IntradayThirty Minute setup on AUDUSD

I enjoy taking a miniature move within a larger scaled move. What we have on AUDSD is a 4h swing low to create a lower low. then a retest up to 38.8% then a rather quick continuation with the bearish trend. I'm looking to short on a 30minute setup. Simple lower lows and lower highs will support my decision to trade this pair.
