Automatically hedging foreign currency transactions

Within the framework of the FX hedging concept, the rates published in realtime should always be used when currency transactions (FX deals) are posted. For this reason, the price must be updated both for automatic posting of currency transactions and for manual posting. However, it must also be possible to change a currency transaction without changing the price. For example, it must be possible to change the amount to be exchanged while the rate remains the same.
