Datastream 7i uses a triangular conversion method to convert Euro zone foreign currency amounts, which means that foreign currency amounts must first be converted to Euro currency before being converted to base currency.
The two fixed Euro zone exchange rates are defined in the Euro column on the List view tab of the Currencies form (SNCURR). Do not enter an exchange rate on the Exchange rates tab for this equation. Datastream 7i uses these exchange rates to convert foreign currency to base currency using the following equation:
Euro amount = foreign currency amount/fixed exchange rate;
base currency amount = Euro amount x fixed exchange rate
