Well, after the bearish news the first chance to sell was 0.7700.
The RTG (room to go) down looked like about 0.7677 but that would be for a “normal” day.
This is a news day so perhaps another 30 pips down is reasonable.
Bottom line: Assuming a stop loss above the pre-news price (say 0.7770).
About a 50/50 bet.
Turned out to be a good sell as AUDUSD reached 0.7580 (not shown here)
