GBP/AUD Multiple setup opportunity

GBP/AUD is inside of a symmetrical triangle formation. You could issue a scalp buy after the break and retest of the descending trend line, as it will try to reach the longer term descending trend line.
Once Price reaches the primary descending trend line, you need to wait and see if it fails to break through on a 4hr time frame. In the event it does break through, wait for a retest on a 4hr time frame, after the retest confirmation issue your buy and hold for at least 50 pips.
