I can see here a strong h4 demand zone. This move was made by financial institutions because of the long leg out. There is a high probability that they have limit orders left placed exactly in our demand zone.
Further confirmations:
possible trendline retest
break of previous resistance
0.618 fib(golden ratio) in our demand - golden zone
strong weekly and daily uptrend
strong and fresh zone
Keep in mind that GOLD does not need to go down but if so, we are ready to enter.
