Seems a very logical area for price to return to, many factors are converging on this one area. I think once this area is touched again, price can begin to move higher.
unlikely to dip bellow 400 which was a resistance and is now clearly strong support. See that red candle with a large wick on your chart? It has bullish confirmation as the following 2 green candles are engulfing that red candle. Besides there is a bigger and stronger move playing out targeting much much higher than shown in your chart.
