Trend is bullish in four hours chart. Important support is present at 0.7475 price level. In past few trading days, price is trying to print a possible bullish Running Triangle pattern. In my judgement, price has completed bearish Wave c. Now, price is moving up to finish bullish Wave d leg.
Wait for the price action to print all the Running Triangle legs and then look for a buy trading chance to join an up trend. However; if price breaks below 0.7475 critical support level then I will not take a buy trade and I will re-analyze the price action of AUD/USD currency pair.
