GBP/AUD BUY

The price has been in a downtrend since October 2020 (Red trend line)
and I'm expecting to catch the retracement move.

I can see that the price is in an uptrend since January 6th respecting the blue trend line and has reached a major resistance level.
I expect the price to fall back to the trend line, then expect it to continue the uptrend breaking the resistance until it reaches the downward Red trend line reversing the trend, indicating that the uptrend (retracement) has stopped.
