hi, just have a question on why the sudden move up today with aud. Normally when the us market is moving up the dollar will move up too but last night and this morning on my ig charts doesnt seem to show any big moves up on the charts but the aud managed to move from around the 8720 level which it was struggling to hold to a sudden strong move up to 88.

Any thoughts on why the big move up happened today?

Thanks.
