Trend has reversed up AUD/USD currency pair with a strong and big body bullish candlesticks. The daily trading range has increased as well. So, trend is bullish in 4 hours time frame. Short term support is present at 0.7137 price level. As long as price keep printing higher swing highs and higher swing lows, the trend is going to remain bullish. However a bearish break down in price below 0.7137 support level will end the current bullish trend. In such case I would prefer to stay out of the market and re analyze the price action of AUD/USD currency pair in 4 hours time frame.
