Rollover Charges/Credits

Open positions will have carry charges or credits applied daily at 5PM EST (GMT - 5).  These charges/credits approximately match interbank conventions.  The exact amount, in dollars per lot, can be viewed from your trading software's Trading Window: 

The values in the "Interest Buy" and "Interest Sell" columns (far right) are the dollars per lot per day of carry charge/credit.  Negative values indicate a charge, positive values indicate a credit.
