Exchange rates from transactions

Each transaction contains a number of currencies (account, trading and tax currency) and exchange rates between these currencies. There is also the exchange rate system, which provides exchange rates between any currencies.
A consistent system of exchange rates, which takes into account the transaction rates, is established in the Infront Portfolio Manager according to the following rule:

1. The exchange rate between a pair of currencies that occurs in the transaction is read from the transaction.
2. The exchange rate between a pair of currencies that does not occur in the transaction is taken from the exchange rate system.
3. The exchange rate between a pair of currencies where exactly one currency is recorded in the transaction is determined as follows:
   1. A primary currency is selected within the transaction.
   2. The exchange rate between the primary currency and the requested currency within the transaction is determined from the transaction.
   3. The exchange rate between the primary currency and the requested currency outside the transaction is determined from the exchange rate system
   4. The resulting exchange rate is the quotient of the rates from b and c.

Reference currency

The reference currency plays no special role in this concept. It is simply one of the currencies that may be requested and may or may not be part of the transaction. For performance reasons, however, the exchange rate between the primary currency and the reference currency is calculated.

Return

If no value can be determined, "n/a" is returned.
