Trend is bullish in four hours chart. Important key support level is present at 0.7284 price level. In past few trading days, price is trying to print a possible Bullish Running Triangle pattern. Now, I expect price to rise up to print bullish Wave d. We could buy now or wait for the market to first print all the Triangle legs. However; if a bearish candlestick closes below 0.7284 critical support level then I will stop myself from trading and re-analyze the price action of AUD/USD currency pair.
