Wave theory would suggest wave 3 can extend all the way to 0.5740, but lets be honest, the EUR is NEVER going to trade that low against the AUD. The only real way it might happen is if the EUR itself was facing extension, so I will discount that possibility.
Wave theory might have helped us to get in, but it’s a little more tricky now as, if this is wave 1, then we don’t really have a target to aim at as the bottom of wave 1 will pass us by before we know it’s upon us. So I will revert to some more simple fib levels to make a target price. Right now, I am simply looking at the first retracement level at 1.5485 (July 2012 low to Jan 2019 high (when the AUD dumped 2c in a flash crash)). Alternatively, if you wanted to discount that spike and take the more solid tops around 1.6340, then there is nice fib confluence at 1.5225 which corresponds with the top of sub wave 1.
These targets are a fair way away, so I intend to drill down into 4rh and 1 hr charts to do some fresh counting. And will update then
