Why does the Cash Report section of my statement reflect a reduction in cash despite no trade activity or withdrawals?

概観: 

 

The Cash Report section details how each period's cash balance changes from beginning to end. If your account holds a long or short balance in a non-base currency, such balances will be translated (but not converted) into your base currency for statement reporting and account equity aggregation purposes. The rates at which these non-base balances have been converted are detailed in the Exchange Rates section located towards the bottom of your Daily Activity Statement. All other things being equal, any change in an exchange rate from one statement period to another will result in either an increase or decrease in your ending cash balance with the net change across all non-Base currencies being reflected in the Cash FX Translation Gain/Loss line. This does not reflect a realized gain or loss on these open currency positions but rather a mark-to-market calculation across statement periods.
