Medical chart.

Euros to AUD.

Here's an important medical chart. There's a prepayment due today and hopefully the exchange rate will be at a favourable point on its (very bumpy) roller coaster.

Afternoon postscript: The chart doesn't help all that much because it shows wholesale rates, not retail. For this transaction, we'd have paid $300 less if the wholesale rate was applied. However we're only minnows in an ocean full of whales.
