Gold- Best place to buy it

I'm bullish Gold since Monday and since then, the precious metal has risen more than 500 pips. Yesterday, XauUsd made a small flag correction and managed to finish the day above 1720 resistance, which add to my bullishness.
At the time of writing Gold is trading at 1731 and, for short-term traders, is a little late to enter.
That being said, a good place to buy Gold at this point, in my opinion, can be 1717-1720 zone. The first target can be 1740, followed by 1765 strong resistance.
