Foreign currency Bank Account month end revaluation

Foreign currency Bank Account month end revaluation

I have a question i have 2 bank accounts one in USD and the other in EUR , how to make the month end journal entries for exchange rate revaluation , also how to maintain the exchange rates daily on Zoho books for the foreign currencies .

I made transfer from AED to USD Account , the balance should be zero in USD but it show balance of 1.2 USD and the balance in AED it was not as per the bank statement as the journal entry was made in ZOHO in USD currency with exchange rate maintained in the system.

I need clarification please with GL entries ,Thanks
