AUD/USD first support at 7590/85 but further losses target 7555/50, perhaps as far as good support at 7535/30. This could hold the downside, but below here look for a buying opportunity at 7495/90, with stops below 7560.
Strong trend line resistance at 7635/40 should be a selling opportunity with stops above the July high of 7673. However a break (and close for confirmation) above 7670 is a strong buy signal and targets 7720, 7760/65 and perhaps as far as 7790/94 into next week.
