It is important to note that end balances in PropReports do not equal cash balances. End Balances (like balances seen on the Accounts page) are calculated by adding the sum of both the cash balance and the traders current unrealized P%L. Because overnight positions create a potential profit or loss, unrealized P&L does not affect cash balances, but do affect end balances.
The screenshot below shows how the Balance of 18,917.24 for a sample account on the Accounts page was calculated:
$24,517.24 + ($5,600.00) = $18,917.24
