Gold- Switching to buy dips

Yesterday Gold dropped exactly from important 1680 zone resistance and, in a very short time, reached 1640 zone support.
However, bears were not able to also break under this zone and the price reversed back above 1660 and closed at 1665, leaving a Pin Bar candle on our daily chart.
At this moment the bias is bullish and it will remain so as long as yesterday's low is intact.
However, only a break above 1680 would signal a medium term reversal
