Trade Record Items
Net currency exchange rate change impact on trade profit or loss
This returns the portion of this trade's net profit or loss that is attributable to the change in currency exchange rate between position entry and exit dates.
The value will always be 0 unless your test was correctly set up for multi-currency strategy modeling and the stock traded has a different base currency than your account's base currency.
See Currency and Testing Multi-Currency Strategies for details on how this works.
