminary data are announced in the first place, and only then the adjusted indicators are published. A trader has to take into account both these data sources when working with this economic indicator.
