Realistically an application has to take a snapshot. If you have continuous change of the exchange rate you never get a stable price and that would be bad <g>...

Imagine somebody sticking an item into their shopping cart and the price changing before the order is complete because of the rate change.

Typically you'd have to grab the rate at the beginning of a session and then at stick with it and use that same exchange rate for future calculations on orders. SO it'd have to be stored with the order data itself in some form.
