DXY and AUDUSD scalp setup

I'm expecting the Dollar index to bounce from 200-800 MA's on 1 hour time frame. Considering am in AUDNZD sell and see Gold as a sell scalp, I will look to scalp AUDUSD from the .618 to the 200MA on 1hr. Then when DXY hits the 800MA I will probably be getting back in NZDUSD buy.
