Hey this is for traders who are using IB and trading on foreign exchanges. How are you accounting for your gains and losses? If you make money in a foreign stock how do you keep track of it in other currencies?
For futures traders I recommend the Margin Account Calculator (http://www.users.globalnet.co.uk/~ibrant/index.htm). Have a separate spreadsheet for each currency and link the account balances into a separate master account spreadsheet that includes the exchange rates. You'll always know what your account balance is and be able to quickly reconcile your account statements.
