The trading gain is the same as the real gain from foreign trade.
The real gross domestic income can be derived by adding the so-called trading gain to volume figures on gross domestic product. The trading gain B or, as the case may be, loss B is defined as the current balance of exports less imports, deflated by a price index, less the difference between the deflated value of exports and the deflated value of imports. In the circumstances in which there is uncertainty about the choice of deflator an average of the import and the export price indices is likely to provide a suitable deflator.
