I don't know if I mentioned this on this thread sometime previously but this is the site that I use to check what the opening prices on a Sunday are going to be i.e. what's happened since Friday night's close:
Oz Forex Foreign Exchange | Inter-Bank Spot Rates
(Also useful sometimes to verify the prices you're being quoted by your broker i.e. the rates quoted are the live Inter-bank Spot Rates).
Why is this important to me:
Well: 'for starters' I know that AUD/NZD has moved 'south' over the weekend!!! Also: the USD has gained a bit of ground over the weekend.
