I think the secret to making money from this is to use the news event as the entry point for a 8-9 hour trade instead of just doing the spike alone, because NFP and that last USD/AUD never retraced but just kept going.
Yes, some similar trade plan came into my mind a while ago. I hope I'll have enough time to do the research and start out with a new profitable trade plan soon. Please share your plan with us if you think whenever you have something concrete.
