The FX Portfolio - Virtual FX Positions section of the Account window is built to show activity for currency pair trades for FX traders so that they can track average cost and running P&L on their currency trades.

Since the "Position" value may reflect the sum of trades executed in the FX market along with currency conversions to change non-base funds into your base currency, these "virtual" positions do not necessarily reflect an actual cash balance in any currency.

You can rectify the value of a Virtual FX Position within the FX Portfolio - Virtual FX Position section by right-clicking on the position, selecting Adjust Position/Average Price and entering a different value into the fields.

This will not execute any currency conversion, but will modify the value of this Virtual FX Position on the account. For actual, real-time currency balances, check the Total Cash field of the Market Value - Real FX Balances section of the Account window.

To avoid having currency conversions reflected in this panel, use the FXCONV destination on the order line.
