Due to the Dollar weakness, AUD gained a bullish momentum as shown on the 4H chart by the Price creating Higher Highs and Higher Lows. The break and retest of the 0.6870 HH is a great opportunity to enter long, this area has more confluence as it is where the price would probably bounce because of the 4H TL. Also, it is a major area of support and resistance that was tested multiple times and a 0.382 Fib. retracement (price always holds at this level after a very strong impulsive move).
